I have a clicking sound coming from the rear area of my truck and it always starts at low speeds and when making a right turn. I have read over the forums and narrowed the problem down to either a bad u-joint or the e-brake (I have rear disc brakes). I don't think it is a u-joint because I have had them go on me before on other trucks. The truck usually has a vibration at highway speed when they go and click when in reverse also...This truck doesn't do the click thing in reverse and no vibration at hwy speeds. I am going on a trip this weekend and was wondering if I would damage anything if it is the e-brake problem?
