DIY: Driveshaft Rebuild/Repair
 
I had picked up a Driveshaft for $100 at a junk yard that needed a little work. Flex Disc aka (Guibo) was torn to shreds. Center Mount was falling off and center sleeving well lets just say didn't look to good. Anyways in the midst of still waiting for a new clutch kit and SSK I decided to post this write.

Tools Needed:

Dremel w/Grinding Bit
Snap Ring Pliers
Rubber Mallet
42mm Open ended wrench or large Cresent Wrench
18mm Wrench and or sockets
3 jaw puller
Grease

Parts Needed:

The only part that will vary from auto to manual is the flex disc this one however is for a manual. (the difference being the autos is slightly larger)

Flex Disc - P/N# 26111227410 - FREE for me since it came with the tranny I bought
Center Mount - P/N# 26127501257 ~ $26 @ www.autohausaz.com
Centering Sleeve - P/N# 26117526611 ~ $10
Clamping Sleeve - P/N# 26117514037 ~ $10
Circlip or locking ring (whatever you want to call it) - P/N# 26123648156 ~ $1
Butyl Tape - P/N# 26127511140 ~$3 (However this is for when you reinstall the driveshaft on the car, for some reason my car didn't have any when I removed my autos driveshaft, but I'm gong to use this anyways.
3 - Hex Nuts - P/N# 07129900047 ~ $0.50 each
3 - Hex Bolts - P/N# 26117523709 ~ $2.00 each

Step 1:

Remove Flex Disc aka (Guibo) When I bought it (The driveshaft) it was literally torn to shreds so that thing needed replacement. Well it's only held on by 3 - 18mm Bolts and Nuts. So whip out your wrench and socket and remove them. Supposedly I think the bolts are one time bolts, so I bought new ones anyways just to be safe.

Step 2:

Since my centering sleeve was not looking so good I decided it needed to be replaced. BMW apparently doesn't give a time frame on when it should be replaced. But I have a feeling the people at the junkyard didn't know how to remove the driveshaft. For when I removed my automatic driveshaft my centering sleeve looked perfect.

Anyways I had originally bought a small 1/4" to like an 1" bearing puller to pull the centering sleeve out. Well that didn't work and the puller broke an arm. So I took a dremel with a grinding bit and carefully ground away at the centering sleeve until it came out.

This stupid thing broke:

Step 3:

Seperating the driveshaft, make note of the two white paint marks made from the factory on the driveshaft. You are to reconnect the driveshaft using these as reference. If you are off even one spline, it could result in an unbalanced driveshaft. If there are no marks or white dots then make your own marks.

http://www.jdmotorwerkes.com/Tranny%...1/DSCF0625.JPG


Loosen the clamping sleeve, it's about 42mm but I just used a Large Cresent wrench, plus the torque spec is really really small. One clamping sleeve is fully loosened you can seperate the driveshaft.

Old one on the right and new one on the left:

Step 4:

Remove the Lock ring holding the center bearing of the center mount in place. Use your lock ring pliers to do so. Next you can now remove the center mount with bearing. Since my mount practically crumbled off I just needed to remove the bearing. For this I whipped out my trusty 3 jaw puller which did the trick nicely. Apparently some people say you can "supposedly" remove the bearing by hand. Honestly I don't think thats possible since the thing is pressed on.

I know I know I used a screwdriver in this picture but lock ring pliers would have been easier:

Step 5:

Once everything is removed, cleanup the driveshaft center sleeving are of all the metal shavings, clean the splines free of grease since you will be reapplying new grease.

Step 6:

Installing the centering sleeve, simply apply some grease to the hole the sleeve will rest in. Now put the centering sleeve in the hole, it will need to be pressed in, well thats where your trusty mallet will come into play. The center sleeving is suppose to protude the slot 4mm. So in order to do this you must hammer the sleeve in with your mallet and keep double checking the measurements untill you get to or pretty damn close to 4mm.

Just bout right:

Step 7:

After you installed your center sleeving you can now move onto the center mount. The one you ordered should have already come with the bearing pressed into the rubber mount. Apply some grease to where the center mount will go. Once again his will have to be pressed on, and will be a little harder because you don't want to damage the bearing.

http://www.jdmotorwerkes.com/Tranny%...2/DSCF0096.JPG

I made a device out of pipe and a tranny input shaft seal I had lying around. The tool I made rested perfectly against the bearing and rubber. Now put your tool to the test and use your mallet again or you can use a 3 lb hammer and give it a few light taps to press the bearing on.

http://www.jdmotorwerkes.com/Tranny%...2/DSCF0105.JPG

http://www.jdmotorwerkes.com/Tranny%...2/DSCF0106.JPG

Note: that where you removed the lock ring clip there is a small groove in the driveshaft. DO NOT press the bearing past this point just enough to reapply the new lock ring, I don't know if there is any detrimental affect, but I just wouldn't chance it thats all.

Step 8:

Reassembly of the driveshaft, apply grease to the splines and put on the ew clamping sleeve you have purchased, I'm sure you can use your old one but I just decided to go with a new one. Realign the driveshaft according to the white factory paint marks. REMEMBER IF YOU ARE EVEN OFF ONE SPLINE YOU WILL MAKE THE DRIVESHAFT UNBALANCED. Slightly tighten the clamping sleeve but not fully until you are installing the drveshaft back onto the car.

Step 9:

Last Step, now reinstall your new flex disc aka (guibo) using the new Hex Bolts and Nuts you ordered. Using a 18mm wrench and smaller breaker bar with 18mm socket this can be easily done.
