Just and FYI, no more replacing Steering shafts for noise, even if you want a new one. Once stock runs out, we have to jump through hoops to get one shipped to us.

I have an '04 1/2 ton GMC Z71 CC, had shaft replaced at about 12k, just rolled 17k yesterday, and it's in the shop today for same problem. Wonder if they'll lube or replace in light of the new TSB?

I'll let you know how it goes...
