The front left can be changed from under the hood. The rest must be changed from under the fender. To change the middle one on the drivers side you must either use a wrench or unbold the stearing shaft and move it out of the way. I have changed pluggs on a 1994, 1999, and 2 2000 S-10 trucks and Blazers.
