Hi all - New Brisbane member . Didn't even know this forum existed until I was searching for info on my noisy diff and discovered you all. Have a 1984 Sprinter all totally stock but getting quite old now, paint fading, engine tired - had her since 1994 and she has 421000 on the clock - bought her with low 100ks and I suspect the engine is still original - oil gets changed every 4000 k's so that has aided the lifespan. Wife always tells me to get a new car if I want but I just love driving the Sprinter too much. Good luck to you all and I will endeavour to get some info on my diff eventually.
