Title: Might be normal / Might be an Issue
Post by: jay140285 on December 06, 2010, 01:14:01 PM
Right,

2002 Jeep GC 4.7V8 60th Anniversary edition.

When its cold I have noticed this happening.

Its at low speed, and happened only a few times and after coming off an icy drive or icy road but it feels like a very poor change from the auto box or as it a diff is locking / unlocking and there is a decent clunk noise.

No change in driving, still pulls fine. It feels like when I had a Land Rover and I had to use the lever to put it in 4WD and if the cogs were not 100% lined up it would clunk into FWD.

Any thoughts??

Cheers James

check the correct oil is in the transfer case (or just change it) & check the joints in the front prop, the TC coming in & driving the front axle is seamless on mine. Have you tried in in 4-Lo, that will lock the centre diff take that out of the equation

mmmm, no idea what oil is in the transfer case. what should it be and how often should it be changed??

Its been serviced on the dot but last couple at a independent place not main dealer.

1.6 litres of Mopar 247 transfer case oil

Cost me around £20 when I changed it a few weeks back, wrong oil causes the clutches to grab, may be your issue

No friction modifier in the diffs will also cause bother.
