So to you, all independent front suspensions are the same. I think its pretty well understood that an IFS was done to improve the on-road driving experience over the P38, which it did. Was is a compromise that allowed more parts exposed to off-road damage, yes it was. Sounds like you want something with a live axle, a P38 or a Jeep. Hard to believe you broke a CV boot and it immediately cratered. Your boot was probably open for some time. CV boots, brakes, tires, come on, you know those are wear items. Sounds like you or previous owners have mistreated your transmissions. Again, since you think ZF's are crap, what should they have used?L322 front end is almost exactly the same as e38 or e39.
The cv failed in low range under engine braking. A piece of ice must have cut the boot.
