Propshaft center bearing DIY with pics

Remove plastic undertray for gearbox.
Disconnect O2-sensors(mark them before removal) and disconnect EGT(exhaust gas temperature sensor) if fitted.
If the car has a one piece stock system,the whole exhaust system has to be removed.
Remove the heat shield for the propshaft.



Remove the nuts(16mm socket) on the Diff flange (replace with new ones tightening torque 70NM),mark the joint to the flange and pull the joint loose on the flange...




Mark the guibo and remove the three bolts(21mm socket) of the propshaft flange(new bolts and nuts,tightening torque 140NM)






Remove the nuts(13mm,tightening torque 21NM) of the center bearing while holding it in place.


Lower the propshaft on the center bearing,pull it out from the guibo,then from the diff.Do not let the velocity joint go in a too extreme angle to the propshaft,it could be damaged.



Mark the positions of both propshaft parts to each other.



Remove the bolt in the cross joint that holds both parts together(tighening torque 97 NM,use Loctite high strengh for assembly)
Pull the halves apart.Remove the shim infront of the center bearing.
Use claw puller or similar tool to remove center bearing.



Clean surfaces,new bearing slips in by itself.Don't forget shim when assembling.
For the new center bearing the Terostat sealant against vibrations on the chassis should be ordered( see parts catalouge).



Assemble everything,time for a beer....

You need to update your DIY links at the bottom of your signature.

However some might start to say your signature is getting too long, but I think it is a good thing.

Thanks!

Will update this thread with changing velocity joint and the front bearing for the gearbox shaft in the prop shaft.
Ordered the parts yesterday and will tackle that down with pics next week.

excellent write up Vantaam, when i purchased my car the stealer told the old owner that it needed this bearing because of driveline vibes, and was quoted $500 for the labor, all it needed was a good wheel balance, so i saved 500
