Noise Coming From Diff In 96 R33 Gtr V-spec

[d_liberate]

Hey guys,

Was hoping you could help.

My mate has a 96 R33 GTR V-spec and he lost it one slippery night and hit the lower drivers side into some pine garden edging.

It caused some damage to his rims, side skirt, some front and rear control arms and the rear cross member/cradle.

Everything has been fixed/replaced now and once he got it back and drove it, he noticed a loud noise coming from the rear.

You can notice it from around 60km/h onwards and it gets louder as you pick up speed. It almost sounds like an small plane is behind us!!

We assume it is the diff so we did an oil change and still no difference. The old oil seemed to be at a good level and a cleanish colour however we did notice a fair bit of steel shards stuck to the magnetic bung.

Can anyone confirm if it is the diff or not? And if so, is the diff centre easy to remove and send somewhere to be repaired? Does anyone know any good repairers? Preferably within NSW?

Thanks in advance.

We're pretty sure its the Diff. Can any one confirm how to replace it? Can we just swap the diff centre with another one from another R33 GTR V-spec? Is it an easy DIY job? Has anyone done this before?

cheers.
