Hello. This is my first post here and I'm very happy to have found this group.
I own a GM8 that's apparently from the 90's. I've used it with autoguiding to take 5 minute exposures without problems and that's good enough for me. The tracking seem to be working well.
I'm gonna clean and relubricate the clutches (with Super lube as suggested by y'all) but I don't know what to do with the worm bearings. They look super greasy and dirty but I am very cautious since I don't want to do anything unnecessary as it is currently doing what it should. Here are the images of the RA and DEC worm bearings:

Should I worry about this or just let it be?
Thanks,
Fredrik
