Bolts for front shocks
« on: 13 October 2018, 21:44:53 »

The two bolts that attach the steering knuckle to the front shocks, are they reusable?

Read on a Holden forum that they are "Stretch bolts" and that they should always be replaced. Is that true for Omegas too?


Thanks

Yes they are "stretch bolts" and yes they should be replaced if you ever have to remove them.

But virtually no-one ever does.

The bolts, if undamaged and clean, can be reused. Ideally the lock-nuts should be renewed if disturbed.

The lock-nuts are of the all metal thread distorting type where the top of the nut is deliberately deformed. In theory, once used such nuts can't be reliably re-tightened to the required torque prior to any further angle tightening. They are a use once component, in practice they are re-used.

That said if you disturb the struts you'll have to get the suspension geometry checked and reset. That might well require loosening and re-tightening to correct the camber. So if you do plan on replacing the nuts (and/or bolts) you could reuse your originals and ask the alignment shop to install the new.
