Search button is your friend! LOL

Anyway, I have found that they are easiest through the wheel well. I typically use a jack to lift a bit so there is more of an opening in the wheel well, then hold the splash shield up while I remove the plugs. The passenger side is straight forward. The center plug (#3) on the driver's side is a bit of a pain, but I had good luck with a standard socket and my wobble extension to loosen it.

I do exactly what Kyle said, but for the drivers side I disconnect the steering arm for more rrom. Its 1 bolt. 10m i think.

I am not shure what you mean? Are you talking about the drivers side? If so is must be that the steering rod is in the way. is so use a very short extension with a swivel.

really no need to disconnect the steering arm. A swivel will do it. you can also jack up the engine just a little, with a BLOCK OF WOOD!! to give you that extra inch you need

When I replaced the plugs in my 2000 Blazer I got the passenger side from the top of the fender well with a step stool... but going through the fender well with a long extension works too. On the drivers side I used a the long extension and for the plug obstructed by the steering arm you just have to remove the plastic cover and rotate the steering shaft so that you can get a swivel socket past. And get a piece of 3/8 fuel hose, 8-10 inches will work fine, slip it over the end of the plugs. It makes putting the plugs back in a lot easier (learned this from an old mechanic), it really works, I also have a FWD V6 Grand Am and the plugs at the rear of the engine are a pita to replace using the fuel hose was a reall help since there is limited space with the rear cylinders only a few inches from the firewall...

I also do like the previous posts with one exception. To get the tight one by the steering shaft, I use a combination wrench on the end of the socket.
