sudden tire wear

Ball joints??

 

truck's don't have ball joints thay have king pin's

 

Shocks. When was the last time they were changed?

 

Ball joints on the steering linkages, test them by squeezing them with a very large pliers, if they click or you get a knocking feeling you got wear in them , checking the kingpins is a good idea too.

 

Could be but I reckon if it were shocks it would have 'cup' wear

 

Tires wear like that when air pressure is too high or low..also something has to be out of whack considering that's a drive tire(check tire pressure)

 

Im confused, is the failing tire a wide based drive? Hard to tell from picture. Both steeres were replaced 15k ago and this tire has 160k? Did you check all 3 axles for alignment? Its hard for a trailer to screw up truck tires unless they are way out of wack. Generally the trailer will just off track. Contact Mike Beckett from MD alignment though. http://www.mdalign.com/ He knows everything there is to know about tires and is quite help full. He it quite literally a tire and alinement genius. Also, did you check alignment yourself? Did you drive the truck forward before checking? TA/petro and other express locations have no idea how to check it properly.

 

Do you use the jake much ? My old dafs used wear the inside of the inner drive axle tyre on the right side ( side with the longer half shaft ) from using the retarder a lot on mountains.
