My friend was following me in his truck to one of my garages that I rent. When we got there, he tells me that my truck is dog tracking big time. To make sure he wasn't bull####ting me, I let my friend drive my truck and I followed in his car.....confirmed major dog tracking.
The dog tracking could be the reason I have the vibration coming from the rear that comes and goes and it's getting worse. It begins when I approach the 70 mph area.
I checked for broken leafs, U-bolts, things shifted, mostly checked the obvious stuff and everything checked out. I did not check the centering pin on the leafs/blocks. When I take off from a stop, I get the feeling of a worn pinion but the pinion is tight.
I took some quick measurement tonight and found that there is a 1/4" difference fore and aft on the rear. This leads me to believe that the thrust angle is off. If the rear is not centered, the pinion U-joint is not parallel with the trans/c
xfer case. Would this difference cause the dog tracking and vibration?
The problem I am going to run into is finding a body shop with a frame machine big enough to fir the truck on. And the other major issue is finding a 4 wheel alignment shop that specializes in lifted trucks. In my area no one wants to touch something like this. I am willing to travel to PA, CT or upstate NY to fix this problem.
I had a set of custom traction blocks made for my truck. I am wondering if the guy put the centering pin in the right location. The truck has a 2"-3" lift on it.
Comments and/or ideas. Also any shops that would do this kind of work?
Truck is a 1997 F250HD (old body style) 8' bed/ Super Cab. The TTB was remove and a solid axle Dana 60 was installed.
