My wife traded in her S40 for a 2001 V70, 2.4 model with 74,000 miles, a
few weeks ago. After driving it for a while i've found that it seems to
have an unbalanced feel to the engine/transmission - difficult to
describe - that makes it rather tiring to drive. It has this vibrating
feel at most speeds, although the steering wheel is pretty steady.

The dealer is going to balance the wheels (it's running on Pirelli
p6000s) and check the steering geometry - but I was wondering if there
is something else we should be checking.

Thanks

Marc
