I drilled and tapped all the joints for grease fittings and pumped in silicone to free it and eliminate the noise. Nothing against them but it has far less to do with racing than it does time. Time will displace the grease as will moisture.

Just saying, I've been there and done that and it's why mine has RC-F LCAB....

Hey we learn from our own or better yet other people's mistakes as they don't cost us a dime
