LSD whinning

[Rasteirinho]

Quote:My question is. After a ring and pinion start to whine is it possible to reinstall correctly producing less noise? Or do I have to get new parts to solve my problem?

I don't think you ring and pinion can be reused again without noise.
The noise is produced by a incorrect contact between the tooth of the pinion and the ring, if you ran many km with an improper contact you will change the helicoidal shape of the tooth and you'll never be able to eliminate the noise.

As you know, the same thing happened with me and the only solution i found was to order a new R&P from Spence.
Until yesterday no problems with noise but after the yesterday's trackday, there's already a slight whinning noise around 3.000 rpm.

The problem with shorter FGR is that it becomes more difficulto to properly tune the contact between pinion and ring. The less number of toothe you have, more difficult becomes the tune.

In my case, if the noise appears again i will go back to OE FGR.
