not sure how everyone has problems with the RC joints and disconnects, im over 10k miles now and not one clunk, i do keep them well greased, and ive been thru 3+ feet of water at OFR, to 3 feet of mud at Mettowee, and nearly 2 dozen wheelin trips in between and never one clunk, although u know when they need more grease, because they will make a slight squeaking or pop sound, but long as u grease them plenty the should never wear and cause clunking, but if they do, just buy some new inserts from iro or clayton like i plan on doing when they do wear, because they use a stiffer compund that will last longer, but u still need to keep them greased
Now for the disconnects, i did start to get a slight clunk from one of them after a week, but i stopped keeping them sprayed with this spray lithium grease i have, and after the rubber swelled ive not had a clunk since, now i just spray the inside of the rubber insert, and now clunk free for over 10k miles!
