4 Wheel drive question

Last night I shifted into four wheel drive and it was whining a little bit and then when I got where I was going my Jeep kinda jolted a little and then it was driving like I had a flat tire. Once I shifted out of 4 wheel drive it was fine. Any ideas????

Sounds like you were driving on a hard surfaced road and either your tires are not all the same size or your tire pressures are not equal.

I would check the tire pressure like Red Rubicon suggested. When I use 4wd, my TJ whines for about 30 seconds and then stops. You might want to change the front diff gear oil, not sure if that would make a difference but I recently changed mine and overall 4wd is MUCH less clunky. Thinner oil in the winter is suggested if your in the north but I use a 80w gear oil in Michigan because I am around 200,000 miles. Just a suggestion.

It is a 2005 wrangler sport straight 6 with a stock transmission. I have brand new tires on it. Has nothing to do with the tires just felt like the 4 wheel drive was wobbly or something. Have switched it in to 4 wheel drive since then and it doesnt act like anything is wrong with it. May have just been a gremlin.

When was the last time you used 4wd since the problem started? When I bought my 98 its 4wd hadn't been used it at least 6 years. I replaced the front diff oil. Took me at least a half hour to get the handle to move into 4wd, after that it was clunky for about 5 miles and then smoothed out. Beats me, glad its working for you.
