I have recently got a vibration in my 04 Yukon Denali at 70-80 mph, especially when I let off the throttle. I immediately suspected U-joints, so I bought four spicer greasable U-joints. When I went to remove the front driveshaft, I noticed that when I pushed up on the U-joint near the transfer case there was some play in it. Upon further inspection, the play is NOT in the U-joint, it is in the front output shaft. I estimate the play to be somewhere around 1/8-1/4" vertically. Also, when I twist the driveshaft back and forth, the transfer case is making kind of a clunking sound, and it turns probably 45-60 degrees between where it stops in either direction, which seemed kind of excessive to me.
Has anyone had any experience with these AWD transfer cases, and know if that output shaft play is normal or not? The truck has around 135k miles on it, and the fluid is full up to the fill plug. Thanks in advance for any help with this.
