Hello. My lca pivot shafts are a little bit bent, i have two spare shafts that also are a little bit bent. I have checked all the shafts for straightness in a lathe, and no one is straight. The straightness varies a bit between the shafts, when i put the control arm end of the shafts in a lathe, the threaded end is off by everything from 1,5 mm to about 3,2 mm (1/16" to 1/8") Is it normal for these shafts to have a slight bend, or should they be absolutely straight? Can the shafts be used, or do i have to realize that i need new ones?
