Is there a fix for extremely squeaky heim joints??

I have the billet UCA, my ubj are worn and are very loud, I know there is a maintanince part for that, but my heim joints are just as loud I have cleaned and sprayed cans of Teflon , tried graphite and pfte spray, nothing works. They only stop making noise after I wash the truck and that only lasts a day. What can I do? Do I have to disassemble the whole thing that would cost a lot to have a shop do.

 

Use Tri-Flow

 

The reason the tend to make noise is because the rubber bushings and washers are not lubed enough, I loosen the Long straight bolt and put some grease between both then I retighten, pumping grease through the fittings doesn't always work
