ZZ Top aside, I’m cleaning up the Cush drive on my Cali project and seeking some answers/input here. Today I was able to remove the plate to get at the pucks and such underneath but I had to apply heat, spray lube, and a tire iron for leverage to get it off. Pictured here is the “stem” and the cover. Some questions.
1) What should I use to clean those parts up? I first sprayed some brake cleaner to try and remove the orange corrosion, then wd-40. Those “kinda” helped as the pictures you see here are after I hit them.
2) When I put it all back together I assume I use a good bit of grease on most all parts?
3) I drilled all the pucks and I have plans to install them all - not half of them as Field and others recommend - but should I put some kind of rubber spray lube on them as well to try and keep them from drying out?
4) I’ve drawn a couple red lines on the inside of the Cush cover that goes over the bearing stem. What are these grooves? They seem to circle the inside and even cross at a couple points? What do they do? Are they intentional or something that maybe happened from wear?

The groove in hub is to retain grease so it keeps moving. Might last 6mo if lucky. Most rust back up.
I don't do anything to rubbers, clean them off.
Those hubs are NLA from US importer, holds the bearings. Some folks want big money, can get them in EU.

There will be differing opinions on this! I use half the rubbers undrilled, I lube the rubbers, I don't think it matters with what, I lube the bearing shaft and collar with whatever I lube the splines with, Wirth at this time. I have used 3M silicone lube on the rubbers not a lot just so they're slick, no extra. I was truly impressed with the change in behavior the first time I did this. Upshifts were much less harsh and down shifts were much smoother feeling. Might be some confirmation bias in there but there you have it. Obviously YMMV!!

I usually wash the rubbers in hot soapy water, dry ‘‘em and spray them with heavy duty silicone spray
