    It's hard to trust mechanics especially with my classic impala. But Jr. made me feel at ease with his customer service and experience. Just came in for an oil change and find out why my a arms were so damn squeaky....he fixed me up real quick and I was back on the road. Thanks Monzon's Garage!

    I just got off work and have needed an oil change! I came straight to Monzon ' garage. I could've stopped at alot of different places along the way but the mechanics at Monzon's garage are so awesome, honest and caring! It's family owned and they have been in business for over 40 years. The shop is located in downtown fullerton. There's plenty of places to eat, shop or maybe just take a stroll while waiting for your g-ride. I ended up getting my rotors turned, tires rotated and an oil change. I am so ready for the weekend. Thanks Joe! You truly are the best!

    Family owned from the ground up one of the best mechanic shops in town

    Jorge was great! The team replaced my coolant reservoir within an hour of me arriving and did it for a good price.

    Joe undercut the competition on a higher performance clutch system and did a great job, with same day service.

    Jesse was amazing! I messed up doing my own oil change and ended up over torquing the oil drain pan…read morebolt, so my bolt wouldn't stay in. I made an appointment with him the night prior at 10pm and he promptly came out the next day at 8:30AM to fix the issue. He retapped the threads I had stripped out and fixed it for me. He also made sure to drop my oil pan and clean out the metal shavings so they wouldn't get into the engine and put a new gasket on when he reinstalled it. He also completed my oil change. He was able to finish the work in less than 2 hours too! Thank you Jesse for your great help! You saved me!

    Really surprises me that you have time to post a long comment on a Yelp review, yet after three…read moreweeks of ignoring my calls and texts, you still can't take a moment to explain what's going on to me directly. That alone shows the type of person you are and how you treat your customers. I have screenshots of our entire conversation that I'll be attaching so everyone can see the lies you're telling. I have never gotten hostile with you I've been patient and sure I was bothered by you changing the story line every hour I have not once yelled or been unprofessional with you like I said I have all our chat history for everyone to see for themselves and see how you are just making up things to make yourself look better. To start, I told you from the beginning that I did NOT want to replace the axle. The boot just torn, and it didn't need replacing-- even Toyota recommended simply rebooting it since my truck only has 15k miles. So I'm not sure why you're lying and changing the story now. The boot and axle were both inspected by Toyota before hand they said I should just replace the boot as soon as i got a chance. As It can fully tore and grease could leak out so I've had it sitting since then to play it safe so you saying the axle was already worn is just a straight up lie. You even said being it's a new truck you shouldn't have to replace the whole axle when you showed up. As for the lug nut, I never gave you permission to damage it like you're claiming. I came outside and you were already hammering on it, struggling to take the key off. You told me it wouldn't be an issue and that once you reinstalled it, it would come right off with a couple of hammer hits -- which did NOT happen. Good thing I stopped you, because who knows what else you would've damaged. You also installed a $160 aftermarket CV axle that you purchased from O'Reilly. I'll be attaching the screenshot of that as well so everyone can see. And no, you did NOT arrive at my place "near midnight." You arrived at 9:25 PM -- I have proof of that too. The reason you were there until almost midnight was because you destroyed the threading and then sat there for almost an hour and a half trying to figure out how to fix it. I tightened the clamps because you were trying to install the axle exactly how you brought it, with the clamps loose. I told you they weren't going to hold, and you said you couldn't get them any tighter and that it was "fine." So yes, I took it upon myself to fix them because you were trying to take shortcuts to get the job done. For reference, my OEM axle costs $450 after tax from the dealership -- not including install and $70 I also spent on the rebooting kit that was also "thrown away". The one you installed only costs $160. So yes, I have already filed a police report and I am starting a court claim. See you in court. And thanks for showing everyone how you treat your customers.
