2004 GMC Yukon V8 All Wheel Drive Automatic 128000 miles
3 months ago, a repair shop said that my Pitmen Arm should be replaced. They used a part number K6536.
On last months trip, my all wheel drive Denali rear end swayed out 30 degrees on a quiet, slow wet turn. The Cadillac dealer said my tires were too worn; I replaced them with OEM Goodyears.
The problem seems to continue. Here in Prescott, AZ, I had the Cadillac dealer service the rear differential which they concluded, upon disassembly, was a bit sticky.
The problem seems to persist; the rear end seems to take an extra movement in any turns - usually.
I think my next step would be to have the dealer check that the correct Pitman Arm is installed and then service the mid body transfer case.
