Chassis Dynamics & Pothole Repair

SUSPENSION & STEERING.
ROCK-SOLID HANDLING & STABILITY.

Quebec potholes bend control arms, crack coil springs, and throw off wheel alignment. We rebuild suspension geometry with heavy-duty components and laser 4-wheel alignment.

Pothole Damage Diagnosis

RESTORING CHASSIS GEOMETRY & WHEEL TRACKING

Hitting a deep winter pothole exerts thousands of pounds of impact force directly into suspension uprights, lower control arms, sway bar links, and steering knuckles.

Heavy-Duty Control Arms & Ball Joints

Premium greasable ball joints and forged aluminum or stamped steel control arms built to withstand rough roads.

Coil Spring & Strut Assembly

Replacing fractured coil springs and leaking gas-charged dampers to eliminate chassis roll and nose-dive.

Inner & Outer Tie Rod Replacement

Restores crisp zero-play steering response and prevents high-speed tire wandering.

RESTORING CHASSIS GEOMETRY & WHEEL TRACKING

Inspecting lower control arm polyurethane bushings and ball joint play.

Laser 4-Wheel Alignment

CAMBER, CASTER & TOE-IN PRECISION

Even 1 degree of toe misalignment will scrub tires bald in less than 5,000 km while increasing fuel consumption.

Thrust Angle Verification

Ensures front and rear axle centerlines align squarely with vehicle chassis center.

Steering Angle Sensor (SAS) Reset

Calibrates electronic power steering sensors so traction control and lane-keep assist operate accurately.

Tire Life Maximization

Eliminates inside edge feathering and cupping wear on expensive seasonal tires.

CAMBER, CASTER & TOE-IN PRECISION

Computerized laser alignment heads measuring camber, caster, and thrust angle.

Diagnostic Phases

THE CHASSIS INSPECTION WORKFLOW

We put your vehicle on hydraulic shake tables to diagnose elusive suspension clunks and creaks under real load.

1. Acoustic Shaker Table Diagnosis

Simulates road bumps to pinpoint worn stabilizer links and dry ball joint sockets.

2. Subframe Bushing Pressing

Hydraulic pressing of high-density rubber bushings without damaging aluminum knuckles.

3. Steering Rack & EPS Inspection

Checking hydraulic fluid lines, electronic power steering motors, and universal steering column joints.

4. Printed Alignment Spec Sheet

Before-and-after color printout showing exact camber, caster, and toe specifications.

THE CHASSIS INSPECTION WORKFLOW

Completed suspension overhaul tested on digital alignment rack.

Q&A

Frequently Asked Questions

Clear answers regarding auto collision, insurance claims, paint matching, and warranties in Quebec.

01. What are the warning signs of failing suspension components?

Common symptoms include clunking sounds over bumps, excessive bouncing after dips, vehicle pulling to one side, uneven tire cupping wear, and a loose steering wheel feel.

02. Do I need an alignment after replacing suspension parts?

Yes, absolutely. Replacing struts, control arms, ball joints, or tie rods alters suspension geometry. A computerized 4-wheel alignment is essential to ensure straight tracking and prevent tire wear.

03. Can hitting a pothole bend a car's subframe?

Yes. Severe pothole impacts can bend engine cradles and lower control arm mounting brackets. We inspect subframes for distortion and realign them to factory specs.

04. How long does a suspension overhaul take?

Most strut replacements, control arm installations, and 4-wheel alignments are completed in 3 to 6 hours on the same business day.
