I spoke to Geartorque yesterday - his quote over the phone to rebuild my ZF LSD with new bearings etc was a rather astonishing £680+vat. I explained I wanted a check over & refresh, new bearing etc, and he suggesting Id be wasting my money if its not excessively noisy. I also spoke to Alan Voights in Wallasey, Merseyside and they quoted £355+vat for the same with a week turnaround. That would be a clean, check, bearings and reassemble like for like, keeping the internals and CWP the same.
