Found some play in the drivers side lower ball joint on my '06 CDI. I'm also due for a pair of front struts. So I was going to replace lower ball joints on both sides on the car when I take the front end apart and get an alignment.

Looking online there is the Lemforder OEM version for around $26. There is also a "heavy duty" Meyle version for $40. I generally would prefer Lemforder over Meyle. Is there any good reason to go to the "HD" ones? I don't know what makes one ball joint heavier duty than another. The $28 difference for the pair is hardly a big deal, so if I really should do "HD" I am happy to spend the extra bucks, but I was curious if anyone could shed any light on this.
