"William is a awesome guy. He did a great job. Called about the tandem axle not sliding and helps me fixed some other little issue. I definitely recommend austin fleet services"
"These guys are great, had an emergency with a DEF pump on a black Friday, only shop that picked up the phone, took my driver in immediately and didn't give me the runaround like most do now. I asked not to diagnose anything and just change the pump. Truck back on the road in 3-4 hours and saved us at least 3 days waiting for another shop to open. Definitely coming back here next time our trucks are in the area!"
"Outstanding experience with AFS and George, their knowledgeable mechanic who replaced my valve cover gasket. My vehicle is running smoother than ever. Thank you AFS!"
