    One Bald Tire

    So... Bought 4 new tires Michelin pilot sports. rotated every month, balanced every other month. went to rotate today and found that my drivers side rear tire is bald. all the other tires are fine, about a quarter inch left of tread left on all the other tires. its worn like it was over inflated, but it was low, 28psi. any ideas what could cause this. i dont remember it being close to bald, or even to the indicators.

    it has just started making a brushing/slight grinding noise. its sounds more like something rubbing than anything else. ill pop the cover and change the fluid tomorrow and see if i see anything.

    Your differential is going out or you have a bearing going out causing the tire to have excess wear. Now would be a good time to see to it before something handgrenades.

    differential looks fine. had a few metal shavings on the magnet, but no chunks in the bottom or obvious cracks/worn teeth. checked the wheel bearings and they are still fine.

    Check your pass rear caliper. It may be sticking. My last car did that. Was FWD. Left front was OK but the RF tire was bald and I noticed the RF would spin from a stop. Turned out my LF caliper was frozen causing all the power to go to the RF and wear out the RF tire.

    what would be the best way to tell if a caliper is sticking?

    Put the car on a lift in neutral. Once in the air, spin either rear wheel. If one is difficult, or won't turn at all, there ya go. Stuck caliper.

    carefully feel the center of each wheel right after a drive.....if the one wheel is hot, or even much warmer than the other then jack it up and do the spin test.
    if its really sticking bad the wheel will get very hot and you might even have blueing on the rotor

    alright, last night i poped the cover off and checked everything out in there. this morning when i went out i found a second gasket. is there supposed to be 2 gaskets between the cover and case, or just 1.

    spun from the tire and driveshaft. didnt see anything cracked/worn. the ujoint did have a little play though.

    i didnt have a sticking caliper, both tires spun freely. i put my second worst tire on the back and am just going to burn em up. im going to get an alignment at school in the fall.

    hopefully the alignment will take care of it. when you swap tires, look at your rear tie rods just to be sure its not loose or bent
