Having trouble with my 700. Hoping this site will help figure out what the problem is. Had a bad vib/noise coming from the front differential. I have disassembled the front end and pull the differential. I don’t see any problem with the gear that drives the limited slip assembly. I see how the diff. Lock works but don’t know if the gear that drives limited slip assembly should disengage. When I had the front jacked up the right tire was very hard to turn. WhatI need to know is how the 4wd engages. Any help would be appreciated.
