    Hey guys, installed my Eibach leveling kit (Springs and shocks) about 1000 miles ago. When going around a turn and hitting a bump the rear gets loose. I know my 285/70/17 AT tires (35 psi) do not help but I am wondering what I can do to tighten it up. Aftermarket swaybar? I already have the poly bushings in the stock swaybar.

    Are you unloaded when this happens? Are your rear springs rated for extra load?

    I had this issue with stock suspension. I put eibach springs in the rear. New lower control arms and shocks. Took care of the problem for me. Not sure what of the 3 fixed it. But it fixed it. I also run my tires at 42psi

    I don’t fly out of my seat but I do have a slight jolt, but it more so glides over bumps. I also have rear springs that are rated to carry 200lbs on constant load, with 295’s at 40psi. How fast do you go over bumps?

    New York roads are not the greatest so you can be on a highway doing 65-70 mph and around the corner the road is garbage. The rear suspension likes t dance to much. When installing my spring coils I was shocked to see how thin the rear control arms are, like coat hangers.

    You probably saw the sway bar links, there is no control arms in the rear. The rear links are pretty beefy.

    Are there not rear uppers?? Or am I losing my mind? It is my first 4runner.
