Holy crap. Ctu i appreciate it but you didnt have to type all of that. Must have been like work.


Can anyone tell me about the axle..... Like in 4x4 is this like my explorer and open diff or limited slip

 

Yeah, it takes a fair while to look up all that stuff but ya get used to it, I guess.

It's an open (non-locking) axle.
