Heavy truck front suspensions:

Discuss why a heavy duty truck, let's say higher than 1 ton, can not/should not have an independent front suspension.

truck suspensions

The problem is that the geometry changes with load on an independent. where would you set the alignment? empty, half way, or to max GVW? I bought an 85 F350 HD that the alignment was set with a big cab over camper. I ran it only partally loaded pulling a trailer, the tires started to scuff and I had to have the twin I beam axles bent to get good tire wear and handling.

think today they could do it.. with the rig type air bag.. BUT
if a front air bag failed at any speed other than stopped.. with the truck loaded.. it be a mess..
also trucks that big are for work.. and it's K.I.S.S. (keep it simple stupid)
less parts= less upkeep cost..

I.c. but what about using a huge macpherson strut type setup? Or double A arms?

K.I.S.S. works best.

A long. long time ago double equal a arms were tried but the tire would stay perpendictular but move side to side on bumps.
