I'm sure this has already been done, but I'm not sure how to phrase the search, and I needed to use up my "dumb question quota" anyhow (how many are we allowed per year? I've got four or five years' worth stored up...)
Anyhow, I just had my 88 up on a lift last week (1988 2dr Laredo/4.0/BA10/NP231/D30/D35) at school, and I've been beating my brains out on this...
The front tyres, spun by hand - spin one forward, they both go forward. Spin one backward, both go backward. Didn't hold one and spin the other - forgot to and class ran out.
The rear tyres - spin one forward, other goes backward. Hold one, other doesn't spin.
I haven't added anything to either axle but oil, and I don't remember seeing anything unusual at prior services. I'd have to crawl under to read the tag (I know the rear one's still there,) and according to the previous owner, nothing had been changed.
What are the odds I've got some sort of LSD in the rear, or do I need to post more information? I've been thinking on and off for the best part of a week, but I've had my head wrapped around engines long enough that I've forgotten basic axle tech, and I'm not sure where to look...
I can post Dana BoM numbers (as available) in the next couple days, if requested. I'd have to find the list I did in Excel before I could use it - unless the Dana Expert site is still public... Just thought I'd try here first.
