Drive shaft blues

[CAM]

Hi guys,

I've changed all brake hoses on my '75 european 2002.

But, for the rear hoses I couldn't get on the bolt at the rear axle side.

So, I dicided to lower the rear axle 15CM and I could reach the bolt.

I did this on both sides, but the result now is a lot of noise/vibration coming from the drive shaft when accelerating, especially in 3th and 4th gear.

Before this operation, I didn't have these vibrations.

The repair CD talks about "..injecting Loctite Green in the sliding section of the drive shaft...".

What did I do wrong?

Who has been there?

Friendly greetings,

I haven't got a sliding driveshaft, but how did you lower the rear axle & if you did it just to reach a bolt, why not put it back where it was ? Or maybe I misunderstand and you did put it back up. You had no vibration before, so alignment must be critical. Otherwise, I'd say check the center support bearing for tears in the rubber, & make sure the nut that holds the 2 halves of the driveshaft isn't working loose causing play.

It could be that by moving the rear end you have changed the way that the driveshaft is putting pressure on the center support bearing. There are specific instructions about where to line up the center support bearing in the manual...

I don't remember the specifics, but you are supposed to preload the center support bearing in one direction or the other by a specified amount, that's why there are slots for mounting it instead of holes.

Also check the total preload from the differential by loosening the 6 bolts (4 on the bottom, 2 on the back) and then retightening them all to be sure the driveshaft isn't being squeezed or stretched.
