Key Responsibilities

Muffler and Exhaust System Repairs

• Diagnose and repair issues across the full exhaust system, including mufflers, catalytic converters, exhaust pipes, manifolds, resonators, hangers, and oxygen sensors.
• Perform precise welding, cutting, bending, and custom fabrication to replace or modify exhaust components (including custom performance setups).
• Conduct thorough inspections for leaks, corrosion, damage, rattles, and compliance with emissions standards.
• Install aftermarket, OEM, or performance exhaust systems per customer specifications.

Brake Systems (Disc and Drum)

• Diagnose, service, and repair complete hydraulic brake systems, including disc brakes (calipers, pistons, pads, rotors/discs) and drum brakes (wheel cylinders, brake shoes, hardware, springs, adjusters, backing plates, and drums).
• Inspect, replace rotors/discs; machine or replace drums as needed for optimal friction surface and performance.
• Perform full brake jobs: replace pads/shoes, hardware, and related components; clean, lubricate, and adjust for proper contact, pedal feel, and even braking.
• Diagnose and repair hydraulic components, including master cylinder (bleeding, bench bleeding, replacement for leaks or internal bypass), brake booster (vacuum/power assist testing and replacement), brake lines (steel/rigid), flexible hoses (for cracks, swelling, or leaks), and proportioning/combination valves.
• Identify and correct issues such as brake fade, pulling, noise, spongy pedal, uneven wear, drag, or ABS/traction control-related problems.
• Flush and replace brake fluid; bleed the system to remove air and restore firm pedal response.
• Ensure compliance with safety standards and perform test drives to verify proper braking efficiency and feel.

Engine and Transmission Mounts

• Diagnose worn, cracked, collapsed, or broken engine mounts, transmission mounts, and torque strut mounts through visual inspection, pry-bar testing, and symptom evaluation (e.g., excessive vibration, clunking during shifts/acceleration, engine movement, or misalignment).
• Safely support and lift the engine/transmission using hoists, jacks, or support bars to remove and replace mounts.
• Inspect and replace related hardware such as mount bolts, heat shields, insulators, and brackets.
• Perform alignment checks and adjustments post-replacement to ensure proper driveline angles and prevent premature wear on CV joints, axles, or exhaust components.
• Test-drive vehicles to confirm elimination of vibrations, improved ride quality, and proper powertrain behavior.

Wheel Bearings

• Inspect, diagnose, and replace front/rear wheel bearings and hubs to restore smooth, quiet, and safe operation.
• Use bearing presses, pullers, and specialized tools to ensure proper seating, preload, and alignment.
• Identify early failure signs (e.g., grinding, humming, wheel play) and prevent related damage.

Tie Rods and Steering Components

• Inspect and replace inner/outer tie rods, adjusting sleeves, and related steering linkage to maintain precise alignment and control.
• Diagnose symptoms like steering vibration, wander, or uneven tire wear and recommend necessary repairs or alignments.
• Collaborate with alignment specialists to achieve factory or performance specs.

Shocks, Struts, and Suspension

• Diagnose and replace worn shocks, struts, strut mounts, cartridges, and related components to enhance ride quality, handling, and stability.
• Inspect mounting hardware, bushings, springs, and other suspension parts for wear or damage.
• Perform post-repair test drives to verify proper function and customer satisfaction.

Additional Undercarriage Components

• Ball Joints: Inspect, diagnose, and replace upper/lower ball joints to preserve suspension integrity and steering precision.
• Control Arms: Diagnose and replace damaged or worn control arms, bushings, and shafts for proper alignment and ride.
• CV Joints and Axles: Inspect, repair, or replace CV joints, boots, and drive axles to eliminate clicking, vibrations, or driveline issues.
• Sway Bars and Links: Replace sway bar links, bushings, or bars to reduce body roll and improve cornering stability.
• Perform complete undercarriage inspections to proactively identify emerging issues and recommend preventive maintenance.

General Duties

• Utilize diagnostic tools (e.g., OBD-II scanners, smoke machines, listening devices) to accurately pinpoint exhaust and undercarriage problems.
• Maintain a clean, safe, and organized work area while adhering to all shop safety protocols and environmental regulations.
• Communicate clearly and professionally with service writers, leads, and customers about repair needs, findings, timelines, and recommendations.
• Stay current with industry advancements, new tools, repair techniques, and regulations through ongoing training and certifications (strongly preferred).
• Perform other related duties and shop tasks as assigned to support team success.

Note: This list covers the primary responsibilities but is not exhaustive. Day-to-day tasks may vary based on shop needs, customer demands, and seasonal workloads.

Qualifications

• High school diploma or equivalent required; vocational/technical training in automotive repair preferred.
• Minimum 3+ years of hands-on experience as an automotive technician, with proven focus on exhaust systems and undercarriage/suspension/powertrain mount repairs.
• Strong expertise in diagnosing and repairing the components listed above.
• Proficiency in welding (MIG), exhaust fabrication, and use of shop tools/equipment (including engine/transmission support tools).
• Familiarity with diagnostic equipment, hand/power tools, lifts, and alignment tools.
• Valid driver's license with clean record and ability to safely test-drive vehicles.
• Excellent problem-solving, attention to detail, and time-management skills.
• Strong communication and customer service abilities.
• Ability to work independently or collaboratively in a fast-paced environment.
• ASE certifications (especially A4 Suspension & Steering, A5 Brakes, X1 Exhaust Systems, or Undercar Specialist designation) are highly preferred and may lead to higher compensation.

Physical Requirements

• Ability to lift up to 50 lbs regularly and work in confined spaces under vehicles.
• Comfortable with prolonged standing, bending, kneeling, and working in various positions.
• Tolerance for exposure to noise, automotive fumes, fluids, and chemicals (with proper PPE and ventilation).

Work Environment & Benefits

• Full-time position (typically 40 hours/week), with potential for overtime.
• Shop-based environment with exposure to typical automotive hazards.
• Opportunities for professional growth, additional training, and advancement into lead or specialized roles.
• Competitive hourly wage based on experience, skills, and certifications.
