WHY control arms wear so fast

[Lvangundy]

We're finding all sorts of solutions for the issues with the control arm bushings on the SC/LS but have we figured out why this happens? Any why is it that we're only discovering this problem on the SC/LS? Does it happen on the ES/RX/IS?

If might not even be something to really be concerned about since it could be a chassis design flaw..

My first guess would be that the V8 seems to have something to do with this, either in it's mounting position or weight, but I wouldn't think there would be much difference between the JZ engine.

the UZS131 crown has similar issues...... but being a castor rod type lower control arm/double wishbone job... its a little different.
