I limped my truck there because i was down the street and got a nasty vibration and noise. After…read morekeeping it overnight for diagnostic, I was told that my front passenger wheel bearing was bad. The noise was coming from underneath the cab, the wheel bearing was less than 2 years old (Moog), and the noise/vibration was nothing like a bad bearing. Furthermore, the tire did not wiggle at all when lifted off the ground. After taking it home, i did my own diagnostic and found the transfer case fluid burnt and full of metal shavings, the forward u-joint on the rear driveshaft was getting hung up, and the middle u-joint on the rear driveshaft had completely destroyed the needle bearings. Swapped out the transfer case and the 2 bad u-joints and both the vibration and noise went away. Take caution of what they diagnose for you. I'd been out easily $500 for the bearings and it would have not solved anything.

Called a week ago and they were extremely busy and had me make an appointment for a week out. No problem, told them the check engine light was on and the codes were coming back with something to do with the turbo. Roger said bring it in and we'll take a look at it. Well the day finally came (yesterday) and I dropped my truck off at 9 AM. Got a call around 2 PM with what the issue is (turbo actuator). Roger said they could get the part in tonight or tomorrow and get it fixed by tomorrow. Which worked perfectly with my schedule so that was great. I was told a price which was really reasonable for the work that was being done and the factory part. Roger called around 1 PM today and told me that was the fix, and my truck is ready for pick up. I will tell you what is awesome about this place: No BS! Absolutely to the point, Roger is a great guy and knows his stuff. Timeline for repair is quick! At least mine was. Great communicators - called to follow up with is excellent. Seems like a family business. Roger had his kids there and it was nice to see a family run business in Norco. Am I going to bring my truck anywhere else? Absolutely not! Diesel Powerhouse is the place for me. Will definitely be back!
