I have a 1999 jeep wrangler and when I hit a bump there is a load knocking nose comeing from the right front tire area.

I have the same problem few days ago, and still didn't find any solution. Can any one please help?????2

Dodge is known for using rubber bushings in everything. They don't squeak like the poly ones do but they do rot after 10 or 15 years and cause clunking noises like you described. More than likely your clunking is coming from a tie rod which is what connects your steering wheel to your tires. Crawl under the truck near the wheel and look for the steel bar that hooks up to the back of it. Have a friend turn the wheel back and forth, or grab the bar and give it a hard shake. If there is any play, the bushing is shot. You can replace the tie rod ends yourself using the old ones to compare but it will still need an alignment, so I usually let a shop do it. New poly bushings will cost a little more but you will never have to replace them again. A good alignment shop should charge less than $200

try changing the tires . you may have a broken bead in a tire, which flattens when you hit higher speed.

Most likey it is the brakes.

could be a bent rim ? have you changed the universal joints? how about the tie rods and stabilizer bar

If it is new take it back to the dealler for warranty repair. No new vehicle should have any noises . seriously, take it back for repair.

Shocks are usually pretty much shot after 45-50K. Also check damper (sideways shock on steering linkage). Shake is either wheel balance or a worn steering component (should have been checked before alignment...shame on them if they didn't)

HAVE YOU CHECKED THE BALL JOINTS ? jack it up and raise one of the wheels off the ground putting a bar under the tire raise and lower the bar to see if there is movemement in the ball joint..

It could be the steering rack but the first thing you should do is have an alignment job done. Even if there is another problem, the hit would almost certainly knocked your suspension out of alignment. So you'll probably need to get this done anyway. If there's still a problem after that, then I'd have your steering looked at. But the alignment may fix it entirely.

Hay I would check your sway bar in the front .The bal may have came out of the seat located under front wheel well. Also they could be just loose. Check by rocking your jeep side to side .
