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. We break down 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: lower ball joints — diagnosis, repair options, brands
Lower ball joints on M3/Y last longer than the upper ones, but fail by the same scenario: boot tears, grease leaks out — squeak/crunch over bumps and when turning the steering wheel. Whether to replace just the ball joint or the entire arm, and which brands to buy.
Tesla S/X/3/Y: strut top mounts — signs of failure and replacement
The strut top mount (the rubber 'pillow' with the bearing) is a common source of squeaks when turning the wheel and a dull clunk over big bumps. On M3/Y it's a simple, inexpensive unit; on S/X with air suspension it's a separate story since it's often replaced together with the strut. We cover symptoms and options on each platform.
Tesla S/X/3/Y: sway bar end links — knocking on small bumps
Sway bar end links (called 'kostochki' in chat) are a typical source of light metallic knock/rattle on small bumps, especially in winter and shoulder seasons. The approach differs between Model 3/Y and S/X. Budget aftermarket (Patron, Technorot) often last as long as Tesla OEM.
Suspension calibration in Service Mode after repair
After replacing arms or shocks, suspension calibration via Service Mode is mandatory. Without it — error on the screen.
