We have a 99' J200PLEEN (S#G04616679) with trim problems. It bounces on the way down. As others here have suggested, we have tried tightening the tilt tube nut and bleeding the system which did not change anything. One thing we noticed was going up, we couldn't hold it. It would lift us off the ground, but trimming down, we could hold it up. We spoke with a couple of shops and they said there are internal problems and we should replace the hydraulics. So, now we need the replacement hydraulic part. Can anyone recommend the best place to buy one?
