I’m starting to hear about leaky shocks. Can anyone confirm? How common is this? Just a little seeping at the top or rapid failure?

If installed improperly they are very sensitive to shaft damage. Scratching or etching the shaft will lead to leak. I have not seen or heard of any other failures at 3 HST events.

Which note?

I saw the one about the torquing of the shaft nut (only like 30# max) but was there another I might have missed?

I'm also curious about this note...

 

How would you torque the shaft nut without the shaft spinning and also not scratching it. I ended up holding the impact socket with my hand to engage the hammering action to get the nut down to the nylon.

i always learned to hold the shock shaft in your hand, and then impact it. should provide enough friction to get the impact hits.

I’ve always used a split piece of ~1” rubber hose and a pair of pliers, then wipe the shaft clean. Takes small hands to reach in there and hold it even if that were enough.

I use a piece of scrap serpentine belt, as the ribs give a higher point load to grip the shaft.

By using the method they suggested of holding the shaft with your had and using gun to tighten the nylon nut, lets say it turns over 2 or 3 times. that should not be enough to damage the shock, and if it is, then they need to redesign it as they will take much more abuse on the track.

Penske put out  a note that said hold shaft by hand only and use impact on the nyloc nut

Somewhere in here, there might be the elements of a funny joke about properly holding a shaft, rubbers, ribs and screwing around with nuts....   :tipsy:
