Posted December 7, 200519 yr comment_148341 Only when the clutch is engaged and accelerating especially in first gear. The further up the line of gears I go the less the noise.So...car in first gear, pull out , sounds like the noise is coming from the left rear wheel, a sqeaking sound like something needs to be greased. Shift to second the noise lessens, third , less and fourth almost totally gone. Its loudest in first gear.If the wheel is rolling on its own and not under a load from accelerating the noise is gone, only when you give it gas does the noise start ( the squeaking sound) almost like something is hung up on the wheel , but its not , have checked the pads , no problem. Any help will be greatly appreciated. Right now the only thing I can think of are two things, there is a grease fitting on the lower side of the wheel or its coming from the differential, Im totally lost pretty much.

December 7, 200519 yr comment_148362 a sqeaking sound like something needs to be greased. Hmmm, could you describe the squeaking a little more?Does it sound like it only squeaks at one point in the rotation of the wheel?Or, is it a constant squeak?What year Z do you have? Do you have drums or rotors in the back?Where is this grease fitting?One thing I can tell you it's probably not. A bearing. When a bearing goes bad it usually has a "grinding or rummbling" noise. The same with the gears in the diff.

December 7, 200519 yr Author comment_148366 Constant squeak as the wheel rotates, not like squeek , no squeek , squeek as in when something is rolling and only making noise in one area. Like squeek , partial rotate , squeek, partial rotate , squeek ( as the wheel is turning ) Drums in the back, its a 77Grease fitting is on the back side of the mount for the wheel, at the end of the axle below the strutIts not a grinding or rumbling , just a loud squeek like when the wheel rotates and it would be off and on as the wheel turns, but this squeek is constant as the wheel is turning, but only when the car is in gear and pushing down on the accelerator, if its coasting , it doesnt squeek ( in or out of gear) its like the clutch has something to do with the noise , but its not the clutch.The brakes were changed the last week of July or the first week of August and it took until the 3rd week of Nov for the noise to begin.

December 7, 200519 yr comment_148368 Sounds like u-joints in the left half shaft to me. The fact that it only does it when torque is applied means that's about the only choice.

December 7, 200519 yr Author comment_148370 Ok , now what do I do , how do I fix the problem, do you have to replace the existing U-joints or just what do I do if that is the problemThanks Link to comment https://www.classiczcars.com/forums/topic/18241-noise-from-left-rear-wheel-only-when-in-gear/#findComment-148370 Share on other sites More sharing options...
