Hi,

I'm putting a '89 auto trans Wolfsburg back on the road. I am planning to
change the drive shaft seals for leakage and noticed that there is a
noticable amount of side and end play in the out put flange.Is this normal
or is this from some wear in the diff bearings? I am going to pull the pan
to change the oil and see inside and can check better if these bearing are
loose. If there is some looseness but no significant metal in the oil
should I tighten them up by adjusting both sides equally? Is there
something else that would cause this looseness?

The Bentley calls for SAE90 oil for the final drive, what is the current
recommendation to use here? Is an 80W-90 GL-5 good. I have some Redline
MT-90 that I probably bought around '06, would this be a good choice?

I didn't find anything in the archives on these subjects, but maybe I
didn't search right.

Thanks for any input,

Ray
