GMC Serria Denalie
 

My 2002 Serria Denali( All Wheel Steer ) with towing package and has less than 60,000.00 miles and I have had my Trans axle seals replaced twice, once,both left and right. The second time the dealer only replaced one. According to my personal mech. , not the dealer. the trans axle should have been dismanled and checked then any necessary repairs sould have been brought to my attention on the first dealer repair. Has anyone else had this problem and how did you solve it.
