Intermittent clunking in front end

Warped brake rotor usually cause high vibration at high speeds. But you can also feel it at lower speeds. But bad ball joints and tie rod end will cause vibration at high speeds. Ball joints will pop at pot holes, sometimes. Tie rods can be felt in the steering wheel at a stop. Move the wheel slightly to the left and right, you can feel/hear a tap as you turn it.

check for loose steering box / rack. Check all steering ball joints and suspension joints. have a steering specialist shop check it out as steering problems border on safety

Here is the Technical Service Bulletin that maybe of help, worth looking into but can't guarantee that it would fix your problem Steering - Steering Column Clunking When Turning TECHNICAL Bulletin No.: 01-02-32-001P Date: November 25, 2009 Subject: Clunk Felt/Noise Heard From Steering Column, Steering Gear and/or Front Of Vehicle During Turning Maneuver and/or Steering Wheel Rotation (Replace Intermediate Shaft As Directed) Models: 2001-2004 Buick Regal 2005-2008 Buick Allure (Canada Only), LaCrosse 2000-2008 Chevrolet Impala 2000-2007 Chevrolet Monte Carlo 1998-2002 Oldsmobile Intrigue 2004-2007 Pontiac Grand Prix Supercede: This bulletin is being revised to add the 2008 Buick LaCrosse/Allure. Please discard Corporate Bulletin Number 01-02-32-001O (Section 02 - Steering). Condition Some customers may comment on a clunk type noise coming from the front of the vehicle while driving during a turning maneuver.
1. Locate a large area (parking lot) where the vehicle can be turned in a tight circle. 2. Turn the steering wheel to the right and/or left all the way to the steering lock, then off the steering lock a 1/4 turn. 3. Drive the vehicle approximately 5 km/h (3 mph) in a circle, preferably over rough pavement or seams on the road surface. 4. Drive the vehicle straight ahead at idle speed while applying and releasing the brake pedal. Listen/feel the steering wheel for the clunk/noise condition. 5. If a clunk is felt in the steering wheel, the MOST likely cause is the I-shaft - not the steering gear. Continue with the correction. Correction DO THIS - Replace the intermediate shaft DON'T DO THIS - DO NOT lube the intermediate shaft Replace the existing intermediate shaft

tie rod ends dry? this kind of thing is easily found if one person moves the wheel and the other listens and/or feels the different front end components. loud squeaks are generally accompanied by vibration which is hard to miss if you get down close to it.

When you put the vehicle in drive with your foot on the brake, and you hear a clunk. You may have a bad CV joint or axle. If not it may be a bad wheel bearing. Those would be the first two I'd Check. Outside of that sometimes poor wheel balancing or a tire belt separation. Either way it should be looked at before you hit 75+ mph. I had a Honda that I had just got off the highway with my wife and 3 month old daughter in the car. On a side street pulling away from a stop sign. The right CV shaft let go and dropped the wheel on the ground. There wasn't as much as a shimmy or a groan prior to that. If we had stayed on the highway another five minutes, I can only imagine. Please check it out for your own safety.

A lot of these Chrysler Town and Country vans had issues with the front stabilizer bar end links, usually you wont feel them move if you try to move them by hand, but they will make an awful noise clunk noise when turning or going over bumps slowly, i would suggest replacing the end links and that should take car of your clunking issue. Also the front lower control arm bushings separate as well and can cause this noise as well.... but i would replace the end links as a first step and go from there.... Hope this helps..

I strongly suggest you check the lug nuts for tightness and if they are ok on your right front tire then go to a tire service center and have them balance and check the belts-either is very dangerous because it will A-fafall off or B-blow at high speed. Good luck!

You may have a cv joint about to fall out.To repair this ,the whole axle will have to be replaced.Axle is about 59.00 at NAPA auto parts.But do check the play in the wheeel,jack the car up one one side in the front and then the other.Check the wheel,by hand grab the wheel on top,and the bottom,and see if you can move the wheel in or out,up,or down.Then check the wheel by doing the same thing,side ways.Grab the wheel(tire) on each side,and move it in,and out up,and down,and move it like the wheel is turning,to the right,and to the left.Do this all with the steering wheel locked straight.If there is any movement,look at where the give is in the steering parts,and ball joints,and bearing.Do this while moving the wheels.Then do the other side the same way.I hope this was helpful,please let me know.

check ball joints and tire rod first the clunking is a tati tale thet your ball joints are shot

Jack up the front end and put stands under it and block rear wheels. Look at axle boots and see if they are cracked. Try turning wheel back and forth sharply and see if you can hear any clicking. Problem could be outer axle joints. If the boots are cracked or you hear a clicking noise you will have to replace the axle. The axle and boot come as a complete unit. Please let me know what you find out.
