I've been wondering about the same thing. After rebuilding my front suspension I wasn't able to get the grease to pass thru to the rubber grease boots on the back side (upper and control arms lower torque tube and cross shaft). I checked to be sure the bushing were not bottomed out on the shafts by removing the grease zerk and inserting a paper clip into the hole till it bottomed on the shaft. I tought maybe there has to be some wear on the theads of the shaft and bushings before the grease will make it thru. In my case both were new.It will be a while before mine is on the road. Maybe someday.
