Hi, I'm Mike from 1A Auto. I hope this how-to video helps you out, and next time you need parts for your vehicle, think of 1AAuto.com. Thanks.

In this video, we're going to show you how to replace a sway bar link of this 2003 GMC Envoy XL. We show you on the passenger side, but the driver's side is a similar procedure. The items you'll need are a new sway bar link from 1AAuto.com, 7mm and 19mm socket and ratchet, 17mm and 18mm wrenches, 4.5mm Allen wrench, flat blade screwdriver, torque wrench, jack and jack stands, and depending on the condition of your vehicle, you may also need a pry bar and a reciprocating saw.

Start out by removing the wheel and tire. Pry off the hubcap. If you don't have the benefit of air tools, keep the wheel on the ground. Loosen the lug nuts first, then raise and secure the vehicle. For this repair you have to lift up both front tires evenly. Use jack stands to secure it. Then remove the lug nuts, wheel, and tire.

Start off by just lightly spraying the nut with some penetrating oil on both sides of your sway bar link. You want to make sure it doesn't get into the hole on the front of that stud because you want to make sure that the Allen wrench can stay in there. Place an 18mm wrench onto the nut and then, using a 4.5mm Allen wrench, just stick it into that stud. Then, just remove that nut. Now, you may need to clean out the inside of that stud so you can get the Allen wrench in there, on the back here. Ours was filled with dirt. We just scrape it out with a flat blade screwdriver. Then repeat the process that you had done on the lower stud.

On our vehicle we had an issue. We basically got the nut off on the top side. We got it mostly off, but then the nylon locking just locked it up and we couldn't get it out anymore. We're using a reciprocating saw to cut the stud on the sway bar link. We're using that pry bar. We're just supporting it so that the sway bar doesn't move up and down as we're using the saw. Hopefully you don't have to get to this point, but if you do this is how you can overcome not being able to get the nut off or if it's broken or frozen or anything like that.

On the right, is the old link. On the left, is the new one. You can see they are similar and they're going to fit exactly the same. Take your new sway bar link and just put the grease fittings into place. Using a 7mm socket and ratchet just tighten up those grease fittings. Push the studs on the sway bar link back into place. Then twist the nuts into place. Then just tighten up that 18mm nut and hold the inside nut with a 17mm wrench. Repeat the process with the other stud.

Replace your wheel. Replace the lug nuts and tighten them up preliminarily. Lower the vehicle, tighten them the rest of the way and torque each of them to a hundred foot pounds in a crossing pattern.
