my wife drove the truck for the three years we owned it .it was a 2006 bought in march of 2007 with 7 miles on it.truck was driven on average about 10 miles a day never off road.big snow storm in feb 2010 truck was terrible in snow but attributed to worn michelins.the truck clunk when put into 4 wheel but really no sign of major problem.truck was serviced in oct of 09 for tie rod check so the front end was looked at also tranny was check because of slow response time when cold..I started driving truck to work with about 38000 on it 50 miles aday when i noticed problem.took to dealer and both front axle u joints are wiped out plus ball joints on one side.there is no drive train warranty for this truck and at this time .they will not work with me even though i believe it was an existing defect and want 1200.00 to fix
