Alert me when someone posts in this thread:

I bet the Moog joint is fine, with the following caveat:

Many people swear the one-piece joints are stronger, especially because the ball is mainly pushed into the socket by the weight of the car, since the springs are on the top control arm.

The one-piece joints are smushed together around the orifice from whence the ball shaft protrudes, probably with large forging dies. I know this because I have seen a one-piece joint all shot to hell, and the ball definitely could not be removed, despite having no lubrication and about 1/4" of play.

European cars often had the spring on the upper control arm (a Jaguar invention, I am told), so the ball would be pushed into the upper joint, hence the one-piece joints being superior for this application. Old RWD American cars often had the spring on the lower control arm, so the ball would be pulled up from the lower joint by the weight of the car. Thus, the Moog joint might be better for this application, the ball not pulling against the weak point (the ball having been inserted from the back side and capped with stamped sheet metal). This difference probably is the reason for the one-piece joints being called "Euro-style" and made by Europeans like Lemfoerder and TRW, while the ones like the Moog one you have are referred to as "American-style".

The one-piece joints are therefore probably better for Saabs, on the upper control arm. The lower ones seem to fail more on my Saabs, but probably from lateral loads. I'd be interested in trying a Moog or other "good quality" American style joint down there to see how it goes.
