Disable front hubs?

[Gregsenne]

I have automatic hubs on my front axle, and I want to disable them so the axle doesnt spin with the tire.
I cant take the hub assembly out because then I dont have anything to bolt the hub cover to to keep crap out of it. Can I just take that spring out?

Im building a new front axle right now, but want to drive the truck until I get the new axle done. Theres no fluid or pinion seal in the diff, and don't want to ruin it by it turning going down the road. The driveshaft is already off but I know the axle can spin a little with the tires spinning, which is what I'm trying to prevent.

Thanks!
