Driveshaft noise

[purplecty]

Driving my shorty sport home and when i got off the highway i noticed a metal clicking noise coming from under the car intermittently as i accelerate. I Hear lightly it also when letting the car roll. What can this be? CSB? Cv joint?

Kind of like cleo

Anyone have experience with this?

Rear CV joint - and fortunately one of the few bits on the propshaft that you can replace

[purplecty]

Thanks Timm! So definitely recommended to replace the CSB and flex joint (guibo) While its apart?

As always do as you feel is best. Although more expensive I believe it's more cost effective to change out the entire shaft assembly. By the time you remove the exhaust system , heat shields, etc. With the new shaft it's one and done. it may be the CV, even if you change the Guibo and center bearing, it's good practice to change the centering sleeve and you still have old "U" joints. With a rebuilt assembly from somebody like Beyer, you'll have a new centering sleeve , Guibo, center bearing, replaceable "U" joints and CV with gasket all balanced, ready to go. Throw on a new transmission mount and you're rolling.

Wait, what? It comes with all these parts or are you saying to add the drive shaft to my list of parts?? And the u-joints are replaceable? Link so I can see cost?

It was my experiance when this happened on my 750 that I dropped the driveshaft down, cleaned all of the old, dry nasty grease out of the end of the drive shaft where it connects to the rear end. Then packed it with fresh grease new gasket and no more noise. Everything else was perfectly fine.

Beyer is one of many rebuilders, I had good experience with them.

Drove it to my buddys garage and on the way it had a nasty vibration on acceleration which to me would be the CSB. I ordered the cv joint, csb and guibo(flex joint).

I think it's a Cross Joint

Whats a cross joint?

I had my propshaft rebuilt few month ago. All together ~300€
All parts new, new U-joint. But CVJ is old, as it was good, they tested it on balance machine and everything was fine.
My U-joint was sticking in the center, like its stuck, new one is moving free. Shifting improved, and from P to R or, D to R is very soft.

Make sure you buy OEM CVJ, I bought aftermarket and it was 4.5mm too long on the inside, so I couldnt lock it in place on driveshaft with that little lock ring.
Oem was 24mm, aftermarket part 28.5mm.

this, one of 4 bearing/ends fall apart

Im pretty sure you can replace the Ujoints in our driveshafts. I ordered an genuine BMW CV joint.

The Ujoints are peened in place, so you need a special machine to remove them. Some of the rebuilders make the U joint removable for the future. I used Texasdriveline, they replace the joint in the OE manner.

It must be replaced with knowledge and special tools, it is not take out and replace.
Mine was,pressed in, then it was welded in place by local cardan shop.
But pretty simple job it is, then propshaft needs to be balanced as a whole unit.

Thanks for the info. Didnt have time this weekend to do this. Probably next weekend. Parts are on their way...

[NordmanMg]

Purp, parts will not help if you not gonna replace X-member/joint, and only machine shop can remove and replace it, because technically it's one way part, which had to be replaced as one whole part with drive shaft assembly

[purplecty]

Im not replacing the U joints. Im going to do rear CV joint, csb and flex joint on front of driveshaft

[purplecty]

Issue was rear CV joint. Replaced this plus CSB and guibo...

good work, way to go!

[purplecty]

Seemed that the grease hardened up and overheated the cv joint. My buddy noticed some play in the center u joint, but at this point im not too worried...

[Chief Jimbo]

Yep yep!! glad you got it fixed. Mine did not overheat too much so I was able to clean it all out and repack the bearing.

Need to replace the trans mounts (I have them burried somewhere) and appears to have a small output seal leak in the trans as well...
