General Maintenance & Repairs - No gear. oil

So I, like many others, have a bad rear pinion seal often. The last time it was taken in my dad brought it in for me. It appears that it was not fixed, since I got a terrible whining sound out of the rear about 100 miles away from the destination of a long trip, and it kept getting worse.

The rear end makes a loud whining, screeching sound now at ANY speed. It's currently at Pep Boys (I'd do it myself if I were home), the only place open on Sunday here, getting new gear oil/LSD additive put in it, since it now sounds like there is NONE in it.

I was wondering if the rear is going to be significantly worse off from having run 100+ miles on low/no gear oil. Seems to me the answer is yes...

I find it hard to beleive you lost a lot of fluid from a pinion seal. My 2000 SS went for years with a leaking seal, and when I changed rear ends it was still almost full. My car had 60K on it and the rear was mint. Lots of track time too. :) I don't think you should have a problem.

oh yeah, and nice car. :)

Well it's screwed. Added the oil back in and it still screeches like a mother.

There was no oil in the diff at all, and there were a bunch of metal shavings that came out. And the idiots lifted the car directly on the "do not lift here" tabs. Assholes. Well, perhaps I will get a Moser now... anyone care to guess what damage has been done?

Was your rear cover seal leaking too?

It did not look like it was. It had been leaking from the pinion seal for quite some time, however.

I bet they impacted your pinion nut back on and now your pinion bearing needs to be replaced.
