 Subject: Stumped on a noise
IP: Logged
Message:
I know sounds are hard to describe, but here goes: I got a sound that is similar to a bicycle chain scrubbing against a piece of tin. It's sorta high-pitched. It echos loudly when driving beside a building. It happens when I apply even a slight throttle, then quiets when the engine torques back down. If I even tap the pedal, I can hear it loudly. Can't find anything loose yet. I've had a few shot-in-the-dark respones, but none that make sense yet. Anybody have any similar problems or solutions?

Sounds like you're describing a universal joint thats on its way out. Have it checked out, before you loose your driveshaft at an inopportune moment.

This a '00 4x4. The rear driveshaft has no play at all, but with the front, I can turn easily by hand about 2". Could the front u joints be bad?

I think they mean the drive shaft CV's.
I have had this problem, Have a good drive line shop rebuild it and put in the greasable points. I had mine rebuilt this way for about $250 painted and balanced.

If the sound changes with speed; like the faster you pedal the bike with the chain rubbing; a "U or CV joint" is a good bet. Don't rule out the tin heat shields above the cat, or attached to the catalytic converter. Those vibrate and can make one hell of a racket. A rubber mallet and 5 minutes of time will rule out a cheap repair.

The sound doesn't change with the change in speed. I checked the heat shields but didn't feel loose. I did remove one of the pieces that I thought might be the culprit, but I still have the sound. It really sounds like something that is scraping, or grinding. Thanks for the help, I will check the shields again.

Well, if you are so inclined, block the front wheels real good, jack up the rear end and run the engine. If it's there, it's not the drive train (2WD), brakes & tires. That rules out a lot of things. If you can make the noise happen with it jacked-up and have a buddy that is brave enough to crawl under, you might pin-point the problem.

Hope I'm not too late with this response. I just experienced exactly what you described. I have a 2000 Sport 4x4. I heard the noise you described as I was driving along-side one of the Jersey-Barriers on the highways here. I pulled my drivers side tire thinking to find the worst after reading the responses to your question (bad u-joint). Noticed that the Brake-Pad wear-sensor was cutting a groove into my rotor. About 1/8 inch deep. Sounded just like a bicycle chain dragging on a tin chain-guard. I did a brake job this morning, and was amazed at what I found. With only 22,000 miles, the passenger side pads were about 75% thick of the new pads. The outer pad on the drivers side, except for the corrosion, looked brand new...just as thick. The inner pad was paper thin. The inner surface on the rotor was also paper thin. Looks like that extremely stiff "spring" for the wear-sensor was affecting the way the assembly works on the drivers side - the inner pad was doing all the work. Both rotors showed signs of the surface material flaking off the rotor. Only 22,000 miles on brakes??? That is pathetically sad. I am currently looking to replace the Dak. Was thinking of a Ram 2500 diesel. But I've been getting VERY discouraged with the poor engineering of Dodge. I'm not so sure I want to spend $35k at a Dodge dealership now. Electric glitches, brakes, ball joints, etc, etc. Anyway, don't go replacing your U-joints that quickly. Check the condition of your brakes before you spend any cash on replacing those U's. Your problem might be a lot simpler, and cheaper, to fix.
