[urq] Audi Axle Lengths Question

[Martin Pajak]

Hi Pat,

There is a solution, for you European guys at least.
Starting 1986 Ur-q used 82mm bearings in front.
You can use the 1989 and up 200q10v hubs (same offset as Ur-q) and larger
82mm bearings.
The S2 shafts will fit the 200q hubs.
That is the only way I can think of to make the Ur-q stock with proper
looking one peice struts and be able to use S2 shafts for 01E without any
spacers, cutting or welding.

Hope this helps.

Cheers
Martin Pajak

To my knowledge there  is no bolt on solution for this , except to use the
entire front suspension , subframe and driveshafts from an S2 .

For the other typ85 quattro's it is possible to use later coupe or 90 7A-20V
driveshafts .
The type 85 CV joints magicly fit . Helas , the ur-q CV joints do not . .

The only small chassis car that has the beefier axles of the right lenght
for a 01E conversion is the (R)S2 .
But then the outer cv joints don't fit the urq hubs , the S2 hubs don't fit
the ur'q bearings , the ur-q cv joints don't fith the S2 shafts .
I've tried it all . As far as I know , there 's no combination that will
work without some degree of machining .

Best options are to modify S2 hubs to make them fit the urq bearings and use
S2 driveshafts .
Can be done on a lathe , it's not even that hard .
Or as you suggest use a short axle and machine some kind of shim .
Theasme has to be done to the centre driveshaft btw , btdt a couple of times
.

I'm a pretty decent welder myself , and cutting and rewelding a driveshaft
would scrae me to .
Not for the lack of strength , but for balance .
The slightest warpage will cause vibrations .


Good luck

Pat
