Anthony and the guys are awesome. Very straight forward and honest. They re geared my front and rear axles in Septemberof 2023. Took the truck back for oil changes and inspections, got the truck back with a clean bill of health for the axles. The gears have about 26,000mi on them and no wear issues and no noises. 5star group for sure, highly recommend. read more

Anthony took great care of us! Dropped off Monday and back on the road by Wednesday! Thank you guys! Service truck is back on the road!

Hoopers gets a GREAT. If you need a diff done please get over here and they will treat you right. I did mine and immediately did a Cali to Oregon drive and the truck is running perfect! Amazing clean shop, good level headed mechanics, service is professional and they referenced a amazing shop to do my transfer case as well. read more

They were very nice,informative, and took the time to discuss the proper application for my needs. I highly recommend them.

I've been twice within the year. Back in January I had the shop install an OS Giken LSD into a stock A80 Mk4 Supra Differential. That setup ran great, but I eventually needed to switch to a lower gear ratio. I took the LSD and swapped it into 98 GS400, and had them recheck it. Anthony didn't charge me a dime to verify my backlash, and gear pattern. These guys really know everything from stock, to high horsepower modifications. Best place in the SFV Valley. Thanks Anthony! read more

Took our Land Cruiser in for new gearings. First time to their current location. Due to new location we picked up a rental car first. We were told 2 days & given a very reasonable quote for the work. Got a call the next day at noon all done! Saved us $$ on returning the rental & more importantly the truck is driving great!!! My husband said he only trusts Hoopers when it comes to working on his pride & joy! read more

Completely rebuilt rear end lasted 10,000 miles then started falling apart. Found out they left the valley so I had to have it rebuilt yet again. Bearings were spent not sure how that happened so fast. Was told this was "the" place to go. Pretty bummed. read more

I took my Dodge ram 2500 there to get the pinion shaft seal replaced on my 4 x 4. Literally took these guys no time at all to do this job, they were extremely proficient, professional, and fast. I highly recommend getting any differential servicing you need done through these guys. read more

I have had Hooper's work on just about every truck I have ever owned. They are the best at what they do. Not once have I had an issue with the a diff that they have worked on. They helped a friend of mine put together a custom built rear end for his Scout and twice I have been there when they were fixing what another shop messed up. read more

This is the type of place and people that are so hard to find. Our rear differential exploded 2 days before we were gonna go on a trip. I went to them in search of some Toyota ring gear bolts and a bearing swap they barely charged me anything for the labor and gave me the bolts for free. Will be going back for regear. read more

Just had my Chevy Express van rear end rebuilt. Anthony was very professional, cordial, and stuck to his estimate. Dropped it off one day and picked it up the next day. Same service I got in the valley in the 80's on my 71 Chevy Pick-up when he was (Down the hill). I highly recommend Anthony at his new shop. read more

Had to get the rear end on my 2003 dodge ram rebuilt after 270,000 miles. Priced it out at a couple places, Hoopers was able to give the most accurate quote over the phone, it was a totally fair price. My wife dropped it off in the morning and it was ready the following afternoon. They did a great job, fast service, fair price. They have all the right things going as well as good customer service. read more

My 2500 Silverado Rear Differential housing had a large crack and water from the boat ramp damaged everything inside. Hooper found me a used housing and replaced all the bearings seals and replaced my 3.73 gears. I even paid extra to have them replace the rear hub wheel bearings and reseal the front differential. These guys are the best in California and stand behind their work, This is their specialty. They got me back on the road in just a couple days. That's pretty impressive for such a big job. Thank you Greatly appreciated. read more

Hoopers Rear End - Rear Differential - Auto Parts & Supplies Near Me - Leona Valley, California

The guys at Hoopers are life savers. I live in the San Fernando valley, went to five shops and was told by four out of the five I needed an entire rear differential replacement, would take 7 to 10 days to do the work, and I was given estimates north of $4,000 for my 2020 Ram Rebel. A newer truck needing an entire rear differential replacement sounded off to me, then I was referred to Hoopers by a family friend. I made the trek out to their new location in Leona Valley, and it was well worth the drive. All I needed was a new bearing , and they had me out of there with my truck sounding like new in less than three hours. Hoopers rocks. read more

The Hooper's owners and staff are incredibly knowledgable and nice to work with. Love the new location in Leona Valley.

