So I recently greased the chassis but couldn't get the front u joint on the rear driveshaft as the zero was pointing the wrong way. I yanked the driveshaft and got the front joint out, but I'll need to trim a little to get it back in. My attention then shifted to the cap that fell off the rear joint. I wiped down the joint itself and noticed this. So not much progress at all today. I bailed early so I could pick up a new wire cup brush and u joint for tomorrow. Fingers crossed I make actual progress.
