You get in your Tesla, put it in drive, press the pedal — and there it is: a dull clunk or thud from the back of the car. It might happen every single time you start your drive, or when you go from reverse to drive in the driveway, or when you lift off and get back on the accelerator. If that sounds familiar, you're not alone. It's one of the most frequent noises Model 3 and Model Y owners ask our Tesla repair team about, and a very common culprit is the rubber bushings that hold the rear motor in place.
Your Tesla's rear motor — officially the rear drive unit — combines the electric motor, gearbox, and differential in one heavy assembly. It doesn't bolt rigidly to the car. Instead, it's mounted to the rear subframe using rubber bushings and a mount, which let the unit move slightly while absorbing vibration and isolating noise from the cabin. Tesla's own service procedures list a dedicated rear drive unit mount and bushing set for this exact job, covering the gearcase bushing and the left- and right-hand bushings pressed into the drive unit casting.
Those bushings do a lot of work. Every time you accelerate, the motor delivers instant torque, and the drive unit twists against its mounts. Every time you lift off or use regenerative braking, it twists the opposite way.
Rubber doesn't last forever. Even in a gas car, engine and transmission mounts are well-known wear items. Teslas make it tougher in a few ways:
Over time the rubber develops cracks, compresses, or tears away from the metal sleeve. Once that happens, the drive unit has extra room to shift, and when torque is applied it knocks into its limits instead of being cushioned. That's the clunk you hear.
Watch for these signs on your Model 3 or Model Y:
Some Tesla owners are told a clunk is normal, and sometimes minor noise really is within spec. But a repeatable clunk on every start isn't something to wave away. Left alone, worn mounts let the drive unit move more than designed, which can put extra stress on surrounding components like the half-shafts, wiring, and the mounts themselves, and it usually gets louder over time rather than going away.
It's also worth knowing that clunks can come from more than one place. Rear suspension control arms, sway bar end links, half-shaft joints, and internal drive unit wear can all produce similar-sounding noises (we cover the suspension side in our Tesla Model 3 & Model Y suspension wear guide), and on rare occasions the drive unit itself is the issue. That's why we always start with proper diagnostics before replacing parts — a thorough inspection tells you whether you need a bushing repair or something else entirely, so you're not paying for the wrong fix.
Replacing the rear drive unit bushings is a more involved job than most suspension repairs, because the drive unit has to be lowered out of the car so the old bushings can be pressed out of the casting and new ones pressed in with the correct tools. At Nexus Auto Group, our technicians:
Because the unit is already out of the car, it's also the ideal time to look over nearby wear items so you only pay for the labour once. If we spot anything in the rear suspension, we'll show you and quote it before touching it, and you can add a complete vehicle inspection for full peace of mind.
Dealer service centres can be expensive and booked out for weeks. Nexus Auto Group offers competitive pricing on Tesla rear motor bushing repair, and we'll give you a clear quote before any work begins — no surprises. Contact us for a quote on your Model 3 or Model Y. Because we diagnose first, you'll only pay for what your car actually needs.
If your Model 3 or Model Y clunks when you start your drive, don't wait for it to get worse. Bring it to Nexus Auto Group for a full inspection and an honest answer on what's causing it.
