[urq] 4000Q rear axles

[Martin Pajak]

Hi Andrew,

Only the early 1985 4000 quattro with large one piece rear diff had the
large rear axles, same as '84 and Ur-q.
Mid 1985 they changed to small diff with smaller axle CVs.  Not sure what
the VIN is.
The axle might not be smaller, however the splines are different and it is
not possible to install a 110mm CV in place of the 100mm one.

Subject: [urq] 4000Q rear axles

I ordered a left rear axle for a 4000q and it arrived with a 100mm inner
joint. I am fairly to completely certain that all 85- 4000qs have 100 mm
inner joints in the rear. This is completely wrong in ETKA then, which shows
the same PN as the urq rears (108mm). Maybe the 1984 model had the urq 108mm
rears. My question is this, does 100mm mean that the axle shaft itself is
the smaller diameter one? Or were there thicker urq axles used with 100mm
inner joints on some model? Thanks.
