Changing Rear Shock Absorbers. Astra-J Hatch. Replace or reuse bottom bolts?

[Big Dave2]

Hi folks,

I'm about to change the rear shocks on my car, and according to the info on the Vauxhall workshop manuals website the bottom bolt that connects the shock to the suspension arm should not be reused, but a new one fitted.

The torque settings given are to tighten initially to 150 Nm, and then tighten a further 65 degrees. This suggests to me that it's a stretch bolt. Am I correct?

In all the years I've replaced shock absorbers on various Vauxhall cars, this is the first time I've ever seen mention of replacing the bolts.

So, do I throw caution to the wind and just reuse the bolts, making sure they're FT, and a bit of thread lock for good measure.

Or should I replace them as suggested?

Thanks.
