No clicking as such. When accellerating I can turn slightly right and
off the driveline and the shudder will reduce.

With the car in drive (auto tranny it is) and standard dead still there
is a bit of rumble going through the car. Could this be put down to the
CV joint or would the rumble (absolutely nothing compared to the
accelleration stuff) be from a possibly warn engine/tranny mount?
Would a warn inner CV joint that causes such shuddering also play
havoc with the steering? I can be driving along and the wheels will
decide to go opposite directions, so it will be a bit of a fight to
hold the car in line. Supposedly the steering thing could be my warn
shocks. (Damn, does anything work or last on my car?)

The NAPA people stock lots of the stuff. I'd probably just grab any
make, not that I'd be the one to pull the CV joint and do the work as
I don't know what tools are needed and how complex the job might be
for my little, impatient brain.
