    Pinion bearing

    Hey all. Does anyone know a good place that I cam get my pinion bearing changed in the front diff ??

    It has play and is giving me serious vibrations. I can maybe do myself but am worried about shims and such. Haven't completely torn front diff apart before.

    Thanks

    O it's a Dana 30 with 4.56 gearing

    Check to make sure it is not simpley the pinion nut backing off. Frequently, this is the issue....especially if someone has been in there changing pinion seal or doing a gear swap. There is a crush collar that is a one time use item that sets the preload. Often, there is an attempt to reuse it which will result in inadequate pinion bearing preload and the nut slowly backing off. The castelated locking pinion nut is also intended to be a one time use item as well.

    A quick way to verify if this is the problem is to unbolt the driveshaft at the pinion and try to tighten up the nut. If by tightening the nut you remove some or all of the slop, it is most probable that you only need to replace the collar and be on your way.

    You will need a new pinion nut, crush collar and pinion seal to do the job properly. It is not hard to do and you can do it yourself.

    I'll check that for sure. Thanks a lot
