The key is to gradually tighten the diff to break it in properly and obtain the correcttightness. DO NOT overtighten the diff initially or damage will result.When initially tightening the diff, the screw should be tightened enough so that diff cannot be rotatedwhile holding bothWhen breaking in the diff, the balls create a groove in the diff rings; this is normal and essential for properoperation. If you overtighten the diff initially, the balls will mar the surface of the rings (and damage the parts)instead of creating a proper groove in the rings.Adjusting the differentials is easy to do. Tighten the diff until you feel some resistance; you do not need to make large adjustments - 1/16 or 1/8 of aturn will make a noticeable change in diff tightness.Reassemble the car, run it for a few minutes, and then tighten each diff a little bit. Repeat this several times to break in the diff and set the correcttightness.930020B 2.4930407BB 4x7x2.59072702.5x20960025N M2.5930025BA 2.5x0.8930812BB 8x12x3.5
