j30 vlsd problem - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

I just installed my newly purchased 94 j30 diff with 5 bolt axles and about 10 miles after I installed it, It started to whine. It only does this when accelerating and when I am at a constant speed at any mph. It got so loud that I literally couldn't hear myself think. I was just wondering if I am going to have to replace the carrier bearing or if it is something else that I need to replace. I used the stock non-abs driveshaft and I have heard that could be a problem but only if you leave it like that for a while.

Oh, and the oil was a little low and it was installed on a s14. It has all new wheel bearing, ES subframe bushing, toe rods, rucas and stance Gr coilovers.

Any advice and help is much appreciated.
