Courses
Seven courses on the app's 3D models of real car systems, from the engine to the brakes. Each starts with five short lessons, then gives you two workshop jobs, such as a brake pad change or a clutch kit, where you pick every part, tool and torque. The courses come with Full Garage, the app's one-time unlock.
How a course works
Five short lessons on the 3D model, each a few cards long. The model comes apart and runs as you read, and every lesson ends with a quick check: tap the right part or pick the right answer.
Each job runs in workshop order. The part to work on glows, and the app shows the step, the tool and the torque.
Then do the job on your own: pick the next part, the tool, its size and the torque. Wrong picks and hints cost stars, and three stars means a clean job.
Each job opens with its safety notes. The torques are typical values for the app's model: on your own car, follow its service manual.
Seven courses
Suspension
How the strut carries, damps and steers the wheel, and the jobs that keep it right.
5 lessons
2 jobs
Replace a sway bar link
Swap a worn sway bar link for a new one: the classic first suspension job.
Replace a tie-rod end
Swap a worn tie-rod end, keep the alignment close, then have it checked.
Wishbone
How two control arms keep the tire flat on the road, how the coilover carries the car, and how to change a control arm.
5 lessons
2 jobs
Replace an upper control arm
Swap a worn upper control arm: split its ball joint, take out the pivot bolts, slide it out past the coilover, and tighten the new one at ride height.
Replace a lower control arm
Swap a worn lower control arm: free the sway bar link, let the suspension hang so the shock's fork comes free, split the ball joint, drop the arm out, and tighten the new one at ride height.
Brakes
How a rotor brake stops the car, how it wears, and how to change pads and bleed the brakes.
5 lessons
2 jobs
Change the front pads
Fit new front pads: swing the caliper up, swap the pads, push the piston back and refit.
Bleed the front brakes
Push fresh fluid through the caliper until no air comes out. On a full bleed, start at the wheel furthest from the master cylinder.
Steering
How the wheel turns the road wheels, how the assist helps, and the jobs on the inner tie rods.
5 lessons
2 jobs
Replace a rack boot
Fit a new boot before grit gets into the rack: the tie-rod end comes off, the old boot slides off the rod, the new one goes on, and everything goes back to its marks.
Replace an inner tie rod
Swap a worn inner tie rod: the tie-rod end and the boot come off, the old rod unscrews from the rack, and the new one goes on at the old one's length.
Drivetrain
How the CV joints and the differential get the power to the wheels, and how to fit a boot or a whole half-shaft.
5 lessons
2 jobs
Replace an outer CV boot
Fit a new boot to the outer joint before grit ruins it: the joint comes off the shaft, gets fresh grease, and goes back with new clamps.
Replace a half-shaft
Swap the whole half-shaft, joints and all: out of the hub, levered out of the transmission, and the new one clicked back in.
Engine
How four strokes, the valves, the oil and the spark make an engine run, and the two services every owner can do.
5 lessons
2 jobs
Change the oil and filter
The service that matters most: drain the old oil warm, fit a new filter and a new washer on the plug, fill up and check the level.
Change the spark plugs
Fresh plugs for a smooth idle and a clean burn: the coils come out, the plugs come out one at a time, and each new one goes in to its torque.
Clutch
How the clutch clamps, lets go and bites, and how to bleed it or fit a new kit.
5 lessons
2 jobs
Bleed the clutch
Push fresh fluid through to the slave cylinder until no air comes out, for a firm pedal and a clean bite point.
Replace the clutch kit
Fit a new clutch kit (disc, pressure plate and release bearing) and a new slave cylinder. The job starts with the transmission ready to come out.
What you need
3D Mechanic for iPhone and iPad.
No. The courses teach how each system works and walk you through 14 common jobs on the app's 3D models, but they are not accredited by ASE or any other body. A career as a technician starts with an accredited program or an apprenticeship.
The jobs follow the real order of work, so you know the steps, the tools and what to check. They are a training simulation with typical values for the app's model: on your own car, follow its service manual for the procedure and the torques, and never work under a car held only by a jack.
No. Every job happens on the 3D model, and you pick each tool from a tray in the app.
Full Garage, the app's one-time unlock. It opens every system and every course. If you already own Full Garage, update the app and the courses are there.
Anyone who wants to learn the order of work before touching a real car: beginners doing their own maintenance, students and apprentices, and drivers who want to know what a job involves before they pay for it.
