Tapping noise

manimal · September 23, 2005

I bought my 96 Yukon a year ago with 160,000 miles on it. I rearly use it, Ive put 2000 miles on it this year. She runs great, all I had to do was switch out the shocks. I replaced the plugs and wires and all the belts.

After I replashed the shocks I started getting this tapping sound that comes and goes. I can go days without hearing a thing then when I hit a bump I will hear a tapping sound as if something is loose. I only hear it when I step on the gas, if I take my foot off the gas the tapping stops. And I can only hear it when Im driving under 30mph. It only happens for a few minutes then its gone and I wont hear it for days until I hit another little bump. I cannot pin point were the noise is coming from. 1st I hear it from the front of the car and then in the middle. Im just not very familiar with the mechanics of the Yukon.

I plan on taking the Yukon to a mechanic but I dont want to get stuck with one of those guys that says "it could be this" and then charges me to fix something that isnt broken. I want to be able to direct him to the problem. Someone told me that I might have a loose shock, another said to check my U joints (geez I have no idea what a U joint is).

Any help and or suggestions will be greatly appreciated.
