Spring Suspension Inspection: Ride Control Red Flags
Winter potholes, salt and temperature swings take a toll on suspension parts, even when the vehicle still feels normal to the driver. Here’s a technician’s guide to spotting ride control red flags in spring, before summer miles turn wear into a roadside problem.
Ride Control Red Flags
Winter rarely treats a suspension gently. Months of potholes, broken pavement, road salt, moisture and temperature swings can leave behind wear that is easy for a driver to miss but important for a technician to catch. By spring, a vehicle may still feel “normal” to the customer even though shocks, struts, bushings, ball joints, tie rod ends and other undercar components have taken a season of abuse.
That makes spring an ideal time for a deeper ride control inspection, especially before customers begin piling on miles during summer travel.
Start With the Evidence
Begin with what the vehicle is already telling you. On the road, pay attention to excess body movement, poor recovery after bumps, steering looseness, noise, vibration and changes in handling. In the bay, inspect the tires before touching anything else. Uneven wear or cupping can point toward degraded shock or strut performance, while irregular wear patterns may also indicate alignment or steering concerns.
A bounce test can provide an initial assessment of shock and strut condition, but it should not be the only check. Some active or adaptive suspension systems can behave differently depending on operating conditions, so manufacturer procedures should be followed where applicable.
Next, compare ride height from side to side. A noticeable difference can indicate a weakened or broken spring. Inspect shocks and struts for oil leakage, damaged housings, bent rods, deteriorated dust boots and worn bump stops. Coil springs deserve close attention for cracks or breaks, and spring perches should be checked for corrosion. On strut assemblies, make sure drainage areas are clear of packed dirt and debris that can hold moisture against the metal.
Look Beyond the Shock and Strut
Winter damage is rarely limited to one component. Pothole impacts travel through the wheel and tire into the steering and suspension, placing repeated loads on ball joints, tie rod ends, control arms, bushings and wheel bearings. Salt, water and road chemicals add another threat by attacking metal surfaces, rubber components and protective boots.
Inspect ball joints and tie rod ends for excessive play and torn or leaking boots. Check control arm and stabilizer bar bushings for deterioration, looseness or movement. Turn the steering through its range and listen or feel for binding, popping or resistance that could indicate a worn strut mount or bearing.
Wheel bearings should be checked for play, roughness or noise. Steering knuckles should be inspected for visible damage, particularly around tapered joint mounting points. CV joints and drive axles also belong in the inspection. Look closely for split boots, grease leakage or other signs that contaminants may have entered the joint.
Make the Corner Check Routine
This is where GSP’s comprehensive corner check becomes especially valuable. Rather than evaluating a shock, strut or steering component in isolation, the corner check looks at the system as a whole: shocks and struts, control arms, steering knuckles, ball joints, tie rods, wheel bearings and CV drive axles.
That system-level view matters because these components work together to maintain tire contact, alignment, handling, braking and traction control performance. Replacing one worn part without identifying another problem nearby can leave the vehicle with incomplete ride control and may compromise the quality of the repair.
Finish the inspection with a close look at tire wear and alignment condition. Winter road damage and normal component wear can alter alignment even when the driver has not noticed a pull or other obvious symptom.
Prepare Customers for Summer Miles
Spring inspection season is an opportunity to correct winter damage before it becomes a summer roadside problem. When worn components are identified, complete the necessary repairs using quality parts and follow proper alignment procedures afterward.
A thorough corner check, accurate diagnosis and complete repair help restore the handling, ride quality and dependability your customer expects. For the technician, it is a chance to solve developing problems before they become comebacks. For the customer, it means greater confidence that the vehicle is ready for daily driving, vacation travel and the long miles of summer ahead.
