Re: [Chrysler300] 300 ball joints - clean 'em or toss 'em ?

[Gary Nelson <garythepartsdoc@xxxxxxxxxxxx>]

Hi John and all

A ball joint has life if it does not flop around. A simple test is hold the 
joint by the head with the taper pin horizontal. If the pin remains 
horizontal and does not drop then there is enough tension to use. (my 
opinion).
As far as media blasting you absolutely cannot allow media to enter the 
joint. I have used duct tape up about 1/2" on the radius that the rubber 
seal rides on. The tape must cover the entire base of head and all of the 
tapered pin. Then you can blast, clean and paint before removing tape. Hope 
that helps.
