Trouble with my 4wd

I have looked everywhere for help. I used my 4L in my 96 Grand Cherokee to get out of a snow bank. After that I put it back in full time. I began hearing a winding noise that changes with speed and I noticed that the front tires are hopping while turning. I've never had these problems before. I haven't used my Jeep since, but there is a big snow storm coming this week-end and I need my Jeep. Can someone help me?

Re: Trouble with my 4wd

Time to climb underneath and look. The 'winding' noise worries me less than the wheel hopping...that part is not normal. Look at your front driveshaft...make sure the cv joint did not pull apart.....they have a tendancy to do that if you have a lift and your front suspension gets fully extended.

Considering what 'little' information is in your profile, we have to assume that your GC is stock....hense, it's unlikly it's your cv joint on the front drive shaft.

Unless you have a floor jack, you might as well plan on taking it to a mechanic so he can put it up on a rack with the engine running...that may be the only way you can find the problem....

The only thing I can suggest is to maybe put it back down in to 4L and then back up to Full time to make sure that you are out of 4L.

One last thing....I would suggest that you post this question over on the Jeep Mid-Size board...this board is for the shorter jeeps, like CJ and wranglers. The Mid-size board is all Cherokee's and GC's....much more experience over there.....

Re: Trouble with my 4wd

Sounds to me like it did not come out of 4 low, Like John said shift her back and forth a few times, put it in 2 wd back up and pull forward a few times. Heck my tj with the passive cable system does not actualy come out of 4wd until about 25 mph and with a front locker that can be fun when it pops out.

I often have to back up to "POP" it outa 4wd.. Good luck

Re: Trouble with my 4wd

The front wheels are hopping because it's still in a locked mode, where both driveshafts are being forced to turn at the same speed. Try backing up in a straight line for a few yards. That might be enough to get it to come out of locked mode. If that doesn't work, try jacking up the front end. With the tires off the pavement, all of the stress on the drive train will be relieved, and it should come right out.
