Hi,
As explained above garage did change the bearings etc, but the real difference was made when I changed the rear diff oils.
Bearing in mind when I drained it only 1 litre drained out, and it didnt smell much like LSD oil it explains alot!!!
Replaced it with proper LSD oil (3 litres) ran the car for 1000 miles, then replaced again.
100% improvement in reversing, turning corners and felt better just in general.
If you've got the same problem I'd start there - simple job to do yourself, and shouldnt break the bank! :thumbs
