Raised each of the TT's wheels with a Trailer Aid Plus
(works great BTW), and pumped new Lucas Red N Tacky through the hubs. Did not disassemble them since we purchased it just last September, but did give each wheel a shake to check adjustment and they all seemed fine.
Cleaned the WD hitch rub points with a drill mounted wire brush, then sprayed them all with Satin Black Rustoleum then EZ-Slide
Graphite Based Coating. Haven't used this before so we'll see how I like it, goal would be to reduce noise without grease.
