| I have a 2001 GMC jimmy. I have changes the shocks, Hubs and back brakes since owning the truck for a bout a year. I was off roading and put the truck in 4x4 and I heard a loud snapping type noise and later a high squealing noise near front tires. Now when I start to accelerate a rattling clunking noise is heard near the front (middle) of truck. It goes away sometimes but can be heard when driving lower speeds durning acceleration. I went under the truck and turned the drive train. It seems to make a low rattling noise at the end closer to the back where the U Joints are not. Any ideas if this is a u joint or a new drive train will be required? My truck also makes a squealing typ noise when the wheels start to spin but I think that is my wheel bearings and nothing to do with the other problem. Please help | |
Let me start by saying my mechanic is a family friend. Sometimes thats a good thing, sometimes not. In this case, I'm not sure. My antilock brake light came on, and he replaced the front hubs as the wires were worn. Light went off, all was well. However, driving it home, when I did a hard turn (left or right), I hear and feel through the floor a clunking sounding like it was coming from the front right. I went back and he said it was the CV. Replaced that as well. Guess what? Still clunks. He super greased the upper and lower ball joints, clunk clunck. Now he's telling me its the control arm/control arm bushings making the noise. Does this sound right?? Any suggestions would be greatly appreciated.

My 98 4WD Jimmy which just turned 200k is developing a rattle only when I accelerate. It doesnt rattle every time I press on the gas - and sometimes when it does rattle releasing the pedal and pressing on it a couple times makes the rattle disappear. The rattle sounds like it's coming from under the middle of the vehichle (but I can't be certain). It doesnt rattle when I go over bumps, but when I reverse I get a rear end clunk (typically only once during the reverse). Not certain these things are related. During last oil change a mechanic told me my rear differential was starting to go - but I could probably continue driving on it for now. Are these noises related to that or seperate? Thanks!

The rattle noise could be your catalytic converter. Have someone press the gas while in park and look under vehicle and see where the noise is coming from. If the rattle is coming from inside the cat, then have it replaced. The clunk noise is probably a u-joint going bad. |
