when i go to reverse and hit the peddle, i hear a clicking sound.. its really loud, and when i giver off the line it does it, but if i giver at a high speed like 30 or up it doesnt do it. also if i turn and giver it makes a clicking sound. so loud that my buddy could hear me and he was behing me a good 30 feet.. any guesses.. and i have a dinging sound with a lamp out indicator that intermidantly comes off and on, mostly when i hit my breaks. but no lights are out? could it be a sensor? or??????? if so how do i remove it and where is it?
