I replaced the rear springs and shocks in my 1984 Audi 80 quattro last
weekend. The strut bearings were ok, however, the wishbone bushes
were beginning to fall apart. I also could feel a bit of play in the
large ball joint at the end of one of the wishbones, but I couldn't
afford to replace this at the moment.
I bent a 1 ton vice trying to press the wishbone bushes out and finally
resorted to pressing out the internal bits of rubber and metal, but
leaving the outer metal shell - then I hacksawed two full-length
grooves along the metal shells taking care not to go through and scar
the wishbone - then I used a hammer and punch to fold and tear the
shell and finally pressed out the remains quite easily - if you have a
10 ton press and all the appropriate tubes and washers, this job would
probably be quite easy.
I also found that two rear diff rubber mounts (the ones at the front of
the diff) were in a bad state - one of them didn't have any rubber
left in it - that explains the loud bangs I've been getting on
changing gear. These were very easy to replace. I didn't replace the
rear mount - I would have had to remove the rear diff - not that
difficult probably, but I would not have been able to press the old
mount out anyway. I couldn't see it very well, but it didn't appear
to be showing signs of wear.
The new shocks (Boge Turbo Gas) are really nice.
My diff lock (centre) now disengages without me needing to go into reverse.
I need an alignment - the car now pulls to the left. I took great care
not to disturb any of the settings for castor (or is it camber) and
toe, but obviously the new springs/shocks have a different geometry.
I am still getting some small rattles/clunks from the rear - anyone any
ideas - I thought I had replaced/checked everything.
>4) What kind of gas mileage should I expect?
I get 30 on long trips and 25 on short (5 mile) commuting.
