Bevel lock washer on sway bar link??

[JHZR2]

This:

FSM For 2008 MB ML 320 CDI doesn’t say an order.

The washer is far smaller than the nut diameter.

The ones on there, which are Mb parts have the washer against the ball, not the nut. That said, they are also in upside down as compared to what I’ve seen to be the correct installation. So…???

Where do I put the beveled lock washer??

FWIW, EPC shows it like this:

Conventional logic says to place the lock washer on the nut side since the goal is to keep the nut from rotating and backing off the stud. The ball and stud side is unlikely to rotate from vibration as compared to the nut.

I’d tend to agree. Though the lock nut is in use too. It’s not just like some random nut.

The way it sits looks weird of course.

Why do you call that nut a lock nut? I believe it is just a flange nut, whereas a lock nut would have serrations on the inner flange surface (see video below).

Yes, it would look normal if the lock washer was the same o.d. as the flange nut.

It’s the style of lock nut where the top few threads are a bit ovoid, and cinch the threads. As you engage more threads, it gets significantly harder because of the shape. I’ve seen ones like this before…

I’ve also seen ones where the inner flange is serrated. In fact, that’s why I figured the washer was a locking feature…

Got it, I usually call those interference thread style lock nuts. As shown on the video, they usually have a dimple mark on the side flats to denote they are interference threaded.

Honda uses them on sway bar links installed at the factory. Over time, they seize up where they will need to be destructively removed with a grinder or Sawzall. I have replaced SBLs on many Hondas and curse their lock nut choice every time!

The video called it a stover nut.

I just find it odd that thee would be such a small washer relative to the flange. I get it that most of the clamping would be at the flange on the ball shaft that is on the one side, against just the same circumference on the other side. But the gap still looks odd.
