We took our newly purchased used 95 F250 up in the snow yesterday. I found that when we were climbing in 4WD the left front wheel was making a loud clunking noise. I'm pretty sure it was in the wheel area as opposed to the engine or center of the front end. It didn't make the noise going down hill, only pulling. It has auto hubs? Ideas on possible problems? Thanks a million.....new Ford owner.

 

u joint, or worn spline at the hub maybe?

 

vacuum hubs????

 

auto locking hubs could be failing to lock in , an are slipping
