Tandem axle spring seat & shaft, repair and upgrade?

I can definitely see how a crushed grease zerk or plug might be missed with all the road crud splashed up in that area. Thanks again, I will check mine

On the bottom where the old grease zerk goes is where I placed my relief valve. Now I grease it from the cap cover and don't have to worry about loosening any bolts.
