Many things could cause this but usually it’s something worn out but most shops will not do an alignment if there is any slop in the steering or suspension components

So everything up front is solid in great shape and everything in the rear is solid also?

Was the rear axel ever worked on?

 

I unbolted one side of it about 2 years ago. I decided against installing the lowering kit, and I put the 2/U bolls back. I don't remember if that's when the pulling started or not.

 

Now there is something I would check on I’m no expert on the rear axle if they self-align or you need to measure them and make sure both sides are exactly the same.

Something to check on

Also saging leaf springs on one side could do this or one side worn out bushings

 

They have a pin that it self centered on. But...I could measure....where would I measure? lol

 

That I dont know check the FSM

 

I don't see this being excessive?

More tests later.

 

I looked in the FSM and it looks like the axel is self-aligning.

That looks normal to me in the vid.

 

I remember it aligning with little pins or something when I bolted it back up.

The rear brakes don't seem to drag, but my LSD makes it behave weird so I can't really get an accurate reading....or something. (I've never tested brake drag on a car with an LSD) I plan on taking a long drive today and seeing if one wheel is hotter than the other.

My only other options are tires (unlikely) and something being bent or a bushing being bad. (semi unlikely)

The truck only has ~75k on it... but i noticed an oil leak at the front by the big pulley? (harmonic balancer?)

 

If they are dragging some you should see some discoloration on the rotors it may only look like rainbow discoloration but a bad drag they will look blue black you can’t miss that.

Another Blue black one this one is more blue depends on how you look at it the angle

 

Both of my rear brakes *might* look like that...I'm not too certain. I know I'm due for new ones anyway...
