NO 4 wheel drive
My 1999 Grand Cherokee Laredo has 4 wheel drive all the time, but only works in 4LO. Any suggestions to get the front wheels working? :confused:

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.

Thanks! I'm gonna try changing the fluid, if that don't work then the search begins for a new transfer case

The NV247 T case needs special Mopar fluid, which is Mobil 424.
