I have a 06 Silverado 2500 4x4, 6.0, auto, with a bad vibration. A mechanic said there was a hole in the transfer case. I have read about pump rub. Just wondering if that might be causing the vibration also. It gets real bad around 60mph. Any advice would be greatly appreciated. Thank you in advance.

I am sorry you are experiencing this issue with your Silverado vehicle. Have you had the vehicle inspected for the vibration issue? Would you please PM me the last 8-digits of the VIN so I may check my resources for any known issues?

I look forward to your reply.

that is a great video.

GM has an updated retainer for under $20 that fixes the problem.

Mr Trans has a kit to fix the housing if its already rubbed through. Way cheaper than a new housing.
