i have searched all over and have not found anything on this. i have a 2010 se cc 4x4 and when coming to a stop or going around 20mph i can hear a fast paced clumping noise, it gets slower as the truck slows. i have read that alot of you have u joint problems but my truck has only 4000mi. this sounds like a u joint to me. does anyone have this problem or have any ideas. sorry i am new here and already posted this in the new member section by mistake so i thought more people mite see my post here. this is my first nissan and i dont know if this is normal. i would like to have an idea before going to the dealer. any ideas would be a big help. thanks
