Diesel Dynamics, Joshua TX

Always doing loud burn outs and screeching tires day and night. And they are doing this to their customers vehicles at that.

This place may not be the cheapest place in town but they are really good people and fantastic diesel mechanics. You won't find anyone any better. You owe it to yourself as a diesel owner in Johnson County to give them a try. You won't be sorry.

I've had to bring in my 2001 Ford F350 to these guys two times for both (1st time for the ECM replace and IPR valve check; 2nd time for fuel pump replacement + transmission rebuild + down pipe replacement) and everything has always been great. Sometimes the expected completion date gets pushed back but parts can be backordered / unforeseen issues come-about and that's just the vehicle business sometimes. Never had an issue with communication and they're very thorough in explaining how things function if I bother asking. Thank you guys!

Had my AC compressor replaced on a F150 diesel, was told would be ready Wednesday or Thursday, they had it back Tuesday. Great work. They wonk sell you what you don’t need. Great experience, can’t say the same for the local Ford dealerships.

Crede was very honest and upstanding. He even held to our original agreement when it ended up costing him more labor and material. Great people overall!
Update: Turns out DD did not install the Bosch injectors like they said they were going to do. Had to swap injectors on my 5.9 again and the ones I pulled out of it were generic no-name injectors. I reached out to Crede but he said they were over a year old so there was no warranty.

I brought my 2004 F250 here after it was stolen. They did the diag and told me what I knew, motor was toast. As a mechanic that generally doesn’t trust mechanics, I can tell you that Crede and his team are 100% top notch. My truck is beyond where it was before and runs better then it ever has. Not lying to get a sale, honest and true. I can’t recommend them enough. Awesome job guys, have my business for life.

By the far the most amazing auto shop I’ve had the pleasure of working with. They keep my excursion in great shape as well as always keeping my fleet of work vehicles on the road

I drive an hour and a half and they will always have all my business what an excellent family owned and operated company Five Stars all the way

Superb folks who really know what service and taking care of customers means.

Old fashioned honesty and integrity.

Very highly recommend!

Diesel Dynamics is the only shop we will ever trust our truck with! After one shop that diagnosed the problem incorrectly and a second that could not find the issue, we were fortunate to find Diesel Dynamics. Mac took such great care of us and has gained a lifetime customer!

They have good warranty on their work. The price is fair. And they will answer any questions you would like to now about your vehicle.

My truck wont go anywhere else!
These guys have done every ounce of maintenance as well as my deletes, exhaust, S&B cold air intake, & custom tune since I've owned my 2012 F250 KR, and everytime I come in I tell them "if it needs it, do it! " 99% of the time I walk out with oil & filter change. They could easily try to upsale me but never do.even when I specifically tell them to "clean the S&B filter" or "do a trans service" they always come back and let me know that it doesnt need it yet. That within itself is unheard of nowadays. Great group of guys that will treat you right. Thanks yall!
