Do you mean you can't just set ParamVel and ParamFMax on a ball joint?
You have to use an AMotor? I didn't know that.. don't remember seeing
it in the manual.

This post (1) on the ode list has code for user mode ball joints with
working limits (though I haven't tested it). (2) says there are some
problems though - it sounds like ODE only considers the limit in the
direction the joint is moving towards, instead of trying to satisfy
both limits at the same time.
