Rear Suspension Link Bushing Wear
Risk: 高后悬架连杆衬套磨损
737+ real-world cases
Sourced from NHTSA complaints · Reddit · Technical Service Bulletins
Worn rear bushings allow continuous rear wheel geometry drift, which accelerates rear tire wear and degrades high-speed lane stability. In severe cases, the rear end can feel loose or unsettled on highway sweepers.
TeslaNoiseClub has catalogued 737+ cases of Rear Suspension Link Bushing Wear on Tesla Model 3/Y — the rear multi-link rubber bushings crack under combined lateral load and road salt, generating a low-frequency thud that first appears at highway speeds.
Fault Cause
Tesla's rear multi-link suspension uses multiple rubber bushings to connect the suspension links to the subframe and wheel carrier. These bushings crack and harden over time due to combined lateral load, heat cycling, and — in northern states — road salt exposure. As the bushings degrade, the link-to-subframe gap increases, producing a low-frequency thud or knock when the suspension is loaded: most noticeable when crossing speed bumps or during braking.
Symptoms
Diagnosis Steps
1. Raise the vehicle and visually inspect all rear suspension link bushings for cracking, rubber separation, or visible gaps between the rubber and metal sleeve. 2. Grip each rear wheel at the 9 and 3 o'clock positions and attempt to move it laterally — any looseness or sound indicates bushing wear. 3. Check the rear tires for single-side abnormal wear, which indicates the rear geometry has already shifted.
Confirmation Method
With the vehicle raised, use a pry bar to apply load to each rear suspension link. Any visible displacement between the bushing sleeve and the link mount, or a clunking sound under load, confirms bushing failure.

Frequently Asked Questions
Why does my Tesla Model 3 / Model Y make a 咚咚 or 咔咔声 when 过减速带 or 刹车瞬间 or 起步 or 高速?
Tesla's rear multi-link suspension uses multiple rubber bushings to connect the suspension links to the subframe and wheel carrier. These bushings crack and harden over time due to combined lateral load, heat cycling, and — in northern states — road salt exposure. As the bushings degrade, the link-to-subframe gap increases, producing a low-frequency thud or knock when the suspension is loaded: most noticeable when crossing speed bumps or during braking. Based on 737+ real-world cases in the TeslaNoiseClub database, this is one of the most commonly reported suspension noise issues on Tesla Model 3 / Model Y.
How do I know if my Tesla Rear Suspension Link Bushing Wear needs replacement?
With the vehicle raised, use a pry bar to apply load to each rear suspension link. Any visible displacement between the bushing sleeve and the link mount, or a clunking sound under load, confirms bushing failure.
Is it safe to drive my Tesla with 咚咚 or 咔咔声 from the 后轮?
Worn rear bushings allow continuous rear wheel geometry drift, which accelerates rear tire wear and degrades high-speed lane stability. In severe cases, the rear end can feel loose or unsettled on highway sweepers.
How many Tesla owners have reported this Rear Suspension Link Bushing Wear issue?
TeslaNoiseClub has recorded 737+ cases of Rear Suspension Link Bushing Wear failure across Tesla Model 3 / Model Y, sourced from NHTSA official complaints, Reddit community reports, and technical service bulletins.
Tesla Model Y rear end thudding or knocking noise over speed bumps — what is causing it?
A low-frequency thud or knock from the rear of a Tesla Model Y when crossing speed bumps or rough pavement is typically caused by worn rear suspension link bushings. The multi-link rear suspension on Model 3 and Model Y uses rubber bushings at each link mount; as these bushings crack and harden, the links develop play that produces an impact sound every time the suspension loads. This is distinct from the sharper metallic knock of a failed sway bar link and is one of the top rear suspension complaints in the TeslaNoiseClub database.
Tesla rear suspension clunking noise — is it a bushing or something else?
Rear suspension clunking on Tesla Model 3 and Model Y most commonly originates from two sources: worn rear suspension link bushings (dull thud, worse over bumps) or a failed rear sway bar link (sharp metallic knock, worse when cornering or braking). Bushings produce a duller, lower-frequency impact sound and are typically confirmed by raising the vehicle and prying each rear link. TeslaNoiseClub has documented 737+ cases of rear bushing wear across the Model 3/Y platform.
