I lubed them up with lithium grease! It should help! we shall see!!
The white lithium is fine and the darker it gets the more it indicates it is dirty and is time for a lube change. Once a year I remove my TUs for a through cleaning and adjustment. Do use a light machine oil (Plastic friendly like Wayne mentioned...thanks pal) for the TU shafts and bushings. Grease will NOT lube them.
