Hearing a pop and then a pull left

CK. the ft. springs for a broken tie bolt

 

The pull to the left could be a problem with the right brake. Possibly caming over,broke spider,cam bushing gone.

 

I would check hub bearings also.

 

What year and make? Seems like peterbilt had a problem with u-bolts on 13 or 14 579

 

Brake jammer? The nut behind the wheel?

I've been to a few Freightliner shops about this problem. They can't find out what's wrong... sucks in the winter when it wants to pull to one side before it pops, and then wants to straighten out.

 

My Prostar did that once I a while also, found the brake lining cracked on both sides of the steer axle, had new brakes and drums installed and hasn't done it since.

 

The tie bolt goes thru all of the ft. springs in the center of the springs the head of the tie bolt sticks thru into the steel ft. axle no part of it shows, you can ck. to see if the ft. axle is moving by looking for marks on axle under U/bolts where its been sliding back in forth on the springs, or you can roll down window an move truck then step on brake while sticking head out window and watching ft. end move when you stab on your brakes if its the drivers side get a helper to watch the R. side for you?
