Mike is quite correct. With Mfrs trying to queeze every penny of cost and
ounce of weight out of their products, realtively heavy items like brake
rotors have been marginalized for years, to the point now many of them are
inadequate in evern the best of circumstances. Jeep SUVs have been notorious
for this condition for years and DC has had several service actions to
address the issue on YJ/TJ/XJ/WJ and ZJ. In all cases they insist the wheels
be torqued evenly, but most shops just wail away with the impact wrench.


The best bet on a late Cherokee is to source iron rotors from NAPA or other
aftermarket outfit, forget the factory units. However, be certain to ask for
iron, not composite rotors. They may act confused over this, but if theh
sell you composite rotors you'll have thumping brakes again in short order.
