Hey,
I'm just wondering what are some good choices for lower ball joints in north america? I've been looking into getting a set of Maxi ball joints, but I'm wondering if replacement is goign to be an issue in the future. Thanks

i imagine they will be available forever - maybe not always cheap, but always there

buy a few sets??????

Stating the obvious but if you are that worried, then buy a couple of sets, then you are fixed for the future.
