Calum does your new rose joint end have a grease point? The ones my car gained with the comfort kit had greasers but the replacements fitted by Revolutions in September dont which seems odd to me on a rose joint.
No, I got the PTFE lined ones which aren't supposed to be greased Apparently greasing can stop the PTFE getting picked up from the liner on to the ball so you end up with more friction and faster wear than if you leave them dry...according to the manufacturers anyway!
