Hello all, am a new member... and this is my first post. I am having problems with the intermediate steering shaft in my 02 Z-71 silverado 4x4 pickup. I had it replaced (they said they installed a "lube kit") at 9600 miles. Same symptems at 15k (and now out of warranty). G.M. tells me they are aware of this problem, but don't have a fix and say that there is no recall. I was interested to know if anyone else has had or is experiencing a similar problem and what they did or what the dealer told them. Truck has never been off road and is well taken care of. P.S.- does anyone know what the "lube kit" consists of? Did they replace a part or did they just grease it? HELP!
