I have a 2002 4Runner that came with a Rough Country lift. Replaced the rear springs with OME 861s and Bilstein 5100 shocks. The Rough Country lift left the panhard bar at an angle. Not knowing this was not standard, when I installed the OME 861 springs and took a ride, I noticed the rear end was a lot more loose and floaty. I had noticed this when I first bought the 4Runner, but resolved that with replacing all the bushings in the rear and replacing the rear end links with front end links. So, having resolved those issues, I wasn't sure why I was feeling this again, although less than before. Additionally, going into a curve I drive daily at a certain speed, now the traction control light and beeping comes on often, but never did before on this curve.

FWIW, I bought the OME 861 springs because one, I am not a fan of Rough Country and two, after loading the rear end with a Shrockworks bumper, a spare 33" tire, a high-lift and 2 Jerry cans, it leveled out the rear. But when I would load it with gear, the rear sagged a bit.

Anyway, I am really happy this post helped me to figure out why the rear is acting the way it is. I just bought these @eimkeith Looking forward to getting them welded on.
