Hi Bryan,I think I've had to replace fork seals on pretty much all the bikes I've owned. I had never done it on a telelever bike before, so Tony gave me a hand. Changing the seals is not that hard. You'd probably want to change the oil again while you're at it. You can do just one side. Yes, the plastic cover is the dust cover. You should be able to prise that off with a screwdriver. I am not familiar with the LT. A lot if stuff that's easily accessible on my bike could be hard to get at on yours. I think though that it should be possible to change the seal by just removing the lover half of the fork. You'd still need access to the top for refilling it. It may have a fill hole at the top, if not the cap needs to come off. Having said all that, Experience might just do it for you, or at least give you a new seal. Let them have a look at it.
