Knuckle Preload Shims - How to they work? (1 Viewer)

[Rocky_LC]

It would seem that having less shims would increase the preload, and adding more shims would reduce it - is this right?.

Do the shims space out the bearing retainers on the steering arm (top) and bearing cap (bottom)?

Or am I not clear on how the system works? An explanation would be appreciated. Thanks -

The shims set the preload and also center the inner axle in the housing. If it gets out of center, you'll blow your inner seal. The marlin hd seals are supposed to make up for a little off center.

Take a peek at the knuckle centering tool videos and instructions and it will help you understand how everything ties together.

I get all that (Thanks), but I am just asking: More shims, less preload, or more shims, more preload?

Thanks -

more shims = less preload.

Less shims more preload. Is right.

Thanks - It surely looks like that's how the geometry in the knuckle would work - just checking.
