I know this is a bit of a long shot diagnosing noises without hearing them in person but im trying to get some ideas of what it could be. About 2 weeks ago i started noticing a high pitched squeak coming from the passenger side rear of my jeep but the weird thing is it happens with movement of the jeep but when i apply the brakes or take a right hand turn and reduce load on the passenger side the noise disapears and comes back right after. I dont think its brakes since i just replaced them about a month or two ago. i havent gotten a chance to get underneath the jeep yet but plan on lifting the rear end up tomorrow and poking around.
