What do you guys think this is? Need Some Help

It's not grease, it's rust. It looks like the car has been submerged at least to the axles, but it could be caused by a lot of things.

As per wheee!, I'd pull the rotor and inspect the bearings - it's been a long time since I saw that much rust in that area on a car. Might as well regrease while you're in there. Clean all the ferrous parts well and apply some high-temp paint (or a VERY light coat of grease) to everything that is not close to the rotor. Put it back together.

If you see any problems, especially with the bearing, I'd check the other three, too.

Thanks. The lack of noise or play/wobble made me think it's just rust also. Any ideas on the best product to use to remove rust?


....It just dawned on me that the last time I replaced the brake pads a little over a year ago I washed the inside of the wheels. I could have easily placed the wheel back on the car without letting it fully dry around that area.

If you're not going to paint, a wire brush ought to do the job. If you are going to paint, I'd use something like Naval Jelly (see also).

Well, that sounds a lot better than submersion. If you feel sure it was just "not quite dry" parts, you may want to forego pulling the rotors/bearings.
