does anyone know the size of/ where i can obtain a *quality* replacement for part number 99940-1001? its the nut for the swaybar mounts.
took the car for a spin yesterday and it felt...saggy. checked around and the nut for the right rear swaybar mount is gone. It's the one labeled 2 in the diagram. i believe it to be a 9mm but not sure. i know an 8mm is too small and the 10mm is too big and i was lucky enough to forget my sockets at home.

 

I just had them off a couple weeks ago but don't have any idea what the threads were. If it was me, I'd drive it to a local autoparts store and try different nuts until you find one with the right threads. I'm sure there are better options but that would my first attempt.

 

Did you try Ray Crowe? or Mazda? or Mazda Motorsports?

 

Your local Mazda dealer should have them.they are a commodity item used just about all sway bar links on all models of Mazda

 

Fairly common part, I have them instock at my dealer. There is a supersession however. The new number is 9994-01-000. Problem solved

 

yup, got one yesterday. swaybar action is back!
