Our 85 seems to have some kind of posi or LS. I have done some research and it doesn't seem that they ever came wit any kind of traction package. Is there a possibility that it was a special order option?

what's the axle code on it?

snippets:

Final Position - number of pinions in the carrier

3 = 2 Pinions (LSD)
(I've not ever seen this code in a pickup/4Runner)

5 = 4 Pinions (LSD)
(I've not ever seen this code in a pickup/4Runner)

I'm not sure. I will hafta crawl under there and get back to ya.

should be listed on the vin plate.

The plate says G292. So apparetnly not Posi or LS from the factory.

thx LSUfan71, always forget about toysport, their graph is actually easier to read and pringt out for that matter.

Thanks for the info guys. What would have had the 3 or 5 last digit? Would it be a bolt in carrier?
