View Full Version : can the e34 CV joint be relubed WITHOUT removing the whole shaft....

more specifically, bentley says that the joint must be pressed in and out. is this something that could be accomplished with the other joint remaining on the car, ie, by hand or with a puller? i'd rather not have to crack all of those 75 lb ft hex bolts just to take the boot off.

I have just DIY'd my cv joint rubber boot replacement 3 months back and I did have the whole half shaft removed off the car.I suppose you can do a re-lube of the CV joint in-situ if you want to.Just loosen both the metal clamp ring and slide the whole boot towards the diff.Best to have the tyres suspended so you can give a thorough cleaning of the cv joint ball bearings.

it's generally good practice to leave em alone unless the boot is torn, it's just not a part that normally wears out on bimmers, yes it's a pain to replace the boots i get good practice on 850 volvos, they suck ass and split all of the time

the only reason i'm contemplating doing the boot is because the cv joint has begun to moan at certain speeds, and i'd rather not wait for it to die (if it is indeed) lack of lube that's making it sing. thought it was a wheel bearing at first, but it only occurs when the gas is applieed, and it doesn't make the noise in coast. the boot is in remarkably solid shape, though. i have to do brakes next weekend, i might just slide the boot forward, see if the grease is dust-ified or not, and if it is, clean it out and shoot some new stuff in there. do you have any idea as to how long i likely have left with the joint in such a condition?

redline synthetic in it and it will quiet right down.

moaning......differential.......

i thought it might be the differential, but the problem is is that its only groaning on one side of the car, and its not doing it when turning (only in straight lines). is the diff compartmentalized sufficiently to have worn out fluid cause a noise on only one of the two wheels?

noise and it usually only does it in straight line. Usually more noticable at 50 mph and above, typically the faster you go the louder the noise is as the diff wears. And by giving it gas the noise is there, but when you back off and coast just right the noise will go away. I don't know why you would hear the groaning only on one side of the car.. I wouldn't really describe the diff noise as a groan its more of a whine to me.

i only hear it when seated up front. i rarely ever ride as a passenger in my car, so it sounds like its coming from the centre back-->passenger area. it might just be coming from the centre, never considered that. i rode in the backseat whilst my uncle drove to niagra on the lake, i couldn't hear the nose at all. will the mobil 1 gear oil work instead of the redline, as i have two bottles of that sitting here unopened. was gonna change it when i relubed the cv joint to make sure everything back there was in order. i guess if i had done that, i would have assumed that relubing the cv joint was the solution to the noise instead of the fluid change. oh well, ill peel back the boot when i do brakes next week, if its severely dry, i can just clean and shoot some grease into it.

if not diff dieing wheel bearing?! it's a bitch to tell early on sometimes

if it was a wheel bearing, wouldn't it likely be making noise when power is engaged AND disengaged? that's why i thought it was a cv joint, as i could never get it to make the noise when coasting.

Bringing this back up, did you figure out what it was?

I've got a clicking coming from the back end, 90% sure it's the CV joints but want to see what (if anything) you found out .

there was no differential noise or cv noise in my case. the pair of tires i had on the rear wheels were just noisy. noise moved to front when they were moved to the front.
