Has anyone ever had a universal joint for the power
steering wear out.  Mine seems to have play that
produces a knock or mild clunk when the steering wheel
is rocked back and forth.    I think it's from all
those thousands of miles of bumpy dirt road.  (This is
on a syncro)

And what about the "Relay Steering Gear" as it is
called by VW...the box where the steering shaft comes
in from the steering wheel, and then exits at about a
50 degree angle on to the power steering rack.  Is
there any maitenance for this ?  Do they ever wear out.

Aside from the PS universal joint, i am going to
replace the three steering couplings...unless someone
tells me this would be a waste of time.  Any other
steering parts/maitenance I should take care of while i
am doing this?
thanks
