Do I need an alignment after replacing struts?

Yes, absolutely. Replacing struts changes suspension geometry, and even a small change means the wheels are pointing in a slightly different direction. Skipping the alignment results in rapid tire wear and the car pulling to one side. Budget $80–$120 for an alignment when pricing the job.

What is the difference between a quick-strut and replacing the strut insert?

A quick-strut (complete assembly) comes pre-built with the spring and mount — bolt it on and you're done. A strut insert replaces only the damper inside the existing spring and mount, which requires a spring compressor tool. Quick-struts cost more but save time and tool rental.

Can I replace just one strut, or do I need to do both?

Always replace struts in pairs (both fronts or both rears). A new strut on one side and a worn strut on the other creates uneven handling — the car will lean and pull. The few dollars saved by doing only one side creates a worse problem.

How long do struts last?

Most struts last 50,000–100,000 miles. Signs of failure include excessive bounce, nose-dive under braking, the car sitting lower on one corner, oil streaks on the strut body, and knocking from the top mount area.

What it does

A strut is a combo part — it's a shock absorber AND a structural suspension member rolled into one. Unlike a standalone shock, the strut actually supports the weight of the car and is the pivot point for steering on most front-wheel-drive cars. The 'strut assembly' (also called a quick-strut) is the whole unit: the strut body, spring, and top mount pre-assembled. When a strut wears out, the hydraulic damping inside breaks down — the car bounces excessively, nose-dives when braking, and often develops a clunking or knocking sound from the worn top mount bearing.
