I've got a SAAB 900 uprigths. May I replace the SAAB 900 Ball Joints:


Cone Diameter = 17.2
Cone Proportion = 1/8

with the Toyhota 4 Runner ones:


Cone Diameter = 17.1
Cone Proportion = 1/8

cheers,

Modesto

Tapper size looks much bigger

If the proportion is the same, and the diameter less, they might go too far into the uprights. I can't see any other reason why you could not replace them.

slightly stealing your thread here, how does that taper compare with the sierra upright ?

Sierra:




Cone Diameter = 14.1
Cone Proportion = 1/6
