Recently had the 8 3/4 rebuilt and upgraded to a 1350 size yoke (Yukon Brand). The driveshaft remained 7290 so I installed a 7290/1350 hybrid U-joint. Everything went together fine and during the startup/check, the wheels have a very noticeable hop once every rotation. Is there something I've missed during the install? I realize that's hard to determine since you have only one picture to go by. But changing the size of the yoke shouldn't have changed anything else. Your input is always...
Too Much Pinion?
