• Test all shocks and struts for proper performance. Listen for any noises when bouncing the vehicle. Remember the vehicle may not bounce excessively during this test, but may still have weak shocks or struts because of age.
• Check air pressure in all tires including the spare. Make sure the tires are the same size. If the tires are oversized the brake performance could be compromised. Next, measure the curb ride height of the vehicle.
• The weight of the vehicle must be on the tires to ensure an accurate inspection of the steering system and an accurate ride height evaluation. Marginal inner tie rods and other steering and suspension components can be missed of this step are not followed. While the weight of the vehicle is on the tires, have a helper turn the steering wheel side-to-side, putting alternating tension and compression on each steering joint. Put your hand on each steering joint and feel for any play or popping action.
• Raise the vehicle and double check all steering components as well.
• Alignments tire wear are also factors.
