Re: 1/2 ton 4x4 vs 2wd rear-end

Just as simple as swapping the axles? Good to hear!

Re: 1/2 ton 4x4 vs 2wd rear-end

If the rear end your using in the 2wd is still good you could just change your Eaton diff, gears, maybe bearings instead of having to pull the axles from the truck unless I read wrong

It is absolutely NOT that easy. Installing a ring and pinion set is a very precise and specialized job. It isn't as simple as un-bolt and re-install into another housing. It will howl something fierce and fail very quickly.

Besides, you have to pull the axles to install gears, so you are not saving a thing.
