Quick FAQ

Does a Tesla need suspension calibration after replacing control arms or shocks?
Yes. After control arms or shocks are replaced, the suspension is calibrated with Tesla software. Without calibration a Model S/X with air suspension shows an error on the screen; on a Model 3/Y a wheel alignment per the manual is mandatory after replacing arms. Some shops forget this step or don't know how to do it.
What is used to calibrate Tesla suspension?
Only Tesla software: Service Mode or Service Mode Plus, and Toolbox 3 for the air suspension ride height on S/X. Software alone is not enough: you need to understand the whole process and follow the service manual (proof). Tesla's documentation is at service.tesla.com.
Is a wheel alignment needed after replacing control arms on a Model 3/Y?
Yes, Tesla's manual makes it mandatory. The on-screen error for missing calibration only appears on S/X with air suspension, so on a 3/Y the absence of an error does not prove the job was done. On a 3/Y, Service Mode is used for the offset test drive and related routines.
What if the shop did not calibrate the suspension?
Don't take the car back with an error; demand that the work be redone. In a case from the chat a car left the shop with an error after suspension repair, and a technician put it plainly: the suspension was not calibrated, and a car with that error should not be released (proof).

Description

After suspension repair (replacing arms, shocks), calibration with Tesla software is required. An on-screen error without calibration appears only on S/X with air suspension; on 3/Y after replacing arms a wheel alignment per the manual is mandatory, while Service Mode is used for the offset test drive and related routines. Some shops forget or don't know how to do it.

Solution

  1. Calibration only with Tesla software: Service Mode / Service Mode Plus, and air suspension ride height calibration with Toolbox 3.
  2. Software alone won't cut it: you need to understand the whole process and follow the manual.
  3. If the shop didn't calibrate, don't accept the car with an error; demand it be redone.
  4. Documentation: service.tesla.com.

Model S/X: subframe bushings, clunk and hum over bumps

Rear subframe bushings on Model S/X harden and crack over time. On larger bumps a characteristic 'boom-clunk' appears; on cornering, slight rear-axle wander. Replacement is possible but labor-intensive: the subframe must be dropped. Symptoms, kit options and the real Minsk budget.

Model S/X: rear toe links and bushings, well-known weak point

On Model S and X, the rear toe links and their bushings are a typical weak point. The bushing sags, the rear wheels go 'house-shape' (negative camber), tires get chewed from inside. What to choose: a new arm assembly, refurb with bushing rebuild or adjustable links, and how much it costs in Belarus.

Model 3/Y: front creak/crunch when steering or over bumps, upper control arm (ball joint)

The classic 'old cart' creak at low speed and during steering changes. Most often the front upper control arm is at fault (the ball joint in the 'horseshoe'): grease leaks out, the ball goes dry, and a creak appears. What to do as a temporary fix (syringe/grease) and how to solve it properly (replace with the updated arm).
