Hi all, I'm thinking ahead to a possible job for next year - fix my whining diff. To those of you who have already done this fix, I'm curious as to how I should approach this. Do I a) remove diff and refurbish it or b) replace it with something else? If it's a) refurbishment, what parts do I need to cary this out? Any help / tips gratefully received. Regards, Graeme PS. Car is '73 US import. Not entirely sure which type of diff it is I have.
