Have you cleaned your piston rods lately? We have found out that dirt and grime builds up on the rods and they make more noise and go up slower. What we do is spray the rods with silicon spray and wipe off with clean rag and then they go up very smoothly and little or no noise. We do not use WD-40 since it will attract dirt.
Also, we also start engine to allow the air bags to fill.
