Suspension thunk - Help!?

[JKnippel]

I hope someone can share some helpful advice because I don't know where to start.

My '99 ironman has almost 70k and I replaced the shocks with rancho 9000 series about four months ago. Shortly there after I started hearing a thunk sound when going over harsher bumps from the front passenger side. There is no problem when turning (unless I hit a bump), so I'm not so inclined that it is related to CV joints.

Any similar experiences, ideas, or recommendations? I'm looking for some advice before I dive into changing CV joints, I haven't had the pleasure of changing CV joints yet.

Sway bar links?

i have had to tighten the lower bolts on the front shocks a couple times. i also have the rancho 9000 .the bushing in the front shock seems to be a little big ,and if the bracket is not tight against the lower shock mount it will make a noise.you should be able to check it if you wiggle the shock by hand. shawn

hey, got the same exact thing here with the rancho shocks on a 67K VX. This noise is really perticular, only happens on certain bumps and is definately coming from the front end like something is loose.

bump stops maybe?

it is the shocks. i had the same problem as stated above and tightened up the bottom bolt on the front shocks and solved the problem.i had to do this twice . i believe the hole that the bolt goes through is too big. shawn

Thanks guys!!!!!!!!!!!!!

I can't believe it. I went to go look at the shock, and the bolt had been sheared off!!. The shock was still in place though. I have since replaced the bolt and everything is all good. Thanks for all the posts.
