The differential was noisey on my sierra so time to get it sorted, once removed I drove it over to Bara Motorsport in Bromsgrove near Birmingham, it's a 250 mile round trip but they come highly recommended, I had arranged to drop it off at 9am and should be done by 2pm which it was.
Cant recommend these guys enough, Diff was stripped cleaned and reconditioned with new seals and bearings and properly set up.
