Hi John!
I recently had a ball joint replaced, and the guys at the shop tell me
the real struts and mounts need replaced. Better than $600, mostly
parts.
This seems possible, as once in a while the rear end is a bit clunky.
But struts are easy to replace, aren't they? Is this a home job?
Are mounts an automatic replacement?
On the 99 OB, the rear strut is a "coilover" design. I'm assuming that
what you are calling the "mount" is the strut top, which does not come
with a replacement strut. This is probably the source of your "clunk".
While this is not a terribly technical job, it does require at least a
spring compressor, and a heavy duty impact wrench. The lower fasteners
can be very tight, and you may need to remove the rear brake calipers
as well. Also be careful with the ABS wiring.
I'd suggest that $600 isn't too unreasonable, assuming that the price
includes both strut cartridges, strut tops, and labor; I'd imagine
that it is at least a 3 hour job, and the components aren't
inexpensive. The KYB replacement cartridges are popular.
Another good option (especially if you elect to DIY) would be to find
a good set at a salvage yard; then you won't have to disassemble the
strut, just bolt on the replacement.
ByeBye! S.
