Re: 740 Estate - Rear Axle Bushes
It dawned on me yesterday that the symptoms of this problem only began after
I bought a new tyre (following a puncture). When I measured the diameter of
the new tyre and compared it to the tyre on the other side, the new one was
6mm bigger (just from normal tread wear). Summising that if the car is
fitted with a limited slip differential, under power the offside wheel would
travel around 20mm further than the nearside, and under deceleration, the
diferential would free up and remove the one sided drive effect.
So I swapped the front wheels for the back ones (fronts fitted as a pair and
of equal diameter) and, hey presto, the problem has gone away. I would
never have believed that such a small difference in tyre diameter would
cause such a significant effect on the steering. Also, it turns out that I
have a limited slip differential, which is nice!
No need to change the bushes after all!
