4wd system - 2000 tj
I have a 2000 tj 4.0 sport
I use the 4wd relatively regularly, so I'm doubting this is a problem of underuse.
I was at the Badlands in Attica, IN towards the end of May - this is when the problem first occured.
Problem: 4wd engages pretty well, within 2 or 3 feet of when the lever is pulled - I can hear/feel that I'm positively in 4wd.
When I take it out of 4wd, the light goes out yippee skippy, but I can feel it in 4wd for a long time - dry pavement it stays in the longest. I was on a gravel road (usually when I get on a gravel road I put it in 4wd just so it gets some use - at least twice a month) I took it out of 4wd as I approached a paved road and noticed it hadn't disengaged - I drove and drove wondering why it hadn't when I heard a unsettling clunk, slight front wheel hop and voila! it was disengaged - this was miles down the road. I've repeated this event multiple times, and it seems that a bump will act as a catalyst as well - like something needs the pressure removed to fall out.
Now: I'm not aware of how the 4wd system works in this jeep, I'm used to the more positive lever on the tc systems. Is this the quadratrack system? vacuum activated? why did it take so long? Where do I start? Suggested reading? Links?
*Note If I reverse and pull forward after putting lever down it disengages just fine (which I have to do in older trucks anyway, but the literature all states you shouldn't have to in this jeep) In fact it says you can shift into and out of willy nilly up to 55mph - I never would as I think you're just asking for trouble, but what gives?
Thank you in advance for any insight.
