Default Switching 9" carriers for DD - insanity?

Is this insane or does it make sense.. Say you wanted nice low off-road gearing for your DD but diden't want to sacrifice gas miliage - if you had a 9" in the rear, you could have two carriers - one loaded with low off road gears (that match the front axle's) and one loaded with a higher street gears for DDing in 2wd?

If you wheel monthly, would it be worth all the work switching them to save (?) some dino juice.

Sounds like a waste to me, unless you really had a long way to drive. Anything that needs that big of gearing difference is going to suck gas down anyway...

If you were to do it, at least get full float setup to make it quicker to pull the axles.

But it'd be a waste.

Doesn't make sense to me. A lot of work, draining oil, stripping bolts, etc.

I have done it with my 8 3/4 in the TJ- pretty easy, and the open diff is much less annoying than the spool on the street w/o swaybars. :tonka:

Used to drive up to Great Lakes Dragaway in Union Grove with 3.23s in my old Challenger, and swap 4.88s in at the track. I could drop the exhaust, swap on slicks and change the rear diff in 20 minutes or less.

I want you to do it once, I bet you will never consider the idea again.

Just buy a tow rig and trailer. That shit sounds like work when you should be wheeling

Yup, floor jack, jackstands and electric impact.

The tires have to come off anyway for the carrier swap, and the exhaust ended at the rear axle. Pretty easy if you have swapped an 8 3/4 center as often as I have. I used to share a 4.56 center with my cousin's road Runner back when I was in my 'teens- I would get "visitation" every other weekeend. :tonka:

I swap my tires by hand, as well.

XJ D44s out of the boneyard with just a hacksaw and a pair of bolt cutters in under a half hour. :miff:
