Looking in to starting a new project and would like to put full size 79Ford Bronco axles (d44 and a 9")under a 97TJ. Would I HAVE TO cut the D44 down or could I leave it full width? I'd pefer to leave it alone if at all possible.

I do not know the exact widths, but there is one consideration to address.

Many states have restrictions on the amount of tire exposed outside the wheel well.

You might check the width measurements of the axles and determine how far they would extend past the body.

Then, check your local state regulations to see if it is within acceptable width.

Back up...

I am saying that you need to check with state vehicle code to see IF you are required to cut the axles down due to the amount of tire that will be exposed outside the wheel well.

If that is not an issue, there are a multitude of fitment issues to contend with.

Basically, the diff should sit in a known location in relation to the spring mounts. You will need to relocate the spring mount points.

As the wheels will be extended out, you will need to contend with extra length brake lines.

You may need extra trimming around the fender flares. If so, consider tube fenders to provide extra clearance.

What happens at full articulation??? Don't know. You may find extra trimming necessary...

I know of people that have trimmed their axles to bring the wheels in to create a narrow stance.

Full width axles are the norm with tubbed rock buggies; but not necessarily with a street legal vehicle.

Relocating the spring mounts is relatively easy. The extra length brake lines are fairly easy. The final articulation test for issues is the most time consuming --- unless you go full tube body...

O i understood about the spring mounts and the break lines but i wasnt sure about the steering and possible rubbing issues. How would i test for articulation issues. Its only 2.25" on each side you wouldnt think that it would be to much of a problem

The extra 2.25" may be a world of difference with respect to steering.

That is something I can't answer.

However, like I said, full width axles are the norm for rock buggies. They have solved that issue. But, they also do not have to contend with sheet metal placement in a stock TJ body.

If you keep the TJ body, you will need an articulation ramp (a fork lift is a semi-suitable substitute).

When you have the passenger front to its highest point with the driver side tire still on the ground, you will have max articulation.

At that point, does your passenger front tire touch sheet metal?

Now, reverse that test and see what max drop of driver side will do while determining if passenger side will touch sheet metal.

Like I said, tube fender solutions may be in the solution.

Now, it comes back to whether you want to build a rock buggy or do you desire to maintain street-legal configuration.

Check the state vehicle code to see if the 2.25 inches per side is within the allowed tire exposure limitations if you wish to drive it on public roads. Each state is different.

I have no doubt there is a steering solution available. Check with the vendors providing axles for rock buggies.

Your challenge is to ensure that your mods retain the ability to license the vehicle for use on public roads.

If that is not a concern, open your wallet as there are many vendors providing solutions. However, there are limited places where you can use your vehicle.
