Cannot remove front right tire for a flat - G6 Pontiac Cars & Trucks

caliper malfunction brake fluid leak onto the pads causing it to slip and smoking from the brake fluid burning

dunno for sure..

put the jack right under your passenger side door

Focus on replacing the two front tires with new. Have the car aligned and tires balanced. The mechanic will find and replace any defective front end parts with your permission. Be safe.

Tire hub is rusted to hub. use a mallet and hit rim from backside

You can remove the tire from the vehicle, make sure it is properly inflated, and spray with a soap and water solution. Carefully look around the bead, check the tread for bubbles, could be a puncture, and don't forget to look at the valve stem. Any bubbles indicates a leak. Good luck.

The lug nuts are the only thing holding the wheel on, aside from a little rust in some cases. Stand in front of the tire facing away from it, try giving it a swift kick on the edge. Of course, you must exercise caution when doing this. Be sure the vehicle is properly supported and won't fall the jack stand.

An easily overlooked problem that can have these symptoms is low tire pressure. Examine your tire for excessive wear or a flat spot. Check your tire pressures. If all this seems fine, rotate your tires to see if that helps the problem. If so, replace the suspect tire.

It could be wheel bearings/hub, ball joints, bent a-arms, or a-arm bushings. Good luck 

most probably a torn lower suspension arm rubber bush that would not show up if the car was on a 4 post hoist
there is a problem there as the noise would not be evident if there was nothing wrong
different tire pressures will give different noise when hit with a tire lever ( a trick used by truck drivers to check for flat/ under inflated tires
good tire solid sound
low pressure tire a dull sound
