My wife's 07 LTZ Tahoe is making a weird noise when going around corners. It sounds like it's coming from the rear axle, and it sounds like a muffled "honk". It's quite weird. Several times people in parking lots have told her that her horn honks when she turns, but it's not as loud as the horn, and it's coming from the rear. She does have the G80 option, but it's nothing like the clunk from a locker kicking in.

I know there is a similar TSB for Trailblazers and the fix is a whole new rear axle. Is there anything out there for the Tahoe's? Were taking it in for a new mirror soon, and I'd like them to look at this. I am just thinking they will blame the McGaughy's 2/3 drop as an easy out. Any info you guys have would be a huge help.

I had the same problem with my Denali. I took it to a driveline shop by my house and they said it was from driveshaft movement. The only remedy that they had was packing high nickel content grease in the yoke and reinstalling the driveshaft. Sounds crazy but it did work. Something about the metal makeup of the yoke that didn't allow it to slide freely.
