For the guys that changed out the LCA arms did you also buy new bolts or re-use the factory ones. J&M states to use new hardware just curious.
If they are "one time use" that means the metal is stretched when torqued and thus should be thrown away. They aren't "fine" as ME32 suggests. They are fatigued by design and no longer good bolts.
I never re-use "one time use" designated suspension bolts...it's a safety issue. I don't want my junk failing because I was too cheap to drop $20 on a couple bolts.
There's a thread or two on this with a lot more engineer tech talk but that's the cliff notes version.
