It almost does seem like the shock isn’t dampening and tossing the entire truck instead.

I once drove a friends toyota pickup that had blown out rear shocks.. Whole back end bounced up and down after going over a speed bump.
So I think one blown shock could do it. And if one is bad, maybe you have two bad ones. On one side or diagonally..

Once drove a Jeep wrangler with swaybars removed, a lift, and larger more offset wheels. I was scared to go 25mph down the street the thing wiggled so much!
Very squirmy feeling. I've driven old dodge trucks with worn out steering boxes that drift back and forth, and this Jeep was much worse!

Another clue. I noticed when the road is imperfect let’s say one side has a little dip. The entire truck sways. Like I have to brace myself


something that bad I feel like you could just push done and bounce the truck and see. it really shouldn't move at all.


on a scanner you can see the voltage from the ride height sensors and the power being sent to the shocks to adjust the dampening.

I'm surprised you don't have error codes for suspension. they seem to be pretty common when something small. happens and this doesn't seem like a small issue.


arw the sway bar end link in good shape?
