How do differentials work?

Post by A112H »

This is the best video explaining how a diff works I have even seen. Love it from about 3:30 in.

ISKA8 I hate rebuilding diffs... it takes experience of repetitively doing them to get the knack... or youll get a whine or huge backlash,then have to take it out adjust(shim)more or less..
but thats just me...only done two rebuilds myself :P

nice video :thumpsup:

as far as i kno harry you have to press the pinion in then the yolk and a new pinion bearing when done its prick of a job my mate wit the r31's said as he attempted one, also i've pulled a far few diff's apart selling gears and centres for a lil profit recently on ct, there even a prick to pull apart :@ but easy done now wit a pully remover n some home made tools :P

i only paid $400 irs centre droped off picked up for the sv gears put in with a spool and new bearings all round seemed to be a good price i thought (thomstown trans and diff n gears) even just get a qoute for the pinion to be put in and u do the rest i can even help at this stage :thumpsup:

also with welding the diff if you kno a good welder there's plenty of info and pic's on how to do it on the net (calaisturbo, skyline's aus, r31club) cant remember which forum its on...