Anthony knows his stuff .. professional, breaks it down and price is fair. When it comes to your differential, you don't want cheap, you just don't want to get over charged . Hoopers is legit ! Thanks Anthony ! read more

I'm working on a project 56 truck and received my rear end fully assembled but raw from the manufacturer. So I'm order to powder coat the housing it had to be disassembled and then reassembled. So I brought it to the legendary Hoopers. First point I want To make is that the rear end was taken apart almost immediately. But I had to go so I came back the next day to find all My parts placed neatly in boxes. And the housing quickly loaded in my truck. After I brought it back for reassemble again it went together super quick. Second point I wanted to make was regarding customer service. You'd almost expect auto shops to inherently have pissed off old guys working the counter. These guys here really understand customer service. The service I experience here was probably some of the best overall service I've had through my entire build. Highly recommend these guys. read more

I was changing out the rear axle to a 3.08 in our '84 Chevy El Camino and had calculated the axle ratio using the number stamped on the outside of the axle which was originally a 2.41 axle. I started the job and discovered that the previous owner had installed a 3.42 which uses a series 3 carrier. I couldn't use the Series 3 carrier for a 3.08 ring and pinion so after doing a quick Yelp search, I called Hoopers and they had a used Series 2 open carrier sitting on the shelf. An hour or so later I showed up with my Series 3 carrier and Anthony swapped the bearings over to the Series 2 and sold me a new pinion nut too. We chatted about how to set the pinion preload and Brian even gave me a booklet that explained the process step by step. Stepping into Hoopers is like going back in time to how auto parts suppliers used to be with knowledgeable, helpful staff who know their stuff. I miss shopping at places like this. read more

I had heard about Hooper's rear end shop in Sun Valley through the Jeeping grapevine and its easy to understand why, these guys are experienced, patient and have built a reputation for being experienced with all types of rear differentials. I recommend getting rear end fluid changes here so that the person inspecting your differential knows what to look for, they're an awesome resource to have. The area of their shop can be a little daunting, it is a narrow busy street full of industrial and auto shops - my Uber driver was not happy. read more

If you need work done on your axles, look no further. The staff is very knowledgeable and helpful. The work is top notch and done quickly. I found them through my long time mechanic and was very happy with the work they did. I have an older Jeep and each time I managed to break something off-roading they were able to fix it quickly and get me back on the trail. read more

Brought my customer's axles out of a 64 Cadillac Deville to replace the bearings and they did an awesome job. Very reasonable pricing. Professional & Knowledgeable staff and great shop to work with. Highly recommended from another professional mechanic! I'll be bringing my own cars for work and recommend to other customers looking for rear-end rebuilds or replacement. read more

The Very Best In The Wild Wild West!! My experienced with Hoopers from the past it's been positive they know what they're talking about when it comes to rear ends :-) read more

These guys are legit. Very friendly and knowledgeable. They did two separate jobs on my Jeep and both times the work was top notch. The part that they worked on was left clean and looked new. They showed me the parts they replaced. The cost was very reasonable for the work they did. I highly recommend. read more

Anthony and techs did a great job installing Eaton truetrac in my S197 8.8. My first torsen style diff! Very excited to take the car up to angeles crest. Just picked up the car today and drove it home. Absolutely no issues. No noise, very smooth. Just like the OEM Ford trac lok but I can feel the difference through the drivetrain and shifter, it's tighter. Initially, I dropped off the diff, seals and complete gear installation kit. I thought I would have spare bearings and shims etc left over from gear install kit to pick up since it was just a diff swap. Nope! I was very surprised to find out that the tech actually dropped the whole rear end, went through the whole thing using all the parts supplied and even painted the housing. That's a lot of work in such a short period of time (2 day turnaround) Original quote/estimate Anthony provided never changed. I recommend Hoopers period. This business is on point! read more

