This means that, after everything is reinstalled, you don’t have a messy brake bleeding job to do.
This is the wisdom that experience brings. Thanks, Bart!
It is easier to remove the sensor from the hub because the other end is actually inside the trunk, and there’s a bunch of other work involved to remove the sensor from the car.
Don’t be fooled, as a transmission jack is useful for more than just jacking a transmission. In this case, we will use the transmission jack to lower the entire subframe out of the car quickly and carefully as a unit.
Bart is extra careful (paranoid?), and he used a ratchet strap around the subframe to help secure it to the transmission jack. It’s just a little extra step that can help avert disaster if something goes wrong.
The rear subframe weighs a few hundred pounds with all the arms and differential and components attached. The car was balanced on the lift when it went up. When you suddenly remove a few hundred pounds from the rear end of the car, the weight balance shifts towards the front, and the car could fall off the lift. The screw jack takes any weight transfer and prevents that from happening. Yet another bit of wisdom from Bart.
