I didnt completely clean it so that could be. I just added more grease after the best inspection I could give with the tire off and the boot peeled back. The motor oil level is fine. I havent checked the front diff yet though. It usually only happens at 30mph or above under acceleration, when in 4hi. But pretty consistent in 4lo. Thanks for the input. I may have to call a Reno work meeting again soon. I know Beau and Bart both had things they wanted to get done.
