How do I fix my noisy blender that's shaking too much

I got this blender a few months ago for making smoothies every morning. It started making loud noises and shaking a lot lately. I can't afford a new one right now because money is tight. I tried cleaning it but that didn't help. Maybe something is loose inside. I looked online but the fixes seem hard. What easy steps can I try at home? I just want it to work smooth again.

I had the same thing happen with my morning smoothie blender. Mine got loud and started walking on the counter after a few months. Cleaning alone did not help. What worked first was moving it to a solid surface and making sure all the rubber feet were there and level. I checked the jar was fully seated, then reloaded with liquid first, soft fruit next, frozen last, and used a few short pulses before a steady speed. The real fix was under the jar. I unscrewed the blade base, cleaned the threads, laid the rubber gasket flat and even, then tightened the base hand tight using a dish glove for grip. That stopped most of the shaking.

The last bit of noise was a worn drive coupler with rounded teeth. I unplugged the blender, pried off the old coupler, and spun on a new one that cost a few dollars. Ten minutes and it was smooth again. If those steps still do not tame it and you need a cheap fallback, I switched to Hamilton Beach blender and it stayed stable thanks to a 700 watt motor and a heavier glass jar.

Mine got loud & jumpy after a few months too. The easiest wins for me were about setup and loading. Put it on the flattest and heaviest part of the counter and make sure all four feet touch at the same time. Seat the jar with a firm twist until it stops. Pull the blade base once more, check the rubber ring is flat with no twists, and thread the base back on straight. Hand tight only. On the recipe side pour liquid first, then soft stuff, then hard or frozen on top. Start on low for five to ten seconds, give two or three quick pulses, then step up. Smaller batches help more than you think. If the blender starts to cavitate or rattle, stop and swirl the jar off the base to move the heavy bits, then resume. Unplug before removing or handling the blade assembly. These small changes tamed the noise for me. Works great.

Another quick stabilizer is a silicone trivet or even a damp dish towel under the base to absorb vibration and stop the “walking.” With the jar off and the blender unplugged spin the blade hub by hand; if it feels gritty or wobbles side to side and the blade assembly bearing is wearing out, and replacing that part is usually cheap and cures the shake. Also let frozen fruit sit a few minutes or chop big pieces smaller so the first seconds on low don’t pound the motor.

Yeah, i feel you on the blender woes, especially when cash is short and you rely on it daily. My old one started doing the same – loud as heck and dancing around. Cleaning didn't cut it for me either, so I dove a bit deeper without any fancy tools.

I unplugged it first for safety, then flipped it over to inspect the bottom. Turned out the feet were worn uneven, so I stuck some felt pads under the wobbly ones to level it out and that helped with the shaking, but the noise persisted so I looked at the blade assembly and yeah, it was gunked up inside even after surface cleaning, so I disassembled it carefully, washed everything thoroughly, and put it back together snugly, and it ran much quieter after that.

Blenders can be finicky like that after a few months of heavy use so yeah i've fixed a couple over the years by tackling the common culprits step by step. Start by ensuring the jar is locked in properly; sometimes it's not fully engaged & causing vibrations.

Next, examine the blade area. If you can remove it, do so and clean out any built-up residue that might be throwing it off balance. Reassemble firmly. For the shaking, try placing a damp towel under the base to absorb some of the movement.

If it's still noisy,, the issue might be with the bearings or coupler, but that's trickier. I once had to lubricate the moving parts lightly with food-grade oil. a tiny bit. Fixed it right up. And don't forget to pulse instead of going full speed right away – eases the strain.

Before opening anything & try load and speed which, yeah overfilled jars hammer the motor and make the whole thing dance. Leave some headroom, add a touch more liquid, put frozen stuff on top, and cut hard pieces smaller. Start low, give a few short pulses, then step up. If it starts chattering, stop, lift the jar off, give it a quick swirl to redistribute, and resume.

One more easy tweak is jar orientation. Some bases have several lock positions and one may run smoother than the others. Rotate and try each spot to see which is quietest and stick with that.

Good point - Besides load and speed check the simple mechanics. Flip the jar over and hand‑snug the blade assembly/collar and making sure the rubber gasket sits flat and isn’t nicked; a loose collar or bad gasket makes them rattle. Inspect the drive coupler on the base and the gear under the jar - wobbly or chewed teeth cause shaking; if it’s loose, tighten or swap the coupler. Setting the blender on a damp towel or silicone mat and ensuring all feet touch a level surface will also tame vibration.

Hmm, I fixed a shaky one in a shared kitchen without buying parts... No tools. First I washed and dried the threads where the jar meets the blade base, then reseated the rubber ring so it lay flat and even. If it is cross threaded the blade sits crooked which screams and vibrates. I tightened by hand, backed off a touch, then tightened again to be sure it was square. Next I moved it to the sturdiest corner of the counter and made sure the cord had slack so it was not tugging the base. Starting on low while holding the lid with one hand and resting the other hand lightly on the jar steadied the first second, then I let it run on its own. That stopped the walking and cut the noise a lot.

Good add. Also check the base sits flat - if a rubber foot is missing or uneven shim it or set the blender on a damp dish towel to soak up vibration. Load order matters: liquid first, then soft stuff, hardest or frozen on top, and pulse on low before ramping up. Unplug and gently check for side play in the blade; if the gasket is nicked try flipping or reseating it, and if the blade still wobbles keep blends short and skip ice so it doesn’t get worse.

Tech angle. honestly Take the jar off and unplug the unit and and look at the drive piece on top of the base. If the teeth are rounded or the piece wobbles side to side, that can make a racket. Check the blade assembly too by spinning it carefully with the jar off the base. It should feel smooth and not gritty and it should not rock up and down.

If either part has noticeable play, blend lighter loads, add a little more liquid, and run in shorter bursts to reduce stress. That buys time. I also found a couple of loose screws underneath that tightened the motor mounts and cut most of the shaking. Unplug first, keep fingers clear of sharp edges, and do not run it open.

Quick note - Along with checking the coupler and blade play pull the jar apart and make sure the blade base is screwed on snug with the rubber gasket seated flat; a loose base or hardened gasket can make it wobble and howl. Make sure the rubber feet are intact and put the blender on a silicone mat or folded towel to soak up vibration. If the small rubber drive coupler on the base is chewed up, replacements are cheap and usually twist off/on without opening the unit.

Set it on a flat and stable surface and tighten the base to reduce vibration. Blend smaller batches and give the motor short breaks to prevent rattling and overheating.
