Thanks for all helpvsnd suggestions. The diff is nice ant tight. Has been recoed. The tail shaft however does need attention. The center bearing is almost split the whole was round and the CV joint to diff does have some play. One thing I have noticed is seems to have a very rough idle at lights recently so maybe a engin monunt has torn...or gearbox mount.......hopefully not a timeing problem.....could I check with forscan?? If its skipped?? Although seems too be idling at 700 rpm....normally 750 rpm
