I have an 07' RRS SC and need to replace both diffs after getting it stuck in a swamp for an hour (rear has a clanking sound and wheel judders when turning at high angles), front diff is leaking. My mechanics opinion is they both should be replaced with remanufactured originals. I would love to turn this lemon of a situation into lemonade. I've been considering getting an ARB locking diff for the front for a while anyhow... is it possible to fit a rear elocker diff (one of the ones that would've been an HD add on)? It seems like the major snafu might be not having the right wiring on my harness already. I've tried looking at the related threads here but didn't find anything specifically confirming or denying.
