1995 Jeep Grand Cherokee Rim/hub/lugs

I'd have this looked at right away at a tire and alignment shop. I'm having a hard time visualizing this, but if the wheel is moving in relation to the rotor, it's possible the wheel was loose and the lug nut holes are wobbled out. That will prevent it from being clamped tightly even though the lug nuts are tight.

If the mechanic finds you need a new wheel, lug nuts, and studs, you can avoid similar problems in the future by always using a click-type torque wrench on the lug nuts. All shops have wall charts showing the torque value for all car models with steel and cast wheels. All professionals use torque wrenches too. They will tell you the proper value for your vehicle. 95 foot pounds was real common on most Chrysler cars with steel wheels. Trucks and Jeeps were a little higher. Cars with cast wheels usually called for 80 foot pounds.
