Maintenance free ball joints

[tmsmini]

Anyone have an update on these after running them for awhile?
I put a set on a car over a year ago. The car maybe has a thousand miles since and there appears to be slight movement, very slight. Do you retorque these? I am having my doubts about them, if I can feel movement after 1000 miles. These are the Delta brand.

I've got a set to install on my car, but no road experience with them yet.....you might give them a shot of grease and see if that takes that slight movement out? I agree, as expensive as they are I'd be disappointed if they've worn in only 1000 miles.

Who sells the Delta brand?

I'd try to torque them and if they're sloppy, as in clunky up and down, I'd toss them in the trash. Are these firm to move when new?  Leather glove and hard to move with the palm of your hand firm?
