SOURCE: i hit a bump on

Sounds like your left front wheel bearing is going bad. When you make a right turn, or compress the right front suspension over a bump, it forces the car to roll to the left. This loads the suspension on the left side, which will exaggerate a wheel bearing problem. Are you hearing the noise at all when travelling on the highway in a straight line? If so, it'd be either a grinding sound or a hollow humming noise. If you aren't, it may be that the bearing is just starting to go bad.

A quick test to see if the bearing is bad is to jack the car up at that corner, grab the wheel at the top and bottom, and shake it hard - if there is any movement or looseness, your bearing is shot. If there is none, it doesn't mean the bearing is fine, but it could be that it's just starting to go bad (which would be why you only hear it in turns and bumps, but not straight-line yet).

2003 Chevy Silverado is making a clunking noise, on and off sometime over bumps. Also a deep grinding type noise in the same location while driving not constant


Hello Karla,

It sounds like you may have a bearing or CV joint going out. Your vehicle will need to be jacked up and inspected. It may be more than one problem too. Its possible the dragging noise could be something between brake pads and rotor, but the grinding that comes and goes in reference to direction sounds like a bearing or joint. I would take it to a professional right away and ask for an estimate only, and then get other estimates from other shops as well. Good luck to you.

Just replaced doesnt eliminate the intermediate shaft, could have been a defective part or poor installation. Other then that, it can be as simple as a sway bar link and or frame bushings

Clunk noise from front passenger side when


That noise sounds to me like a Ball Joint problem. I would check to see if you have fittings to grease the front suspention.

Good luck, Allen

2002 chrysler mini van front end noisy .when you hit a bump.what


I had the same problem with my 2002 Town and Country Limited. I took it to the mechanic and had the sway bar links and ball joints replaced and still had the same clunking noise when going over bumps at low speeds. The van sounded great on the highway, but country roads were horrible. I was about to replace the struts and pay another 700 dollars when i read somewhere that the sway bar bushings could wear and cause the noise. I took it to the mechanic and he said absolutely not it would be a waste of money. Being the stubborn guy I am, I went to NAPA and bought the two bushings for 12 dollars and replaced them myself in an hour. I took the van for a test ride and the noise is completely gone. Please ignore your mechanic and replace the bushings ASAP! Pretty cheap try even if it doesn't work.

Transer Case; 2003 Silverado, Z71/4x4 (NP246)


Check to see if you have a pin hole leak on the passenger side of the transfer case, it will be blue in color, it is caused by a PUMP RUB issue that Chevrolet refuses to acknowledge. It will be located the 5th. bolt up from the bottom, you may be very low on fluid. For an easy fix, clean and grind slightly and place JB weld at the hole. Let me know if this is the problem. I used this technique on my 2003 avalanche and it has held for 8000 miles with no reacurrence.
