There is a pin that goes up through my spring pack and goes in to the axle pad. I am assuming it is an alignment pin to make sure the axle stays in the right spot on the springs. This broke so I had it replaced. Now I have to put in a 2 degree shim because they welded my new spring pads in the wrong spot. When I put this shim in the pin only sticks up about 1/8 inch past the shim. so only 1/8 " is going into the axle pad. Is this OK? I don't want to get under some torque and my axle get loose.
