Drive Shaft issues

[Googleme]

First off wanna start with a big thank you to all that contribute / help.

Hey guys, my car has the violent shaking under the car issue. It's actually been behaving recently so i've put it off but now that i've got a little cash i'd like to get it fixed.

Took it to a mech and got it diagnosed for $97 but heres the catch. The mech wants to order new oem parts at some stupid overpriced amount + labor. In total he wants $400 but he's willing to subtract the 97 for the diagnosis if i let him do the work. So, how easy is it to replace the flex disc (guibo or whatever its called) as well as the center support bearing myself. I can find a guide on how to do it but I'm just wondering if its really worth it to do it myself, or just pay the mechanic the $300. (ive already paid the 97).

I was thinking I could try to do it myself and maybe use that 97 towards something else but idk what that would be. After all isnt that the point of having an e30? you dont need a mechanic? lol. Since this is probably one of the harder projects im thinking ill throw the mechanic the bone.

dont worry, ill keep my ego alive my constantly reminding myself i coulda done it myself if I wanted.

Both parts are easy to replace. There's 6 19mm bolts on the guibo and two 13mm bolts on the CSB. You'll need a press and some circlip pliers to take the CSB apart too. Not a really difficult job with a press, but it can be done.

awesome thank you. I have jack stands and even tho they arent that high i think i can manage.

I was actually more concerned about taking the drive shaft out rather than the actual work with the parts. I hear taking the drive shaft out is rough.

In almost all cases, a failure of the center support bearing will be caused by binding u-joints in the driveshaft. Replacing CSB is a waste of money and time as it will soon fail. The only real fix is a replacement drive shaft. A rebuild usually comes with a new CSB installed. Those from DriveLine Services have a good reputation.

IF you choose to remove the driveshaft yourself, it will be best to mark it's orientation before removal.

this is the most important part, otherwise it will vibrate. The two halves need to go back exactly how they came apart.
