I am in the process of rebuilding the rear diff on my 1977 RB.
It has developed the dreaded "clunk" when accelerating.
The fix for this is the replacement of the 2 brass spacers. Unfortunately they are no longer available in brass and replaced with kind of fiber ones. Does anyone know why they did this and what about the long time durability of these new spacers ?.
Werner, Glenn Towery on the MGexperience board has stainless thrust washers.
Stainless has a bad friction coefficient so why use it ? The originals were made of bronze
Werner, The original are composite and the stainless is softer than the hardened steel gears. Most differentials use mild steel thrust washers and I like Toyota's design with oiling holes. Can't argue with Glenn's 600,000 miles on his!
