My 05 Dak has non greasable pivot points thruout. Lower ball joints are shot and are getting replaced. Hopefully the lowers are just shot because they take the brunt of the load and that the uppers and tie rod ends are OK.

I know they make a needle adapter to pierce the boot and fill with grease. I'm wondering if this is a good idea or bad?

I will have all that stuff disconnected and will try supplementing lubrication by sneaking the needle in between the boot and stud while they are disconnected but always wondered about puncturing the boots.

The new lower ball joints are Moog with grease fittings.
