Isuzu Trooper Steering Stability Suspension

jsintexas

I have a 1989 isuzu trooper that i keep on the ranch full time. The front suspension is real squeaky and loud--- everytime i hit the slightest bump or turn the steering wheel it scares off everything within a 2 mile radius. Basically, the trooper sounds like a tank traveling down the road. I tried spraying lithum grease on all suspension components as well as using wd-40 (2 cans, one for each side of trooper). ---no luck. I'm guessing it's the cv joints under the rubber boot, or possible defective shocks. Any advice would be greatly appreciated. thanks---JS

I don't have your model Trupr, but generally, if your control arm bushings are worn, or your shock bushings you will get a noise on a bump. Unfortunately, bad ball joints can also make noises as well as front wheel bearings.
I guess what I am trying to say is that you should check the easystuff first....like the sway bar bushings and end links, then have someone bounce the vehicle while you listen and explore the source of the noise you hear. I would look for a bad shock (you have to look at the bushings in them, not just see if they are tight), bad ball joint(s) (jack up front and them use a lever to pry up on the tire when if is off the ground and look for any movement in or out), and then the control arm bushings (pretty much same as ball joint only look at upper and lower control arm bushings.)
CV joints will usually give you feedback through the steering column as well particularly during a turn...ie: clicking and popping and shuddering. Assuming you are in 4WD and hubs locked.
Good luck hope this helps.

Do you have sway bars? The sway bar bushings can get noisy especially after market stiff ones. The good news is that sway bar bushings are low cost and easy to replace, easy enough to do it just to see if the noise goes away.

Has anyone replaced the Trooper shock absobers lately, and/or have any good recommendations?
A buddy who has had many trucks (but not a Trooper) recommended the Rancho RS 5000. I see that KYB also makes at least two shocks that fit a 2002 Trooper.
Will be used primarily on-road.
Appreciate any insight.
