Re: NO 4 wheel drive
Is your jeep Quadra trac II or Quadra Drive? Then it has the NV247 T-case which has a progressive coupler for the 4 all time function. Many times this coupler is not working anymore. You could try a fluid change, but most of the time the coupler is shot. Very expensive part, so you better look for a junkyard 247, or swap to the 242, which gives you the option to select 4 hi.
