the dealer where I bought the truck lubed the i-shaft and the problem went away for about two miles,then returned on the next bump in the road. GM dealer 'found' the problem before the truck was on the lift and quoted $200.00 to fix. I got under the truck and twisted the steering column by hand and found the noise coming from the steering box. The ASE mechanic that lives next door said there was no way the noise could be coming from there. Googled the problem and got directions on how to reset the backlash in the box. All I needed was a 5/8" open-ended wrench and a 3/16" allen wrench and about 20 minutes of time.
Original owner - steering column has been repaired at least 2X and is again thumping. This has been a recurring problem since 2004. While GM is boasting about their 100th anniversary, it's astounding they still haven't figured out how to design & build a steering column.
I love my Suburban, but the loose knock in the steering makes an otherwise stout vehicle feel rickety. Am taking the suggestion of another poster and inquiring about a replacement shaft at a local dealership.
Added a grease zert to the spline shaft of short shaft coming out of firewall. Stopped the rattle, however the slack is still faintly
there. The grease will work out and probably rattle again.
Chevy does now have a replacement shaft, approx. $110, per my contact at the dealer. The shaft connection up in the firewall was not really visible, so I'd probably have them do the installation.
Not a Re-Call item, I guess since it's not a safety issue. My rattle was getting greater all the time, and would soon be worth $200 to remove. I got this truck last August and have added only 5,000 miles. Probably been lubed before, since a nut was missing on the boot.
Knocking in steering when when in a turn left or right. Dealer says known defect but no replacement part available. They say drill in a zerk grease fitting and "grease the crap out of it"
