Solid axle vs Independent suspension

I know that older and current technology solid axle is much better off road then independent suspension. I've read and listened to many of the reasoning behind this, such as axle shafts weaker, more stress and wear, less travel, ect. What I'm wondering is if the materials and design of an independent suspension were made with the main purpose for off-roading could it be just as capable and reliable as a solid axle?

Sure it could. You could make a setup way better then a sfa but the cost would be super high.

H1's are. With their design it gets the diff up out of the way. Very good ground clearance down the center. Your trade off is higher cost and more maintenance, neither of which the military care about, they have money and people.

How much more cost is there comparatively?
Is there a way to build it to require relatively equal maintenance and durability?
Other then buggys and off-road specific applications like H1s is there a practical way to achieve it with current passenger vehicles? If so why don't they do it in vehicles like FJ Cruisers and H3s?

Going from solid axle to idenpendent suspension is a task that will take a lot of work and fabbing on something like a jeep.

I also believe that the H3 and FJ cruisers ARE independent suspension in the front but solid axle rears.

To make an IFS vehicle perform at or above the level of a SFA offroad (we're talking very slow trails, rocks, etc.), it would not be drivable on the street. The FJ Cruiser is a good compromise of a IFS vehicle that performs well offroad. With the anti-sway bars removed, a locker in the rear, and traction control/assist (all stock on some models) they'll keep right up there with a Rubicon for the most part.

IFS kills SFA for high speed desert running (Baja 1000).

LOL FJ

thinking about stock or near stock form if you are going to be high speed desert racing you need to look at the ford raptor. Doesn't get any better then that for offroad speed vehlicles. You still want IFS for it's dd ride smoothness and don't need raptor speed, look at the Jeep commander or GC. both are much better option IFS vehlicles then that turtle shell errrr FJ. They are the best comprimise of offroad capability and on road handiling available today. Slow speed offroad as we all know doesn't get any better then a Jeep with SFA. And as the years have gone on the on road comfort has gotten better for the now only made SFA vehlicle JK/JKU.

In the end it's all about what do you want in a vehlicle and what are you gonna use it for. In the end no matter how you look at it on road or off as long as your not running in the desert if you want endless smiles and don't think about the on road handling of sfa, ifs, or what ever other contraptions they have today, a JK/JKU will win out every time. Topless, doorless, wind in your face and sun beating down on ya. JK FTW
