Suspension and Shock Absorbers
Check for oil leaks and whether the rubber bushings are aging or cracked;
Refurbished parts may appear unusually shiny, have shallow grooves, and the tire sidewall may not align smoothly with the tread.
Wheels and Tires
New tires have a natural color and tread depth ≥ 1.6mm; refurbished tires have bright colors, soft sides, and rough seams.
Steering Tie Rods and Ball Joints
Hold the tie rod and shake it firmly; no shaking is normal; looseness indicates a safety hazard.
Control Arm Bushings
Check for cracks, deformation, or detachment; damage can cause drift or wobbling.
