[Vwdiesel] Vibration under load (hill climbing) and improving cornering

I'm doing better with my hill climbing now that I'm downshifting earlier
(by 60 mph). Temps are staying a little lower and I'm getting up the
hill faster. It helps to get a running start, so I get irritated when
gas guzzling SUVs won't get out of the way. (If I hit the bottom of the
hill that climbs 600' in a little over a mile going 70 mph, downshift to
3rd by 60mph, and keep it floored I can make it to the top still going
around 48mph with about a 2 line increase on the temp gauge. (1.6NA).
Anyhow, when I'm climbing at full throttle if the road curves to the
right I get a vibration that feels and sounds like the right front wheel
is wobbling. On left turning or straight climbs or cruise, it's smooth.
Lane changes at cruising speed on the highway can start a similar effect
(the end of a change to the left or the beginning of a change to the right).
For convenience I've been having my oil changed by a VW shop and I
mentioned it to them several months ago and though they took no test
drive the mechanic said (after yanking on the wheel) that the right
front outer CV joint was feeling worn. It makes no clicks, so before
replacing that driveshaft I thought I would ask here and see if anyone
had any other theories. Could it be a strut or strut bearing problem
If I have to replace the struts, I'd like to find something that might
help improve the cornering response. The car seems to want to start to
"push" (understeer, I guess) too soon for my taste. I have manual
steering and it seems to lose effectiveness and get "heavy" right when I
want more turn-in (so I have to slow down or take the turn wider
instead). I'm probably spoiled by having driven a 92 GTI and 03 GTI.
Would new struts help or is that going to be more a function of adding a
sway bar (front or rear?)
I realize these problems aren't really diesel-specific, but I hope the
familiarity with the vehicles will still result in great responses as usual.
