I dont know much about my rear end and brakes, but i know something is wrong back there. When brake, it feels like a warped rotor when i brake. At first i thought my rotors were warped in the front, so i replaced them with nice cross drilled and slotted ones and a set of new pads. this still didnt fix the problem. It sometimes doesn't surge/wabble when i brake which tells me that it isnt a warped rotor because its not doing it all of the time. i think it might be my alxe or something like that cuz its making a noticable whining noise (which has been there since i bought it...15,000 miles ago). but now its a little louder sometimes... it seems. I shook my rear tire hard trying to figure out if its just a loose tire, but when i shook it really hard, i had play somewhere in the axle and it clunked. i checked the rotors and tires and they are tight. What could this be. bearings somewhere? It also seems out of alignment sometimes and pulls to one side or the other when on uneven ground. Oh and the inside tire's axle also pops when i turn a corner and give it some juice like its slipping. any ideas? thanks for the help!
