I have a 99SE. When I got 2 tires changed, I had them rotated so that the new ones(Dunlop SP w-10's) are in the back and the unworn older tires originally in the back are up front.later the very same day, I noticed a slight thumping noise when slowing to a stop like "thump thump thump" as if one of the tires were uneven, but it only occurs at relatively slow speeds. I went back to JustTires and they said the rear rotors were uneven in thickness and needed replacement along with the pads. The mechanic even showed me the measuring device used to indicate the thickness of the rotor to convince me. The replacement took care of it for a couple days, but now I notice the thumping sound gradually coming back again at low speeds (0-25mph)! does anyone know what else it could be? thanks

 

Rotors which are "uneven in thickness" usually manifest themselves as a pulsating feeling in the brake pedal. The symptom you report is a noise, not a feeling. Here are some ideas for diagnosing the problem.

1) Verify that tire pressure is correct, all around.

2) Verify that all wheel nuts are correctly torqued (80 foot-pounds).

Road test the vehicle. If the symptom persists the Spotlight Of Suspicion falls on those new tires. Do you have a friend who drives a 4Gen or 5Gen Maxima? Perhaps you can exchange wheels with him for an hour. Put two of his wheels on your rear, in place of those new Dunlops. Road test. Put two of his wheels on your front, in place of your old tires. Road test. The results of this experiment should identify the source of the noise... if it is from the tires.

 

I dont know any other max owners but wish I did! but Ill try to ask for a warranty replacement tomorrow anyways. Thanks for the help Dan!!
