How do you replace the lower ball joints on a 1979 Toyota Cressida?

To replace the lower ball joints on a 1979 Toyota Cressida, first lift the vehicle and secure it on jack stands. Remove the wheel, then detach the brake caliper and rotor to access the lower control arm. Unbolt the ball joint from the control arm and the steering knuckle, using a ball joint separator if necessary. Install the new ball joint by reversing the removal process, ensuring everything is torqued to specifications before reassembling the brake components and wheel.
