Fastener question for engineering minds

[vabrzn]

I’m replacing the worn out stock shock with a Penske on a 2007 with ABS. The ABS modulator makes the top shock bolt removal a moderate pain due to clearance. There is a bushing in the shock mount on this side. Turning the bolt around would make the install and next removal easy. Is there an engineering reason the Head of the bolt would butt up against the bushing? Does it make any difference?

Thanks

The pic below is from WarChilds site; the ABS modulator prevents taking a decent picture on an ABS model. The right side has the bushing, left side does not.

I would say that it doesn't matter much which side the nut is on. In either orientation the tension in the bolt pulls the shock mount to the flange on left side of the bike. The bushing(right side frame flange) simply provides radial support of the bolt.

Make sure the bottom mount of the shock is attached to the relay arm before tightening the top shock mount. Once the top shock bolt is tight there isn't much motion available to allow alignment of the bottom end.

What FJReady said. The bushing is likely also there to prevent undo compression when the shock bolt is tightened. It makes no difference if it's on the nut or bolt side.

Makes sense to me. Thanks

Original orientation of the bolt/nut is most likely an assembly factor than anything else.

Much like on your car when you try to work on the motor these days.
