after one year since i bought the yukon 2005 , started feeling knocking ,jerking, and seemy lose parts on steering on road , the agent dealer rpair shop replaced a small size greasing injuction kit by opning small bolt on the steering shaft somewher, then became excellent fine and smooth

after one year again 2008 happend again. when took the car to fix again in same dealer shop they stated sid GENRAL MOTORS don,t provide this grease injuction any moore, so i have to replace the complete steering shaft .and this will be repeated every single year year after year, does GMC know this? or what? if true. we will have to switch to other cars made
