    Hey , I used to have a Wrangler that did the same thing! The dealership told me that my brake rotors were warped and needed to be machined to resurface them and that my tires were chopped (they had worn unevenly) and I was told that this was a pretty common problem on Wranglers. Hope this made sense.

    Your rotors are warped like many 2000 Grand Cherokees .. there is a class action suit against DC regarding this issue .... thousands of people have had their rotors replaced several times ... only to find out that nothing helps. They have an upgrade kit available to help which I have paid to have done but it only prolongs the life of the rotors about 50%. I'm still looking at replacing rotors about every 2 years ... it was about every 9-12 months before I had the AKEBONO brand upgrade installed by the dealership. The brakes are simple not made well they tend to pinch at the end of the pad leaving small indents which cause the pads to grab there more and make hot spots ... then the hot spots make your rotors warp. If they used better calipers and stiffer supports it wouldn't be a problem. If you love your Jeep and can't stand unreliable brakes then check this site out. I think this is my next step as well ( http://www.vancopbs.com/product_p/dkj1000.htm ) It's an expensive solution but maybe when we Jeep owners win the lawsuit against DC we will get enough money to get the kit and make it right!

    BTW: I see alot of people saying to have your rotors turned and while this might be okay for most cars, Don't do it! When you turn your rotors you are shaving off material ... and the thinner your rotor gets the less heat it can shed .... do the math they will just warp again at WARP SPEED! You'd be better off buying cheap rotors and replacing them every 8000miles then having them turned and running into the same problem again only faster!

    Hi, i would totally agree you have warped brake Rotarys, I would take it to a good front end/brake shop have them check/ do a good brake job on front, replace the rotars etc.. also if you have oversize tires this can also begin over time to cause lots of wear to your front end etc.. my recomendations after all this would be the brakes, rotate/ and balance tires, check all of your universal joints etc. also ( worn universal joints would give you some shaking and abnormal start offs, gear changes, stops etc.. do your self a favor check it all while its in shop, You can actually check your U.Joints your self very easily done, My 3 yr old could do it . have them check and do a front end alignment also. the shaking could be caused more damage if its been ignored and driven with such for long periods. Good luck, and take it all seriuosly, its your safety ... If i can assist in anyway contact me via email.

    You probably need a front brake job because your front rotors are warped. The wheel lug nuts have to be torqued correctly and evenly to help prevent the problem in the future.

    if you're going downhill how is the road flat? Anyway i second the warped rotor suggestion. You may also have loose bushings somewhere.

    I had this problem and upgraded to the premium rotors and premium brake pads that Napa autoparts was carrying. Its been 4 months now and no more vibration under braking. I heard the Akebono route but I think that the problem lies in the cheap rotor metals they use, and rotors work by pinching so I don't understand that argument. The premium rotors have better cooling from vent holes drilled on the surface and are made out of a harder metal.

    Well the brakes work great now!

    Remember: You get what you pay for!

    Good Luck

    Check your front rotors. They may need to be turned. Or maybe they were turned and need to be turned back. Or you may need new rotors.

    The famous "death wobble" huh?? It's either going to be your rotors or your steering stabilizer shock.
