2002 astro: a locking differential..wheel drive..Chevy

This answer was rated:

i am moving to Alaska and want to put a locking differential in my 2002 astro that is NOT all wheel drive but can't find anything online. there must be something i can do. did this generation astro use the same rear axle as another Chevy product - maybe an S-10? what are my options?
Hello and thanks for using Just Answer,My name is XXXXX XXXXX I would like to help you with your question. I went to the " site" and a search of your van came up with 3 Auburn Limited slip chunks part number depends on ratio, Jegs numbers 542040, 542046, 542041. Also they list a Posi Eaton part # 19599-010 for 3:23 and up ratio's.

I hope this information helps,
