unless your rotors are cracked or been turned too many times i wouldnt replace them. you have to take them off to change them and most places will turn them for about $5 if you take them off yourself.

The rotors (especially the front rotors) generate a lot of heat to stop these nearly 4 ton monsters, Towing adds to the braking load, especially if your trailer brakes are marginal or not adjusted properly. Once overheated, it doesn't take much to cause the rotors to cool unevenly and warp a little.
Some brake shops will turn down the rotor to make the surfaces parallel, but I shy away from that based on the reasoning that if the rotor warped when it was X thick, X minus 40 thousands of an inch will warp a little easier next time.

Been reading a lot about the shake, bump steering issue " or what ever ya wanna call it"
the other day I noticed while in reverse and foot lightly on brake pedal I hear a little noise like every time the wheel goes to that spot.
wondering how do you tell if the rotors are warped ?
thanks

I set of Brembo's replacement rotors will work also for alot less money....less that stock! (Pic is of a 1/2 ton but way beefier than stock.)

I work on alot of E-series vans that have commercial accounts with the shop I work for and they generate that problem alot when the van is loaded and driven daily. Some are worse than others but they just don't like braking at highway speeds.
