I dont konw Ive had cars with bad rotors at work that shook so bad you could barely hold onto the steering wheel.If it only happens on brtaking the rotors are junk for sue.After about 10 or 20000 brake jobs you learn.Im not saying that some steering cant be worn.But if it only happens on braking the rotors are JUNK.Then look at chassis parts when they get replaced.Reminds me of guys that turn new rotors and then say it shakes.No S--t.They are so thin new that cutting them just makes it worse.Rocky

It's almost impossible to buy a good quality rotor anymore. Even the 1 ton truck ones should be designed a 1/4" thicker than they are. Doesn't seem to matter if you buy the Dealer ones or the off-shore cheapies...they don't last worth s**t. Of course, people drive a lot faster now and tow heavier loads than they did 30 years ago when the problem wasn't so prevalent.
My wifes 07 Charger eats up front rotors like gasoline...of course, if you ever went for a drive with her, you'd soon know why !!!

Even the worst warped rotors I have dealt with didn't cause what sounds like a loss of control. That's a big gulf to jump from a shake to get to a dangerous loss of control.
EBC still makes a good rotor and Rockauto had some slotted China ones that have been OK so far. The EBC can be a pain sometimes to get in, so ordering from RA might be easiest if you need to get it done soon. My wife is a brake component tester and if they can stand up to her, they can stand up to you. I promise.
I want my fair share

SuperWrench you are right.I had more problems with the factory or hi buck rotors than the store brands.Carguy as for not creating a shake really bad you need to come to Ohio.Like I said in over 30 years I had some that felt like the whole car was coming apart.I had one Chrysler that I did new Bendix drums on the rear.Took it for a ride and they were so bad it almost threw me out of the seat.Yeah brakes can and will do crazy things.No matter how much you pay for rotors they are all the same thickness.Rocky

The fact is there are several reasons these trucks have death wobble... worn front end parts from trac bars to tie rod ends to brake rotors and a lot of time it is a combination of two or more factors and fixing any one can stop it for a while even if it is not the only participating part. After working on a bunch of them you can start to get an idea the difference in the various wobbles... warped rotors feel different than worn trac bars, a worn trac bar can start wobbling from a pot hole OR hitting the brakes, sometime swapping bars can fix it enough to not worry about the rotors, sometimes fixing the rotors can stop it even if the trac bar is bad. Usually if the trac bar is bad and the rotors are bad you can induce it from hitting the brakes but it probably will not stop just letting off the brakes, if you swap the trac bar in this case it may fix most of the problem but warrped rotors need to be fixed to get rid of it all, of course since it is way better the customer may let it slide that it shakes a little when you hit the brakes but that little shaking may cause the trac bar to go out early then you look stupid, of course if you fix the rotors it may quit for a while but come back soon, then you get blamed for using cheap rotors or machining them wrong... as a repair shop we pretty much have to go every component one at a time and recomend every questionable part to avoid a comeback, then they go to another shop who replaces rotors, the wobble goes away and we look stupid, but they are doomed to come back to us saying the other shops repair did not last.

You are probably right on this, but you forgot to mention a pee poor design. My 98 Ram 4x4 had the death wobble from the day it was new.

IIRC aftermarket makes a trac bar that eliminates the wobble.I know we did a few Jeeps at work that had bad bars.Rocky

If you got something made completely wrong, that is not the same as what you will see from warped parts caused by driving. Aside from running stock Yugo rotors on a Le Mans racer that is. Thickness has nothing to do with metal quality either.
