Its getting worse. Do I even have a differential that was originally installed?
Upon perusing the GoMog Salisbury Diff images, I see a few serious differences.
1) No top filling hole. (I only have bottom drain and a fill hole halfway up the rear right side)
2) Casting number is 7NA-004-15 (hard to be sure with some numbers, but is definitely 7NA.
If I can figure out how to post photos, I will do so, just so someone here can confirm that I am now dealing with a mutant diff.
Was on the phone to a diff. guru in Brisbane who seems to think that I should change the wheel bearings first to exclude them as a culprit.
I'll order a complete set of bearings and seals and get to it in the next 2 weeks or so.
Will advise the outcome of the bearing/seals change in a couple of weeks.. or however long it takes for me to receive them.
