Hi i was just wondering what could be wrong with my 99 jeep cherokee sport everytime the 4 wheel drive is engaged and i turn the wheels to the left or right at a certain degree the front tires start to lock up a bit....any answers would be appreciated and would give me an idea where to start, Thanx

If it's the np231 transfer case as in "2H,4H,N,4L" then you are using it on terrain where the wheels can't slip and its binding your drive line. Don't use your TC on dry pavement. You can damage a lot o of things that way.

Nothing is wrong. The reason it does that is because both driveshafts are turning at the exact same rate but all 4 wheels are turning at different speeds. If you are not on a slick surface (dirt, snow) then you will bind everything up and your jeep will not be happy.

Read your owners manual on how to operate your transfer case.

i never use the 4 wheel drive unless needed i try to get around things in 2 wheel drive...i was in snow both times it happened thats when i figured something was wrong so i figured someone might be able to lead me in the right direction on where to look...didnt think it was my wheel bearings or my u joints i didnt think it had anything to do with the cv joints but thats y i asked so if anyone knows of what it might be it would be very helpful...thanx again

If it's starting to do that when engaged it just means it's not slippery enough to use it.

even if my back tires are spinning and im not moving anywhere?

I don't agree with this. It will do it on dirt in 4lo at full cut. It's just the drivetrain fighting the terrain.

i know my step dad also has a cherokee with the same transfer case lifted 4.5 and 5 in the rear his is stuck in 4 wheel and ive not once heard or seen his fight it when turning on dry pavement like that ever

If his is stuck in 4wd and doesn't do that on dry pavement then idk what to say. That to me sounds like it's not in 4wd. You should not be able to turn at full cut in 4wd on dry pavement without binding/hopping

Check your axle u-joint they bind when they are going bad.

Absolutely true.

OP needs to do some noggin pokin.

i didnt know they werent meant to be fully turned in 4wheel without the kick and go that was my problem....but ya his is stuck in 4 wheel and cant get it out he needs a new transfer case but ya never heard his pop thats y i got concerned a bit

Okay. You're new.

Have you ever checked the fluid levels/condition in both front and rear diffs, transfer case, and transmission since you've owned this Jeep?

What's the coolant look like?

Have you greased every zerk fitting on the driveshafts and front suspension and at the same time visually inspected components for wear?

How about those u-joints at the outer ends of the front axle?

What kind of shape are the brake pads and shoes in?

Motor mounts and trans mount in good shape?
