Royal Star final drive.
Hey all. New to the forum but glad to be here. I have a 97' Royal Star Palomino I acquired about 6 months ago, was sitting in a garage for 8 years and only had 4k miles on it. Got it up and running but recently the final drive started squeaking/almost like a rub at a certain point when it rolls. I did put new tires and Yamalubed all splines and made sure the hub pins were clean and lubed too. Aligned it to the best I could and ran fine for about a month until recently. I did check the final drive oil (80w-90) and noticed the oil looked fine and clear but when I shined a light on it, had an almost metallic shine to it. Is that normal from microscopic metal shavings off the gears?
