Hi there... new to the forum... Looks like lots of great info here! So I bought a 2004 LS180 with 6,100 hours on it. It seems pretty solid, and everything functions as far as I can tell, although a bit noisy. I believe this machine has changed hands several times now, and was originally a rental. Really have no idea how well it was maintained. No books or service records came with it. I found and downloaded the service manual, and have the operators manual on order. What would you guys suggest checking over before I start putting a lot of hours on this? Engine oil was just changed by the previous owner, but that's about it. I figured I would start with checking the hydraulic fluid level, and greasing all the zerks... but what else should I investigate or do to it?
