ball joints greasing how

hello all, i need to add more grease into my ball joints, i also heard i need a needle to stick it into?! and does any one have pictures of what i need to add grease to ball joints!?

thanks

 

If the balljoint doesn't have a grease zerk on it....standard or needle zerk fitting, then its not a servicable balljoint. It's a closed unit and not meant to be greased.

By sticking a needle in there (the boot area) - you're only sacrificing the integrity of the boot and pushing the boot out of its position thus making it less likely to function properly and less likely to get the grease exactly where it needs to be.
