Vehicle Repair & Rebuild Work

Hands-on engine, timing, CVT, electrical, suspension, front-end, and return-to-road repair work across multiple salvage and high-mileage vehicles.

Problem

Salvage and high-mileage vehicles rarely have one clean failure. Mechanical damage, electrical faults, drivetrain wear, suspension work, and previous repairs interact.

Description

What I built or investigated

Independent vehicle work spanning OBD-II diagnosis, engine teardown, timing and oil-pump access, CVT disassembly, CV axles, suspension, brakes, subframes, electrical systems, collision repair, and return-to-road validation.

Iterations

The work did not happen in one jump.

01
Used scan data and symptoms to separate transmission-control issues from mechanical failure.
02
Removed front suspension, CV axle, steering, and subframe assemblies when external checks were insufficient.
03
Opened and organized CVT components—including case halves, valve body, pulley/belt assemblies, and fasteners—for inspection and comparison.
04
Performed deep front-engine teardown to access timing components and the oil-pump area rather than treating a low-pressure symptom as a simple external fault.
05
Reassembled timing and front-cover systems in stages, verifying alignment and component placement before closing the engine.
06
Completed front-end and cooling-package work in difficult outdoor conditions when shop space was unavailable.
07
Returned salvage and failed vehicles to usable condition through staged mechanical, electrical, suspension, brake, and road-test work.

Result

Where the project landed

Multiple vehicles were moved from salvage, drivetrain failure, or major disassembly toward roadworthy use. The work created practical experience across complete systems rather than isolated parts replacement.

Lessons

What carried forward

A scan code is a lead, not a diagnosis.
Access and teardown planning can determine whether a repair is economical.
Roadworthy completion requires the whole system—brakes, steering, electrical, cooling, and drivetrain—not only the failed part.
