'90 Chevy S10, Sub-Zero Greasing & Urban Folklore
Q: I have a 90 Chevy S10 and have always done all my lubrication and oil changes. I was told by a friend that ball joints should not be greased at temperatures below 28 degrees or it could cause ball joint socket damage. Is this true?

A: The ball joints on vehicles operate under a tremendous load. In your case, the lower ball joints do the brunt of the work. I have never read or heard that ball joints should not be lubed or would be damaged when lubed below a specified temperature. Granted, the grease may not flow as well through the ball joint when servicing, but you have to keep in mind that the grease is designed to work with the ball joint at temperatures far below 28 degrees. I guess I would put that story in the urban folklore category.
