A buddy was in my 4Runner last week while we were on the freeway and commented that my truck seemed to have a rear end 'wag' as we were traveling. I guess I had never noticed it since I drive it every day. After he mentioned it I started noticing it a lot at freeway speeds. When I would go over a rise or something, the rear end would sway side to side (or wag the butt) Almost feels like a shock maybe shot (would have to pull them out to test I suppose) Anyone have similar experience with this? I have the Bilsteins installed with abt 80k on them. Do they have a warranty? If they are indeed shot and the cause of this problem, any recommendations on what I should replace them with? Same? Better options? best bang for the buck? Thanks!

There was a recall on 3rd gens for a similar problem, did you have that done?

And are you lifted? A lift angles the pan-hard bar so that the rig moves more side to side than when it is level. A panhard mount drop will help improve that.

No lift...just had the trd bilsteins installed at purchase.

I'm not familiar with the recall....please expound!

Actually the recall was on 96-98 4Runners and updated the rear suspension to the newer 99-02 type, so that wouldn't affect him.

The Bilstein shocks are supposed to have a lifetime warranty , but I don't think shocks would cause this. What I would do is jack the truck up and put it on jack stands. Grab each and every one of your links on your suspension (2 upper, 2 lower, 1 panhard bar) and also your sway bar and endlinks. Basically, just check everything for play. Check the shocks too. Maybe unbolt them from the lower mount and try to compress them and see if they are equally pressurized.
