Took the truck into the dealer to find out what was wrong, they tried to tell me it needed all new ball joints--- $2600!!!!!!!!!!!!! heck no.
The Idler arm bracket bolts were loose & the idler arm was slopping around--the tech didn't see that.....for a $75 inspection you'd think theyd check more than ball joints.
Soooo I finally got around to looking into this steering column more & theres a joint in the steering shaft where the column tilts that is not serviceable like the '90's trucks. You have to buy a whole new column, which comes with new shift lever & turn signal lever.....book says 1.2hrs to swap out...
Part number is 15775845 .
CHECK EBAY!!! I got a new one for $380 shipped, dealer wanted $750.
1/3 loose idler arm bracket, 1/3 sloppy ball joints, 1/3 seering shaft has very substantial slop= loose steering

Ever need Gm parts and your stealership is a ass to deal with?
GO here:
http://parts.nalleygmc.com/productSearch.aspx
find the part numbers you need
google them
ebay search them
& buy the cheapest you find.....theres ALOT of surplus parts out there selling @ discount.
another tip---if the item is on ebay, typically if you call the seller, & buy over the phone with the credit card, they will cut you a discount because ebay/paypal fees rape them.
