From HMS...
FYI...As a Quaife America dealer we send diffs to Quaife for inspection re: wear,debris,damage etc. In most cases the only charge to us is shipping. Do not DIY the internal inspection of a Quaife, you will void the warranty. On Torsens we, HMS, have stripped and checked many units as it appears Ford Racing/Torsen do not offer this as a warranty/check service. An ATB diff is a complex piece of engineering, should not be considered a DIY job unless you have done them before. TH
