turning radius problem

So sometime last week I was driving and went to make a sharp turn and my jeep started to jerk and it felt like it was stalling. I checked and my left sway bar end link was broken. I replaced the end links with quick disconnects today and went driving and the problem happened again. I checked the wheels turned all the way left and right and I couldn't find anything that is rubbing. Also when you turn the wheel as soon as it gets to the full turn it starts to make a whining noise. If i let off a little on the wheel the noise goes away, but as soon as i turn it back to the full turn radius the sound comes back. I have no idea what could be causing this. Any input would be helpful until i can have it checked out at the shop. My jeep is a 97 TJ 4.0 with a 2.5 skyjacker lift, other than the sway bar end links everything upfront is still stock.

Whining like the steering pump, whining like metal scraping/grinding, or whining like a belt?

Have you checked your axle ujoints? Unit bearings? Are you sure your tire isn't rubbing the control arm?

UFO is right, sounds like power steering pump, I'd check all moving parts on front end looking for shiny metal ( signs of rubbing ). Check bushings on all control arms for rot and steering shaft and sway bar. If its that bad u should find something bad

The whining is normal when you turn your wheels until they hit the stops (or what ever is actually stopping them from turning further). Don't hold pressure on your steering wheel when that happens as I'm sure it's not great on the power steering pump. If your tires are wider that stock, you are almost certainly rubbing against the lower control arm on the driver's side when turning left and/or the passenger side when turning right. If it has been rubbing a lot, you can probably see a shiny or black spot on the control arm where the tire has been making contact. Generally it's worse when you are turning while backing up than moving forward but it can rub moving in either direction.
Normally you have to adjust the steering stops by backing out the bolt, and adding several washers behind the welded-on nut. This will slightly reduce your turning radius, but will stop that annoying rubbing that you feel and hear.

The steering stop is circled in the picture below. There is one on each side of the axle. The driver's side stop controls rubbing when turning right and the passenger side one controls rubbing when turning left. It only takes a couple of minutes to fix. Back out the bolt, add a couple of washers under each side and try it out. If it still rubs, add another washer until the rubbing stops.

This may not be your problem as I haven't seen this kind of rubbing on stock width tires as long as the front axle is still centered in the vehicle (which it may not be given the lift that you have). If you are rubbing on the control arm, it often only happens under load and you won't see it with the vehicle sitting stationary.

If your axle still has the stock track bar, it may not be centered, because as the vehicle body and frame where lifted, the axle moves in an arc away from the frame based on the track bar geometry. As the axle moves further away from the vehicle frame (suspension is lifted), it also moves toward the driver's side. This moves the passenger side tire closer to the control arm on that side and can cause rubbing when turning the steering wheel to the right. Many small lifts do not address this issue and if this turns out to be what's going on you have a few choices to remedy it:
1. Add washers behind the driver's side steering stop.
2. Add an adjustable front track bar
3. Re drill a new mounting location for the front track bar where it attached to the axle end.

So with the tires pointing straight, does it look like the front axle sticks out slightly to the driver's side (and the rear axle sticks out slightly more to the passenger side)?

As UFOtestpilot also mentioned, if it is not a rubbing issue it could be related to worn out or broken front u-joint on the axle.

Were you turning with 4wd engaged on the pavement?

If you ran with it engaged on pavement you could have done some serious damage to drive train parts. Are you sure its out of 4wd? Jack up front axle and make sure both tires spin freely.

If the roads were snowy you are fine. You just don't want to be driving on high traction surfaces like dry pavement in 4wd

Okeydokey, so say even though i disengaged 4wd but its still stuck in it what kind of problems could that cause? I know I had a minivan before this that was 4wd all the time so its new to me that 4wd could actually cause damage

Some vehicles have full time 4wd that isn't damaged by use on dry pavement. But Jeeps use a locking 4wd that will cause binding if there isn't sufficient slip when you turn (both wheels want to go the same speed). That can damage the drive train and steering components.

I learn new things everyday! And it was indeed still in 4wd because i havent driven my jeep since it was snowing and i forgot to disengage it this morning. Disengaged it as soon as i got in (and felt pretty dumb for not noticing it when i went out this morning) and I started doing sharp turns and it was just fine.

Keep an eye on your axle ujoints, they may have taken a bit if a beating.

So that's why the tech support guys ask if it's plugged in as their 1st question ;-). Glad to hear it was just that you had your 4wd engaged.

Mine does the same thing when backing into parking spot. I've learned to let off the wheel a little. Showed it to my mechanic, he said it was fine as long as it doesn't show wear. And when it does, to bring it back in to him.
