lsd passport/rodeo

did passports and rodeo come with limitted slip differentials with the full time 4wd option? i'm looking for stock lsd parts i can swap into my trooper for better traction and a cheaper fix. any help would be appreciated.

yup they have a lsd option, but they have a dana44 and I think you have an Isuzu corp 10 bolt or something like that.

What vehicle and what year? And how do I know what to look for?

I dunno of any rodeo/passport with "full time" 4x4, but if the unit came with a factory rear LSD, you will have a "G80" code on the firewall VIN/option code tag.
