If your tires are wearing funny, if you just had any suspension or steering work done, or if you just want a piece of mind knowing your rig is traveling straight down the road and not prematurely wearing on your $5k worth of tires...Marty's Diesel has you covered. For the month of March we are offering alignment checks for $49 for single and tandem axle trucks or trailers, and $89 for triaxles. This includes a shake down of the front steering and suspension components, a visual inspection on the rear suspension, hooking up to the alignment machine and getting a print out of the results. Any adjustments needed would be an extra cost and would be communicated prior to anything being done. We can align pretty much everything from a car, to a bus, to a tractor and trailer, and everything in between. Call us to set up an appointment. 724-479-8000 located in Homer City behind Sheetz
