I have a dumb question about U-Joints.
Spicer makes a bunch of models - the first being not greasable - fairly straight forward.
Then they make one with the grease fitting on the trunion. To me this would seem the most logical because it would be most likely to get new grease to all 4 caps.
The Spicer Life Series uses a grease fitting on one of the caps. Presumably this makes the trunion stronger, but I have these and it seems harder to get grease to all 4 bearings?
So for a mostly stock rig, which of these would be best / longest lasting. I suppose it doesn't really matter - all three will likely last a long time, but I am getting ready to do this again on my other rig and was wondering which to order.
Also, if your stock wouldn't you want your U-Joint to be the first thing to break before you broke something else in the drive train - a sacrificial anode so to speak, hence maybe the heavy duty Life Series aren't the best for that application?
