I've got a '99 4WD with the same stuttering. I searched up and down along the drive shaft and the whole power-train, can't find any grease fittings anywhere. My drive shaft has a rubber 'accordion' boot on the front end with some 'permanent' style metal banding for clamps. I'm sure this is where the male meets female, but do I dare cut off those clamps and mess with the boot? Will I find a zirx fitting under that boot? I felt around the boot, it doesn't seem like anything is sticking out, like a zirx. The drive shaft also had 2 quarter-sized circles attached to the shaft. Due to the level of rust on the shaft, I couldn't tell how they were fastened to the shaft. One at the back of the shaft top, on at the front bottom. I'm quite sure those are for balancing, not for lubrication though.
If anyone knows where I need to grease this slip yoke, please reply. And thanks to you in advance.
