For those that had the washers pull through, how did you originally tighten the first nut on top of the shock? Did you bottom it out at the end of threads like you are supposed to or just tighten it until the bushings started to compress? I'm wondering if they aren't tight enough it could cause play which would then allow a good jolt to pull them through??? I've had the Spax for nearly two years now and will inspect them soon to verify the washers still look good.
