I have a 1998 blazer, and the steering seems to be off. When you move the wheel to the left and to the right it doesn't register right away, you actually need to move it quite a bit. It doesn't seem lose so I'm not sure what's going on

 

You have worn steering components. If you are able to safely lift your vehicle and support it on stands you can have a friend turn the wheel while you look for obvious problems with the linkage. If you are not comfortable crawling under your vehicle or do not have a safe way to support it then take it to a shop.

 

Sounds about right ill have to check it out, I'm not a car guy but I am definatly going to check it out.

 

Always check steering components in a loaded, as driven condition. This is referred to as a "dry park" inspection. With the vehicle on the ground have a friend work the steering wheel back and forth quickly while you observe by sight and feel for any components not traveling together. Start at the outer tie rod ends and steering arms and work your way across. Inner tie rods, pitman arm, idler arm(some idlers may have play 0.030" is normal). Also check for play in steering shaft and gear box. Look for loose fasteners where the gear box bolts to the frame. Swaybar bushings and endlinks. All joints should rotate with hand pressure (50lbs.) do not use tools(prybars).
Check wheel bearings and balljoints with the vehicle lifted by the lower control arms.

 

Tie rod ends should rotate a little, but nothing should "wiggle" at all.

With it on the ground, have someone push it side to side a little while you climb under, and look for anything moving. Once found loose idle arm bolts to the frame in under 30 seconds.

Then with one wheel in the air, jacked from the control arm, push the wheel the way it turns (front and back sides) - it should not move. If it does, look for what moves. Check the other side too.

Have someone move the steering wheel with a constant back and forth, check if pitman arm follows. If the arm seems to stop when changing directions, and the steering wheel isn't, the slop is in or above the steering box. It helps to have both front wheels up for this, when down the tires can "spring" the arm back.
