    Default doing flex disc and centre bearing tomorrow. any advice?

    hey guys, bought me a flex disc and a centre bearing/mount today. flex disc bm calls artic disc?

    Anyways, I have the bentley pages at the ready and father in laws garage at the ready. What are the lurking evils if any? its looks pretty straight forward to me but id like to hear of any experienced efforts.

    What else might I have a look at while I'm there? thanks in advance.

    Best info is on Johan and Sean's E32 page. Good write up on that.
    Link is on my website below.
    Pre-tension of the center bearing is very important.

    1 - good time to replace your exhaust donuts or have some spares on hand.

    2 - if you undo the exhaust at the manifold, a) spray the nuts slightly with some pentrating oil and b) run the nut forward a 1/4 turn before you back it off. somewhat easy to snap off the studs.

    3 - great time to rebuild you shifter linkage. did I say great time? REALLY great time. you are all the way in there. expect to have to order the parts. search the archives as some good lists have been posted.

    4 - wanna shorten your shifter throw? order up a z8 shifter arm for about $55 and swap that too.

    5 - the guibo is easy. the center bearing can be a trick to remove. a gear puller can be helpful to pop it off.

    6 - got a 535? be sure to be careful with the rear cv joint. it will be exposed when you drop the driveline.

    ok..that's I can think of for now. have fun and good luck.

    Jeff's talking about a manual gearbox, which you don't have.
