Proper way to tighten struts

This is the proper way to tighten struts but without any special tools. The fancy socket there is a 13/16″ Sparkplug socket with the rubber insert removed. Turn the socket with the flats on the outsised using a wrench, in this case 7/8″ Now the tricky parts is using the 1/4″ drive 6 point socket to hold the strut top. A breaker bar would be better here but a ratchet will do just fine also. All these tools were in my basic Craftsman tool kit I have at home. This eliminates the risk of either damaging the strut mount by tearing it with turing torque or over-tightening the strut top. Also make sure to use the Koni supplied nut to hold the damper in the upright on the NG900/9-3. Using the original nut will ruin the damper. The new one tightens with a pin spanner and is commonly left loose causing noise. Hope this helps you.

“Too Tight.. Not warranty” This customers mechanic kept tightening the top nut to fix a clunk he caused by leaving the large lower nut loose that holds the damper in!

    For my ’97 900 set, I just got a 24 mm deep socket and a 1/2″ socket adapter (or it could be another socket that fits your torque wrench) welded at the local muffler shop for $5. Your price may vary!

    The 13/16 sparkplug socket is pretty loose over the 19mm top nut. A 3/4″ sparkplug socket fits that nut almost perfectly, but the 11mm socket will not fit inside the 3/4″ socket…

    Is it not a big deal how loose the 13/16 socket is on the 19mm nut ? I guess if you don’t want to torque it up too much it should hold enough before it starts to round off the edges…

    Or is something not right here?
