Had anyone rebuilded a awd diff ?? Just asking if is better to rebuild it or just buy a used one since there is different diff with gears ratios. Does the nismo rs diff will fit my 2011 ??
^^^^^^^ This ^^^^^^^You asked, so I mentioned it. The clutch packs can be rebuilt.....yes. The service manual shows how to do it and the exploded parts list. This would be about the only inexpensive part of the rebuild. The electromagnets are insanely expensive but without diagnosing the problem it's impossible to say what your particular issue is. Are you having problems with the torque vectoring? Can you fully lockup the rear differential to AWD-mode to confirm? Is the rear differential overheating? There is a diagnostic fault tree in the Service manual to check the differential, I'd start there before just tearing the unit apart.
