Sway bar link replacement.

03 Envoy.

Just finished replacing the back, and what a PITA. Passenger side took 30 minutes, no prob. The driver side took about 4 hours, 3 bloody knuckles and 2 sawzaw blades. Took it for a test ride, and well worth it.

I Thought that if the back were easy, I would try and take on the front. I am looking for some input about the front from someone who has replaced all 4. Is the front easier??

I just did all four today (02 envoy). It's a lot easier with the wheels off. I was rotating the tires anyway, so I just put it up on jackstands with all the wheels off and the suspension unloaded.

For me, the fronts were about the same as the rears. I felt like an idiot because it took me a while to realize that there's an allen socket in the end-link bolts. After breaking the nuts loose, I just kept a 18mm end-wrench on the nuts and used an allen socket to turn the bolts out of the nuts (sounds backwards, but it worked well). I had a 1/2-inch drive on the allen socket which really helped unthreading the nut over the rust.

Once I got them far enough off, I just put a pair of vice-grips on the back of the stud and finished taking the nut off with a normal 18mm socket.

Hope that helps!

I had to do the same to my left front when I replaced all four. Damn thing was a pita to get off. Just have fun and keep thinking of the ride to come and the way it should have been.

when I replaced my links I cheated and ran a thread chaser over the exposed threads that were rusted up and the nuts cam right off!. I was also using a 3/8 impact gun on a hoist too.

Fronts are easier than the one at the gas tank in the rear. You have to be patient and take what the wrench will give you in terms of percentage of a full turn. I think about an 1/8 of a turn is all you can get on the driver's rear. A box end wrench and an allen 'socket' will help. Make sure the allen gets fully seated.
All's well that ends well!

Question about end links

Will replacing the end-links have any performance difference other than sound? I have 90K on my 02 TB and know they are shot, but I don't get an annoying noise....atleast anymore. My front end has recently started to "wander" when I accelerate through a turn and I'm not sure if replacing these would help or if it is soley because my shocks/tires are worn. My HD bilsteins are arriving this week for the front, rears already installed. Thanks for the help!

I think the feeling up front felt more solid and tighter after having mine replaced. Every now and then my passenger side seems to loosen at the upper mount, and the truck feels like its wandering when it does....crawl under and tighten the damn thing and she feels tight again. - So I'd say that the end-links DO contribute the way the truck feels and handles.

I had the same problem with my drivers side rear. I had to use a sawzaw and cut it off. To replace all four, it took me like 4 hours.

I deleted your duplicate post in another forum. Once is enough at trailvoy.

It's safe to drive with worn links. It's even safe to drive with NO links. Just not at high speed on twisty mountain roads. You'll know what's safe by the increased amount of lean you'll get.

It's just noisy.

Tie rod ends and ball joints are another matter. They are primary suspension system elements. The anti-sway bar is just an add-on.
