 2006 yukon makes a clunking noise when turning the wheel, vibration is also noticed when driving 65 mph. *ts a month after the vehicle was purchased the consumer started to noticed noises coming from the front end. the vehicle was taken to service dealer who determined that the upper and lower control arms needed to be replaced. after repairs of the control arm the vehicle started to vibrate. the vehicle was returned and they replaced the right front tire which they claimed was defective from the factory. one week later the consumer noticed a clunking noise in the front end. the vehicle was returned to the dealer who advised that the right rear upper and lower control arm were bad from the factory. the parts were ordered and replaced. when the vehicle was at the dealer being serviced the technician didn't cover the seat while working and got oil on the seat and steering wheel. the dealer replaced the entire seat with a seat on their lot. the consumer never authorized them to do that. now the seat is making a clunking noise. the vehicle was returned to the dealer who claimed that the seat is broken and that all the 2006 yukon denali seat are broken. the sear was taken apart and longer bolts were used to secured the seat. the seat is still broken. the dealer also replaced the steering wheel which is now making noise. the dealer said that the steering box needed to be replaced but that the replacement is noisier than the original. the dash has begun to peel. the dealer indicated that all yukon denali dashes are peeling. the dash was replaced with a new one. the engine sounds as is a lifter is off. the vehicle pulls to the left.
