Need Help - Rear/center Diff (r200 Short Nose)

[GTS4-32]

Hey guys, just recently bought a R32 GTS4 and am having problems with the rear diff. Its a whining noise that seems to get louder the more the speed increases. Chasers Motorworks have had a look with the previous owner and it came down to the center diff; R200 Short Nose. (same as gtr, also found in other cars).

To be more specific, what he told me was that i need to retain the crown wheel + uni joint, in order to maintain the right ratio.

I have been quoted $300 for the part that needs to be replaced. If anybody has a spare R200 Short Nose laying around, let me know asap with a price and we can take it from there.

Thanks,

Steve.

hi this is brad from chasers motorworks... just to clear things up, i beleive we would have told you or the previous owner that the noise was either wear on the crown/pinion, or most likely the side or pinion bearings. so that means you dont need to replace the diff centre or housing. you need to have the diff inspected and advised exactly what needs to be replaced.

My diff made the same noise, i took it to a diff lapping shop, just the centre since its cheaper then getting them to take it out, and turns out the pinion was nearly ceased and the carrier bearings werent exactly the greatest. Cost me about 500 for it to be rebuilt, inclu new seals and bearings, havent heard a noise since.

Its better than going out and buying used parts, atleast you know the jobs been done properly

Thanks brad, yea well the previous owner told me all this, you may have dealt with him yourself, his name's Vinny with the gun-metal grey gts-4 with gtr kit....apparently you know him and his car well.

He told me exactly what i wrote earlier on according to you blokes.

But yea, its a good idea to get it inspected once again, for myself and have the right parts replaced correctly. The info you just gave me though clears it up better for my understanding of the situation, so thanks again.
