Dana 30 Problem

In the picture below, there is what looks like a splash ring on the binion shaft shaft behind the pinion gear. The splash ring is all chewed up in one area.

The Rig makes a clunk clunk clunk sound when driving and on the gas. I believe this is the culprit.

My questions are:
1) Is this ring needed.
2) Can it be removed without removing the pinion gear


I really don't want to have to reset up preload on this dif, but will if I have to.

Thanks in advance...

Gary

To answer your questions:

1. You'll have to inspect all the teeth on the ring and pinion to make sure they aren't missing a tooth or have been damaged. If you have to get another ring you have to buy them in a set since they are machined to fit each other. If that happens then you will need to set up the backlash and preload. But using the existing shims gives you a good starting point.

2.Yes the ring and carrier can be removed without removing the pinion gear. I would take a picture of the assembly and make sure to keep all the parts in order like they came off the diff. You don't want to install the caps upside down or on the wrong side.

If you're planning on replacing the oil slinger, then yes you will need to remove the pinion because its sandwiched between the pinion head and the inner pinion bearing. Have you turned the pinion yoke by hand to see how it feels and where the problem might be?

Actually I have one more:

Is the oil slinger needed or can I safely eliminate it?

You need it. It helps lubricate the pinion bearings. I saw where yours was bent. Do you know what caused it?
