Is there away to add too much grease to the kingpins and universals? Should I push old grease out until I see new grease? Typically on tractors this is what we do, air-gun-grease until we see fresh grease coming out of the pins. I didn't know if this would damage things on my truck.

no you should grease until you see new grease pushing out

There is a happy medium on the universals. Too much can make the seals fail.
