Hey guys just looking for some advice on what you think the problem is with my car. When driving my car it will start randomly vibrating for awhile then clear up and feel perfectly fine, i have noticed the front passenger wheel is getting hot and doesn't spin that freely (only a quarter turn) when lifted in the air. The vibrations will all the sudden start happening when crusing never just after or before braking, but will continue for awhile until all the sudden it clears up which is usually when i'm just driving normal and not in the process of braking. Based of research i think its the wheel hub, but would like to hear any input since i can't get it to the shop right away.

 

Hub issues are when you can rock it back and forth with A hand at the top of the wheel with little effort. This finds bearing issues too. Otherwise you could have a bad tire (my case).

 

Might also be a stuck caliper causing the pad to keep contact the rotor at all times. Check the sliding pins on that caliper and make sure they are allowing the caliper to "float" back and forth.

 

You would probably hear a bad bearing before you felt it. If it's a humming type of vibration rather than something that shakes your steering wheel, then it may be the bearing. Otherwise, it's probably a balance issue or a tread separation.

 

Well you've seen most of the possibilities now there's only one was to find out what the issue is. Take your G to a independent brake/alignment shop where they deal with vibrations 5 days a week from 8am to 6pm! My guess from what you described is a wasted caliper! Tire wouldn't make the rotor/caliper heat up and once you're in the air, bearings can be checked easily.
