I'm going through my spare diffs. The one on my parts has many broken teeth on the crown. I'm wondering how that could have happened: Maybe a ball fell out of a bearing and caused havoc. The PO had drained the diff. Fortunately, I was able to remove the side flanges with a 12 ton press. Out of 6 flanges I was able separate 4.
With the diff I have on my bench, I'm plan to swap the pinion housing with one I strengthened. I bit the bullet and bought an SKF bearing. However, if the existing bearing is a good brand and is healthily, I will consider reusing it.
I'm in two minds whether to add a drain plug. The original size fill plug seems too big to add. An alternative is to maybe drill and tap a small hole and use a copper washer on the end of a bolt to seal. But the bottom does seem flat. Any recommendation welcome.
Also the last time I changed the seal on the side flanges, the diff leaked between mounting plate and diff. When reinstalling should smear the face with Hymolar or something similar? I'm planning to replace the rear cover gasket. While it is off, is there tail-tail signs I should look for? So far there doesn't seem to be too much play in the diff, With the diff cover off, should I see some visible wear patterns where the pinion is meshed with the crown?
The Diff is marked with the following LD6978. Can anyone tell me the approx. year of this diff?
I posted a posted a separate question about the main pinion diff seal as it wasn't answered in another post.
Thanks in advance. Sujit
