The Spartan locker is great but I would not recommend for DD its a bit rough. The locker I liked for DD is the Aussie locker, it rode smooth, luckily this is not my DD.
Thanks for the compliment DW, the tranny/transfer were refurbished. The vibration I cant seem to pin point.
Sounds like you need to do a bit more suspension tuning... A little but of camber and toe as well as some "stiffer" shocks usually fixes that.... And moving up in t-bar thickness can help as well... Ifs lift kits are a 1 size fits all but they still need to be tuned for your driving style
Nope. Everything that could be changed, has been changed so Idk. Next on the list is dumping that crappy 3.0, added everything up to do headers, exhaust, tunning etc. and its more cost effective to just replace it. Thinking 350 since there's a lot of info out there for it.
