I have LML duramax Silverado , that I had been having issues with. I came referred by a friend with a LBZ that was really happy with the work and service. I can't say enough about the staff here. Very friendly and very efficient. I was kept in contact and truck was given back to me as promised in a timely fashion. I now have my go to shop for my diesel. I highly recommend them!

Out of all the mechanics we've dealt with in the past 12 years, Oscar and Justin treated our van with the most respect. It's been a serious challenge to find a shop that is knowledgeable and willing to work on this van that we love so much! Their work is clean and efficient, and everyone on staff is easy to communicate with. Janece is great too. They're a fun bunch! We recommend.

Iâ??ve used them twice and was extremely pleased. First time was about 10 years ago and the rebuilt the injection pump on my 1993 Chevy 6.5. It has been flawless since. The second time I was pretty sure my 2005Duramax needed a new turbo charger. I was prepared for a $3000 bill. Two days later I got a call that my truck was fixed, and did not need a turbo. Instead, the intercooler and pipes were filled with oil. The bill was about $200, despite the fact they knew I was prepared to spend much more. I believe that very few shop... read more

We have been going to UDS for years. They fixed our poor 2003 F350 every time it blew an injector. They were always honest with us, treated us fairly and never tried to add on to the bill.

This is the second truck I've taken to them, the first about 8 years ago, and this one. Both experiences were outstanding.

I brought Dave and Justin a 60-year old Cummins fuel injection pump. When I initially spoke to Dave on the phone, he indicated knowledge of my unit - enough to convince me that my Google search had paid off. When I delivered the unit to their shop, I found that Dave was busy on the phone but Justin gladly helped me out. When I told him of my issue (no throttle response after the engine was first-started after decades of silence), he indicated that a rebuild was in order. He quoted me the cost and I left the unit with them. H... read more

We are a local business in South El Monte with quite a few diesel fleet vehicles operating. UDS provides a various amount of diesel services for our trucks. We have been very lucky to be so close to UDS and use their services. HIGHLY RECOMMEND! GREAT STAFF!

The owner Janece is such a nice lady. My Ford F-350 had an oil leak and I took it to another shop and they told me it was the rear main seal leaking and it would be over $3k to fix. When I took it to UDS I told them about this and they told me they would research it and change the oil. They called me in the afternoon and told me my truck oil leak was fixed. They only charged me an extra $60 to fix the leak. This is a really honest shop, which is very hard to find. Thanks for taking care of me UDS!
