Ok. I think i will buy 4.7. My diff is still whining after changed my bearings so i guess it comes from my ring and pinion.
Any advice about a good brand not too expensive ? |

The crownwheel and pinion are installed as a set, and create a wear pattern (contact patch) on each other after many years and thousands of kilometres. Once the differential has been dismantled for repair, it can be difficult to get the contact patch exactly matched. That is the usual cause of whining. Same thing applies if you only install a new or used pinion to an existing crownwheel. Worn or loose (lack of preload) pinion bearings can cause whining, and even just a worn out crownwheel and pinion. If the gears appear to be in good condition, you could try adjusting the contact patch, or just put up with the noise, and hope that it settles after a while. Cheers... jondee86 |

I should set up the ring much closer of the pinion ? With the same method showed in the factory service manual ? |

4.3 is ideal for daily, you will have good acceleration and top speed, with highway drivability.
For higher powered AE86 4.1 is even better. With 4.778 anything above 100 km/h will be annoying. |
