hokay, so, I installed some Warn premium hubs about a week ago since my auto hubs crapped out on me. today on my way to the mountains they started squeaking pretty good. I got on the dirt road and locked them in and they continued to squeak. When I installed them I didn't add any more grease than what came on them since I have heard that adding grease will cause them to not work. Right now they work fine but are sueaky as hell going down the road. Do I need to pull them out and give them a light coating or what?
