Hey guys, so those of you who attended Kadina Show'n'Shine would remember what happened to Krishy's car. If you weren't there or were too drunk to remember, he took off, changed gears, and then the car just free revved in gear. Upon further inspection, you could see the tailshaft was spinning into the diff, but no drive coming out.
The diff, a Tomei 2 way 4.11, had been in the car for roughly 3 weeks, after being swapped into the place of the factory A-LSD unit found on some R33 GTS-t's.
With the car jacked up, the LH rear wheel would free spin by hand, and the RH rear wheel had a bit more resistance on it, and would also turn the tailshaft.
We drained out the oil, and saw nothing too major apart from some metal filings. Once out, the first thing we did was remove the cover, and much to our amazement, everything looked quite good and clean. Both of us were expecting to see major mechanical carnage.
We pulled the half shafts out the diff, to find the teeth from the LH side were shaven clean off, but only on the very end, almost like the shaft didnt go in far enough. When we pulled out the other side, it became evident that the 2 shafts were different. Both had 29 splines, and both were the same overall length, but the length of the 'middle portion' is different. I'm assuming this is not meant to be? It looks like the shaft from the LHS wasn't going far enough into the diff centre, and has simply sheared off. The diff centre appears to be fine and in working order, apart from the metal filings from the shaft.
LHS:
RHS:
Can anyone shed some light on this? It would be much appreciated
PS. If anyone knows how we can clear the metal filings out of the diff, that would be a great help too
