Check a shock or strut replacement quote

What the job usually involves.

A strut is a shock absorber built into a structural unit that helps locate the wheel and, in many designs, carries the coil spring. A plain shock absorber only damps the motion of the spring. Many cars have struts at the front and shocks or struts at the rear.

Replacing a strut usually means removing the wheel and the strut, either fitting a complete assembly or compressing the spring with a spring compressor to move it onto the new strut, then refitting and often aligning the wheels. Shock and strut bolts that pass through rubber bushings are usually tightened with the vehicle at ride height, and the job ends with a road test.

Air suspension and some adaptive damper systems work differently. Some need a scan-tool ride-height or calibration step after parts are replaced, and the quote should list it.

What a complete written quote should state.

• The corners or axles covered, and whether the price is per corner or per axle.
• Complete assemblies or bare struts, with brand or part number.
• Which mounts, bearings, boots and bump stops are new and which are reused.
• Any spring replacement, and why.
• Whether a wheel alignment is included.
• Labor as hours or a flat price, shop supplies, disposal fees and tax.
• The written warranty on parts and labor.

What changes the total.

Scope usually matters most: one axle or both, complete assemblies or bare struts, and whether mounts and alignment are included. A quote for complete assemblies can look higher on parts and lower on labor than a bare-strut quote.

The vehicle matters as well. Electronic dampers, air suspension and heavy-duty pickup components are different parts. Part grade, the local labor rate and tax account for the rest.

Complete assembly or bare strut?

A complete assembly, sometimes called a loaded or quick strut, comes with a new spring, mount and boot already fitted. A bare strut is only the damper, so the shop compresses the old spring and moves it and the mount across. Compressing a coil spring needs the right equipment, which is one reason some shops prefer complete assemblies.

Neither option is automatically better. Ask which one the quote assumes, whether the reused parts were inspected, and compare quotes that make the same choice.

When a second opinion is worth it.

• All four corners are recommended without a written finding for each one.
• One quote covers a single corner and the other covers an axle pair.
• The quote does not say whether springs and mounts are new or reused.
• Alignment is missing from one quote and included in the other.

Worn or broken suspension parts can affect steering, braking and tire contact with the road. If a spring is broken, the car leans or the steering feels loose, have it inspected promptly rather than driving far to compare quotes.
