2007 Audi A3 Quattro Front Driver Side Lower Ball Joint TRQ PSA66130

Hi, I’m Mike from 1A Auto. We’ve been selling auto parts for over 30 years!

All right, so we're going to take the tire off. On most Volkswagens there's little caps that go over these lugs. And the caps, you're going to need the tool from the spare tire kit. You will put in and grab, it's like a hook, and you'll pull the cap out. But this vehicle does not have those on currently. So we're just going to loosen up the lugs with a 17mm socket and a breaker bar. One at a time, just a little bit.

The reason I'm jacking this vehicle, you're not going to want to use a jack or jack stands on here on the control arms or on this aluminum because you may break the aluminum. Or there. Some places you can jack up from, just over here where the pinch weld is. On this Volkswagen you can see there is specific spots where you're supposed to jack the vehicle or support the vehicle. These little arrows indicate that. And right on the pinch weld is the strongest part to be jacking and supporting. Same over here. This side. This little arrow pointing down. This one looks like it got smashed a little bit.

So we're going to take off the lugs. Volkswagen has lug bolts, not lug nuts, or lug studs. So you need to be careful when pulling off the wheel. Then you grab the wheel and set it down. Next, we're going to separate the ball joint from the control arm. We're going to use the 16mm deep socket and the extension and a ratchet. All right, we're going to loosen up the upper ball joint nut. It's an 18MM wrench. Now we're going to use a pry bar. Try to separate the ball joint from the knuckle.

If you're struggling, sometimes a fork will help get the ball joint out, especially if you're not going to reuse it, because it will probably mess up the rubber boot. So, because the ball joint, if you can see the whole stud is spinning, we're going to need to use some locking pliers at the base, to hold it. And that's loose enough. Should be able to do it with your fingers. It came out. And then pull the lower control arm, and we can pull it out.

This is our old part, this is our new part from 1Aauto.com. As you can see it comes with the nut. There is this cover that covers the boot, that's just to protect it during shipping. You want to make sure you take that off, otherwise you're going to have a very hard time getting this on. But as you can see, they look similar. They have the same studs. And there is an additional Allen. The old one has it too. If you were struggling to take the nut off like we were you can use an Allen. You will have to take the axle out to get access to this, but that would make it easier if you were in a jam like we were.

Take our ball joint and line the stud up. We're going to take our 18mm nut, get it started. Tighten it up with our 18mm wrench. If this stud ends up spinning, take notice while you're tightening it up, you can put a jack underneath the ball and push up on it, and that will put pressure on it so that it will stay locked and be easier to tighten. In this case, ours did not spin so we were good. Put the nuts on. We're going to use a torque wrench and these nuts have to be torqued.

Now we're going to install the tire. Line it up with the holes and hold it, and we'll use our 17mm socket to put our lug studs on. Or lug bolts. Whatever you want to call it. Put our center cap on. Now we're going to torque the lug studs to 120 newton meters, in a star pattern. When you do it in a star pattern it makes the wheel go flush to the brake rotor properly.

Whenever you change front end components or remove front end components and reinstall them, you always want to go to a local garage and have an alignment performed, because you are going to change the geometry of the wheel and tire going down the road, and you do not want premature wear on your tires. So you want to make sure you do that, and you'll be all set.
