what diff is it?
mines away getting done at the min aswell lad, it was my bearing that went, they hav to be pressed out aswell so it might be a tricky job bt then again i know nowt lol and sorry i dont hav the name of the lad thats doing it hes down in tullamore
cusco 2 way ste
the cog im after is the 1 that spins wit he main diff teeth if yas get me?
its hard to explain coz im not sure of the name.. but when ya have the casing open and you can see the main part off the diff its down behind that near were the prop joins the casing and the teeth off it slot in wit the main part of the diffs teeth...
its the gear that the prop shaft turns to turn the diff itself ya mean??
pinion is the word your looking for

so i need the pinnion so..?? does any1 no wer id get 1
genuine nissan id imagine, and you might aswell get the bearings too (if the done come with the pinion), as i said they need to be pressed out and diff casing stripped to get access to them, so you will need to reset the back lash on your diff when its re-fitted

if you hav he car on a lift you will be able to move the prop shaft a certain amount before the back wheels will start to move, that bit of play is the backlash, and if thats not reset the way it should be it could make a mince of your diff, just incase you where gonna try the job yourself just give yeah the heads up :)

crownwheel and pinion are a matched pair, you cant change one without the other.
is the crown wheel not on the actual diff itself? and the pinnion in the casing??Quote:

Look under your car, you see a big metal thing with the propshaft going into it and 2 driveshafts coming out of it, thats your rear diff casing. Its where you pour your diff oil in/out
The propshaft turns a gear housed inside the casing, thats called the pinion
The pinion turns a much bigger gear, thats called the crownwheel.
The crownwheel is bolted on a round metal thing, thats called a diff.
The number of teeth on the crownwheel and pinion is what defines your final drive ratio (diff ratio)
If there is 13 teeth on the pinion, and 48 teeth on the crownwheel, your ratio is 3.69:1. (48 divided by 13) so, if you rotate your propshaft 3.69 times, your wheels will turn once.
The gears are a matching pair, if you mismatch them, you will end up not driving very far, and making alot of iron filings!
Comprende :)
perfectly:cool:
thanks man thats basically everyting ya could ever need to no about a diff.. cheers:D:D
