Do these fit over the straight axel hubs?

Willys Jeep Parts Tech:
See information on what all vehicles these fit.

What holds the dust cover on, does it clip over the washer between the nut, I have a dana44 rear axle in my CJ2A jeep

Willys Jeep Parts Tech:
It is tapped into place on a slip fit.

Will these fit a 1958 fc150?

Willys Jeep Parts Tech:
Yes, that is correct.

I have a cotter pin in the rear axle nut of my 47 CJ2a. Should I remove it or bend the pin to make it fit so that the dust cover fits over? Is the dust cover gently hammered on to install?

Willys Jeep Parts Tech:
Dont remove the cotter pin. Its there to keep the nut on. You just bend and put the dust cover on.

I ordered both these and and the rear axle washer for a Dana 44 tapered, however the dust cover does not fit over the washer. Am I missing something? Thanks in advance!

Willys Jeep Parts Tech:
Please take a picture of your washer you are using. You can email

Does the hub dust cover fit over the 4-wheel drive axle component that extends out from the wheel in front? In the picture it doesn't appear large enough.

Willys Tech:
Yes this is the proper dust cover for the original drive flanges in the front and hubs in the rear.

What is the measurement of the dust cover? Do they fit over the the entire 4wd hob (approx 4 1/4) or just the center part (about 2)?

Willys Tech:
These fit over just the center part just like original.
