I was out for a little cruise in the neighborhood and not far from home, as I approached an intersection for a major thoroughfare, I heard/felt a “pop” from the suspension. Alarmed, I pulled into a gas station to take a quick look-see. Nothing obvious was visible so I headed back home for a more thorough inspection, hearing another “pop” as I exited the gas station. Arriving at home I checked the front suspension points and found nothing loose or unusual. When I got down under the car to examine the rear suspension, I saw the driver-side radius rod missing a nut where it attaches to the frame. It is bolted to the frame bracket with a 5/8” grade 8 bolt. Upon closer inspection I saw that it was hanging on the bolt with only a couple of threads visible. Had it slid all the way off the bolt, the driver-side of my rear axle would have been located only by the coil-over shock, which wouldn’t do much to mitigate its fore/aft movement. Phew!!! That could have been a major catastrophe. Imagine cruising a major 4-lane thoroughfare when your rear axle decides to do the steering. I beat it up to the hardware store and purchased a pair of 5/8” – 11 nyloc nuts (one for each side). Why I didn’t use nylocs when I built it I don’t know. Moral of the story: doing a nut check once every Spring may not be enough. Be careful out there boys ‘n girls.


(PS - On the finished car the rear RR attachment points are not visible due to the 5" channel.)

Spanky, you'll be the death of me. Our cars get a lot of vibration and shock, and things do get loose. Nylocks are a cheap safety fix. And having more than a minimum of threads showing is another. And the Spring nut check is an annual bucket list item (is that a pun?)
 
If you want to take it up a notch you could dump the ny-locks and go for the "Flex-Top" lock nuts. Or some Steel Insert lock nuts. But it's not cheap!

And then there is also these.

But more affordable would be using a Castle nut.

I just realize that at those prices, that must be what they mean by giving your left nut!!!
Pun is most certainly intended!!!
