Back ground is in this thread https://dodgeforum.com/forum/2nd-gen...-***-ride.html

Well after seeming to fix itself the problem is back, but this time it does it if I get above ~45mph. The only other thing I noticed this time is that the steering was reall tight i.e. the wheel harder to turn than normal and the steering was off center, but the bump still feels like it is coming from the back.

I am going tomorrow to try and get some rear springs and spring bushings, prolly gunna rob some spring from a junk yard if I can, if not I am gunna be driving the JEEP for a while while I try and figure this out.

Another thing I noticed is that my truck has the "JEEP lean" going on from the back left area, also the area I think my vibration is comming from.

 

maybe you need new shocks? or your wheels are un balanced... could be the tire as well are there any flat spots on the tire..?

 

I think the tires and or wheels are junk, and maybe a spring is broke. As far as the lean goes, this is a common prob with the left side because the driver,battery,fuel tank etc.. is all on that side. And I think there is a TSB on the leaning issue, where they just put a spacer in the left front coil. And have you tried rotating the tires to see if any thing changes?

 

It actually went away for a while, the last time I tried to see if I could fix it after I put the tires back on it was gone. I am gunna replace the spring bushings and all the hardware on the rear springs and probally puth the smaller tires back on untill I get my tax refund back and have the Exchange order a set of tires for me.
