Strut and Shock Replacement Planning Guide
Worn shocks or struts can affect tire contact, braking stability, ride control, and steering behavior. Inspect for leaks and damage, compare symptoms with tires and other suspension parts, replace components in the correct axle pairing when appropriate, and plan for an alignment after work that changes geometry.

Useful tools and parts
- Vehicle-specific dampers or complete struts
- Spring compressor only if the procedure requires it
- Torque wrench
- Wheel chocks
- Jack and rated stands or a lift
Planning checklist
- Confirm whether the vehicle uses a complete strut assembly or a separate spring and damper, and identify any electronic or adaptive-suspension requirements.
- Inspect tires, mounts, bushings, ball joints, links, and ride height so a damper is not blamed for a different fault.
- Use approved support and spring-compression equipment, transfer parts only when safe, and torque fasteners at the specified ride-height condition where required.
- Check ride height, steering, tire clearance, and fastener torque, then obtain an alignment whenever the work can change suspension geometry.
Safety note: Compressed springs store substantial energy. Never disassemble a strut without the correct compressor and procedure. Do not drive if steering, braking, or wheel attachment is uncertain.
Common questions
Should shocks or struts be replaced in pairs?
Replacing both sides on the same axle is commonly recommended so damping remains balanced, but follow the vehicle and component manufacturer’s guidance.
Why does the car still bounce after new struts?
Possible causes include incorrect parts, a damaged spring or mount, worn control-arm components, installation errors, tire problems, or an unresolved suspension fault.
