whine normally comes from worn out bearings.
if fresh bearings or the gearset itself make significant noises this is due to incorrect installation. and if this is the case, the solution is not polishing but setting it properly!
i would not expect too much from any surface treatment in a bmw 210 rear axle.
but if you have the budget and are searching for the last tenth of a second in performance, why not!
but for noise reduction only i definitely would not suggest to spend that money. |
In my case, i had some nasty whine from incorrect pinion bearing preload.
If you put your diff back in the car and it is whining, LOUD, it was probably set up improperly. Granted, i have solid everything with no rear, but still i knew something was off. Pulled it back out and got it redone, and it sounded like it was supposed to.
I did not get any treatment, as Florian and i discussed it does not really do much in regards to a part time track car. If it was a full blown race car, in which i was doing enduro and long stints i may have done a polish.
