Re: The Story Of A Suburban (Lots Of Pics)

Here is how I figured out what was vibrating in my Yukon. I drove it. And drove it, and drove it, and drove it... and then the problem shot through the diff cover. Hey! I found it!

Probably not the best troubleshooting method.

on a serious note... bring the truck up to operating temperature and check the exhaust for contact or miss-aligned hagers when expanded.

just one suggestion for now
