I recently posted this question about finding the proper U-Joint for my truck (Chevrolet Silverado EC/SB 1500 4x4 Z71 LT3 L33). I'm planning on purchasing U-Joints which have zerks in them, so I can keep them greased on a regular basis. I know that the zerk should be placed on the compression side (on the clockwise from the input shaft as you'd be looking from the front of the vehicle back) to prevent problems with stress risers. My questions are:
- Does it matter whether the zerk is facing towards the front or the back of the vehicle?
- If changing multiple U-Joints, should they all be facing the same way, or does it matter?)
