Wobbling when applying brakes when going ~100KM/hr

For a little while now, when I'm on the freeway going around 100 KM/hr and apply my brakes softly, my steering wheel wobbles left and right about 1-2" either way.

The jeep of course wobbles as well and it scares my wife quite a bit since the 2 kids are in the back.

What is causing this? A warped rotor? Should I replace this ASAP? I had my rotors and calipers replaced over 5 years ago.

The 2000 WJ has 158k.

If I had to bet is sounds like a warped rotor to me. If you need them we now ship internationally. Here's a link to them on our website for your Jeep.

So many to choose from! How do I know which to get? I wouldn't mine getting the better type of calipers (teves vs akebono).

I am experiencing the same thing. 2000 WJ 110,000 Miles. Also got a lil bit of a squeaking noise when I hit a bump or pot home. Worse in the morning.

I found the easiest fix was to remove the wife and kids.

I would as well, check your track bar and front control arms for bad bushings. Going over 80km when I brake harder, feels like my rotors are warped, but they aren't. My lower control arms still need replacing. (tops done, lowers waiting to get in, which causes it) Any time I've had warped rotors I usually feel it easily anywhere above 60km.

That sounds like a Chrysler solution to our gas tank concerns!

I bet one of your front calipers is sticking. Upgrade to akebono and replace your brakes. Worked like a charm for me. Had the exact same issue between 50-40mph.

Warped rotor. I got stoptech rotors and love them.

I had the same exact problem and TJSWJ was nice enough to help me out yesterday.

My caliper was sticking, and it almost certainly seemed like the reason was brake related, but upon removing my front axle - the bushing on my axle was shot.

If I take a front wheel off, how can I check to see if the rotor is actually warped? Is there a tool I need or will it be obvious?

Also, I went on a road trip over the long weekend and the steering wheel shook so violently that the wheels wobbled back and forth (with clunking) and I felt like I was going to drive off the road (it actually scared me, and I dont scare easily). Weird thing is, it happens randomly when braking at high speeds.... some times it happened, sometimes it didn't.

Could this still be a warped rotor?

You could be suffering the death wobble induced by a brake problem.

What you are describing is what we in the Jeep community refer to as the "death wobble."

Yep. Warped rotors will give you pulsation. There's no tool that I know of to use, but you can definitely feel them when you brake if they are. As for getting death wobble? Look for and replace worn steering parts for starters.
