Diff Problems

[Parf]

Hi

Im having a problem with my altezza. Whenever I pull off and change gear in first and second when I let the clutch out i get a clunk. I noticed that when i turnt the driveshaft by hand theres a little play before it engages the drive shafts. Theres also a roaring noise if i let off going down hills.

Going by what Markrs200 says with the have you got a diff post as below

Look for the codes

ao1a-no diff

ao1b-have a diff

ao2a-no diff

ao2b-have a diff

so if this code ends in B it means u have a diff

Mine ends in a b so I should have one but when I jack both wheels and spin one the other doesnt turn.

Have I got a problem with my LSD or havent i got one.

Cheers

Yes its in gear when this happens, but it wasnt in gear when I jacked it up and spun the wheel.

well the movement from the wheel is going to the gear box and spinning that !

try it with it in gear then the other wheel will turn !

Maybe try and change the oil. The torsen relies on the oil to make it lock up so maybe your oil is gone bad

How do you drain and refil the diff oil?

What oil is best?

[Parf]

Ive changed the diff oil and the gearbox oil but still the same. the oil that came out was clean too.

easiest way to know if your car has LSD is to do a rapid take off with the TRC button off...

If it lays down TWO burn marks (no. 11's) then you have a LSD ;)

@Enda ... sorry but i think the oil in a torsen diff is only for lubrication..

thats what i thought too !

try the test but with one wheel on a slippery surface (dirt grass ect)

and pull away quickly

both wheels should spin and not just the one with out grip !

i was well impresed with how easy my diff locked up on friday !

i pulled over along a single track road to let oncoming trafic pass

one wheel on hard pack dirt and the other still on the black stuff.

just pulled away promptly and got tire squeel from the one on the tarmac !
