The upper ball joints on my ABS-equipped ’99 have seen better days; the boots are split and I’m hearing some clunking sounds. It seems I have three options:

  1. Buy new OEM ($$$)
  2. Buy used from a recycler (ABS arms are harder to find, and would be at least 12 years old…)
  3. Buy new from Mevotech or similar.

Who has experience specifically with Mevotech UCA’s for the NB miata? How’s the initial quality & fitment, and do they last? The price is attractive but I don’t want to install junk… I’ve used Mevotech swaybar endlinks before in a different application and they are holding up fine, but control arms are a bit more critical.

The car is driven in summer only, low total miles per year, but will attend the occasional autocross and/or track night (once I get a real roll bar).

I had the same conundrum with my '94 a couple of years ago. Joe Ramos, one of the techs at FlyinMiata recommended these:

I had my local machine shop press them in and tack weld them as Joe recommended. I've had no problems with them thus far... to be fair I only drive my car in the summer but I do autocross and track night it. I assume you could do the same with a '99... fairly sure the control arms are the same although I'd verify that to be sure.

Upper ball joints are different in the nb so you can't use the Moog replacements.
