2. Check front wheel bearings, suspension arm bearing, ball joints and track rods for damage, replace components as necessary.
3. Check rack and pinion steering gear and adjust as necessary.
4. Check shock absorbers for damage, replace as necessary.
5. Rock vehicle backward and forward, then bounce it upward and downward to settle vehicle prior to alignment.
