Prechecks

2. Raise front of vehicle off floor. Grasping upper and lower surfaces of tire, move each front wheel in and out to check front suspension ball joints and mounts for looseness, wear and damage. Tighten all loose nuts and bolts to specification. Replace all worn parts.
3. Check steering gear mountings and tie rod connections for looseness. Tighten all mountings to specification. If tie rods are worn or bent, replace parts.
4. Spin each front wheel with wheel spinner and check and balance each wheel as necessary.
5. Check action of shock absorbers and suspension springs. If they are not in good condition, vehicle may not settle in normal/level position.
