hey i was on ebay and saw these gears for sale, its a limited slip 3.73's for a 7.5 rear which i have and would like to do 3.73's but it says in the auction that they came out of a high mileage vehicle and was wondering if you guys think these gears are in good shape and how long do you all think they would last?
here's the link: http://cgi.ebay.com/ebaymotors/aw-cgi/ebayISAPI.dll?ViewItem&item=601410143&r=0&t=0

Thanks

Welllll, the seller's rating is 214 positive, zero negatives, so that's a good sign.
I would go into it mentally prepared to rebuild the clutch pack in the diffy (and maybe bearings).
I see he's throwing in the ABS ring.
You can ask for the mileage, but I don't know where the distinction of "worn out" begins.
Hhhhmmm, can't think of anything else. Good luck.
