Steve, CV joints are most frequent cause of this sort of problems. It is
good idea to have them disassembled and inspected, as simple check for
free play may not reveal some problems. Apart from that, cleaning and
regreasing joints will sure prolong their live. I've had this job done
and mechanic also swapped them left to right when installing to make
them wear evenly (interesting trick, I've never heard about it before).
Also pay close attention to suspension and subframe bushes. Combination
of worn bushes and unbalanced tyres can give _horrible_ effects, BTDT.
