Torque setting for re-attaching rear shock?

Post by RickZ4 » Sun Oct 16, 2016 3:31 pm

Can anyone advise me what torque setting I should use when re-attaching my rear shock after replacing the broken coil spring..?

Thanks

100Nm.

But you have to tension it at normal driving position.
torque it down with the wheels down / in full droop will damage the shock rubber bushing.
So the wheels have to be sitting on the ground or the rear suspension trailing arm has to be jacked up.

On a 4 post ramp it's easy yes. (if you have a pit its also easy)
With 2 post ramp you need a transmission jack to jack up the rear trailing arm to get it somewhere in the driving position.