This place has been the best in the industry for decades. Glad they are still going strong. I arrived at 8am, received a quote for repairs at 10am and another call at 1:30 when the truck was repaired. Worth every penny! read more

years ago i bought a rear end 3rd member for 395 dollars for a 3.55 chrysler 8 3/4, best price anywhere and it lasted at least 20 years before the limited slip began to fail, and it endured many hard miles and long burnouts too. I bought another pumpkin from them after that one failed and it was only425 this time. Now this was 30 years ago and the second one is still working great. read more

Great customer service! Took my Tahoe in and they were able to replace my worn out axle bearings and get my car back to me the following day. Thank you guys! read more

I took my 1969 Camaro to Hoopers after experiencing a rear end issue.Being that the car is 54 years old,I knew it was pretty serious. I spoke to Anthony explaining what the rear ended was doing. From our conversation he knew what the problems could be. I dropped it off Monday afternoon and it was ready to pickup Wednesday.Driving home and going thru the gears put a big smile on my face! Great team great service and one happy customer.Thank you Anthony and Ryan! Rick V read more

Terrible! After having them inspect and change oil in my rear differential, Within 50 miles I had problems with my Detroit Electrac locking differential. Now I have a broken shift fork (no longer available) and slightly damaged ring and pinion, and my jeep cannot be driven. I had to remove axles, differential, and pinion to get the broken part out of the housing. They must have installed the shift fork incorrectly when reassembling, but will not admit it. They refunded the $250 inspection fee. Hoopers said I should buy a new differential ($1000+$450 install) since mine is "obsolete" and now broken! Unacceptable! Even after I had the Bureau of Automotive Repair contact them they will still not help me! UPDATE (after Hoopers replied to this review): Hoopers reply has several errors/lies: 1)At no point did Hoopers tell me: "your unit is worn out and not engaging ". 2)At no point did Hoopers tell me: "the shifting mechanism was worn out". 3)Hoopers did NOT tell me that I was not supposed to run it in locked mode. I never selected lock mode, but because the shift fork was broken (after being installed incorrectly) it engaged in locked mode (or partway in between). 4)Hoopers never told me that it would break if run in locked mode. 5)It is obviously NOT impossible to engage the shift fork incorrectly. I have since had the shift fork professionally welded back together, reinstalled, and now everything works correctly. I have been testing it for the last few weeks with no issues. If Hoopers had actually told me the above mentioned things, they would have been completely wrong. read more

Took my car in to swap out gear and pinion. Once complete car came back with abs sensor light and traction light on (was not on when dropped off) They explained that this was normal and expected instead of taking responsibility. Took it to 2 other third party mechanic and was told the light was due to sensor wires being damaged during the gear install. Long story short - in the process the car came back with gears installed but with additional problems (wheel speed sensor damaged as well as ABS sensor damaged). Very unfortunate since I had other projects I would have wanted to utilize hoopers since they are the gear experts in SFV area but I will be taking my projects elsewhere - even if I have to drive further away than deal with this headache again. read more

I drove in from Palm Springs - in arriving I was expecting that they won't be able to get it done because I arrived so late in the morning. I drove 45 miles per hour - from Palm Springs - it took longer than expected. Bless their little hearts the guys moved around some schedule repairs to fix my car in three hours. When Anthony test drove the car he asked me if I drove the car there "rolled his eyes like OMG" I was told I had no oil, all the bearings and whatever else is in a differential was melted. I was apprehensive in doing the work since the two transmission people in Palm Springs quoted me higher prices and a three week waiting time to finish the car - and hinted to me that I would be ripped off from Hoopers. This was not the case - the car drove better than it ever did - the guys were polite and completed the rebuilt in three hours. Thank you McNally Automotive for recommending Hoopers Rear End - they exceeded my expectation after my visit there and getting my car done. read more

They rebuilt two different differentials on my trucks. Second one sounded worse after rebuild then when we brought it in? I overheard owner talking about using used parts ? Omg ! Had to beg them to redo the differential we paid over a $1,000 to have done right the first time ? Horrible customer service and as a observation seemed shady with the use of used parts ! read more
