Icon UCA/ballhead squeak

I have a 2010 with Icon suspension and for the last few weeks I've noticed a squeak coming from the bullhead that sits in the upper control arm. I sprayed it with grease and it solved it for a few days and now wondering what am I suppose to do as it keeps coming back. Is there a reservoir in that UCA?

 

I guess you could pop that cap off and pack it with bearing grease? Just a thought, Idk.
I have the camburg arms, they don't have a cap even and I'm in the saltbelt and the've done okay.
This winter might have got to them a bit, they've been making a little noise and seem to have a touch of corrosion but I just keep some wd-40 white lithium grease and a rag to clean them off in the back. Quiets them right up. I guess that just part of having race car parts on a dd is that they are maintenance intensive.

 

It has to be serviced regularly depending upon the environment you are in. Not sure where you are located, but moisture wrecks them. I believe there is a graphite or dry lube for them, but others will chime in here as I went with LR UCAs for this exact reason.

 

i use the triflow dry lube, does well, mine squeak really bad now nut i need to rebuild the balls on mine, maybe go to a shop and see if there is play in the ball? maybe its time for a rebuild

 

Yep. Tri flow should be applied regularly to the uniballs...

 

I live in S Florida, I was hesitant to take the ball cap off before I heard from someone with some knowledge about it. I'll try triflow tonight, until I can bring it to the shop next week to see about rebuilding them. Thanks for your input.
