UCA grease boots are leaking. How do I fix?

Hey everyone,
I was checking out the front suspension today and noticed that the rubber grease boots on the stock UCA uniball are leaking grease. The truck has a 2.5 lift with billy 5100's. Do I have to get new boots entirely or is there a way to refill the grease in there?

Thanks

 

bump...has anyone dealt with this problem before?

 

Just make sure they dont run out and they Will be fine

 

I'd just wait until they develop play and then replace the whole thing, not really a way to replace only the boots.

You can use a needle adapter to pump in fresh grease though, if you do that just wait until you lose a bunch.

 

Ok thanks a lot! Know what type of grease I need?

 

I should say if you can see just a tiny hole you could clean the outside with some brake cleen and then hit the hole with some RTV.

If you elect to use a needle adapter I'd use any grease you'd use in your u-joints. It's not so much as what you use but that they stay cleanly lubed. Any contamination will quickly create wear and thusly slop as would running them dry.
