I found this but don't understand the values:
Shock absorber upper mounting
plate-to-frame nuts (M10) 48 35 and
Shock absorber-to-lower arm
bolt and nut (M20) 475 351

I'm doing the front struts and those are the values I need.

 

upper M10 bolt: tight.
lower big bolt M20: f...ing tight.


1st number: NM
2nd number ft/lbs


351 for the lower bolt is simply nuts! it's pretty much as thight as you can get it with a 18" long ratchet,

 

thanks
