GMC Yukon Problem
Visitor, 2001 GMC Yukon
I have a 2001 Yukon and I have a clunking noise is my steering shaft. this is the same problem I have had fixed 3 times. The first was under factory warranty, secound I did myself (it was easy). The third was done under the extended warranty. It now has 150,000 plus miles and needs it done again.

Dealer said "not a safety issue, so people usually just leave it." Had them replace it before I bought it, then they discovered a RF hub needed to be replaced. I thought I felt something ~else~ clunking down there... good thing they gave it to us for the weekend for an extended test drive! :D
