Hi, my name is Nat McCullough on behalf of Expert Village. In these clips, we're going
to talk about the proper way to remove and replace a front wheel drives vehicles ball
joint. In this clip, we're going to talk about the proper location for placing your floor
jack and jacking up the vehicle. What you're shooting for is the pinch weld or sub-frame
of the vehicle. The pinch weld is one of the strongest parts of the car. It's where they
establish a lot of the structural integrity. On this particular vehicle there are ground
affects in the way so you won't be able to see it. But what you're looking for is a sandwiched
piece of metal. It will be approximately an eighth inch thick. This is your vehicles pinch
weld. As you can see, I have my jack located right on it. Another or an alternate jacking
location is the vehicles sub-frame. Which is going to be this piece here. You can see
it runs a significant portion of the length of the body. That is another place where the
vehicles entire structure is built off of. Once you have your jack placed, you can go
ahead and take your jack handle. Make sure to tighten down the release screw and begin
jacking up the vehicle.
You can see as I'm working the floor jack, the vehicle is coming up off the ground. The
suspensions traveling. Once you have it high enough in the air, it's okay to go ahead and
place your jack stand. What you're looking for is just a very sturdy part of the vehicle.
It can either be control arm, sub-frame, or pinch weld. I'm going to slide this guy in
place. And I going to leave it on the jack and have my jack stand in place. Because two
things holding the vehicle in the air is better than one.
