Suspension arm torque settings (front and rear) help
I have tried searching and must be doing something wrong because I can't find any info even in DIY threads....
Does anyone know what ratings the bolts on the suspension arms are?
Front lower and thrust arms etc and all the parts that attach like roll bar ends and shocks etc?
And the rear arms too please?
Is there a download link for the workshop manual?

This information might be listed in the WIS but I am unsure. I have never accessed it and you do have to pay a small fee depending on the amount of time you wish to have access.

M14 bolts, 77 to 94 ft-lbs; I target 85 to split the difference. Max recommended torque for a Grade 8.8 is a little over 100 ft-lbs.
M12 bolts, I target 60 ft-lbs.
M10 bolts, I target 35 ft-lbs.
Measure across the shaft of the bolt, not across the flats of the head.
Above values can vary depending upon bolt grade; when in doubt, perform a search on "torque range metric bolts".
Clean, dry threads. If threads are lubed (as with thread locker) aim for the lower end of the torque range.
I use medium-duty Loc-tite on all joints where I cannot place a torque wrench.
If you have not paid to have your torque wrench calibrated in the last year or so, there are companies out there that can confirm calibration.
