Short answer: a washer shaking violently in spin is almost always one of three free fixes — an unbalanced load, unlevel feet, or shipping bolts that were never removed — or, on machines a few years old, worn shock absorbers or suspension rods that can no longer damp the drum. Stop the cycle, redistribute the laundry, and check the machine with a level before assuming the worst.
Here's the full list, in the order we check it on a service call.
Is it the load or the machine?
This is the first question we ask, and you can answer it in one test. Run an empty spin cycle, or a small balanced load of similar-weight items (a few towels). If the machine spins smoothly empty but shakes with laundry in it, the problem is how the drum is being loaded. If it shakes even when empty or with a balanced load, the machine itself has a problem — keep reading.
1. Unbalanced load
One comforter, one bath mat, one pair of soaked jeans wadded up on one side of the drum — that's all it takes. The drum spins at several hundred RPM, and a lump of wet fabric on one side turns the whole thing into an off-center flywheel. Modern washers try to redistribute or slow down (Samsung shows UE, LG shows UE/UB), but older or simpler machines just shake.
The fix is free: stop the cycle, untangle and spread the load evenly around the drum, and restart. Wash bulky single items with a couple of towels for company so the weight can balance out. If you're seeing balance error codes constantly, our Samsung washer error codes guide covers what persistent UE means.
2. Shipping bolts still installed (new machines)
If the washer is new — or new to you — check this before anything else. Front-load washers ship with three or four heavy transport bolts through the back panel that lock the drum rigid so it survives the truck ride. Delivery crews are supposed to remove them. They don't always.
A washer running with shipping bolts in shakes ferociously on every load, because the drum can't float on its suspension at all. The longer it runs that way, the more damage it does. Look at the back panel for large bolts with plastic spacers (the manual shows exactly where), remove them, and keep them in a bag taped to the back for your next move.
3. Unlevel or loose leveling feet
Put a spirit level on top of the cabinet, front-to-back and side-to-side. Then grab opposite corners and try to rock the machine. If it rocks at all, a foot isn't carrying weight — and a washer that rocks at rest will walk across the floor in spin.
Each corner has a threaded foot with a lock nut. Screw the feet in or out until the machine sits dead level and doesn't rock, then tighten the lock nuts so vibration can't back the feet out again (that lock nut step is the one everyone skips, and it's why the problem comes back). On a springy or uneven floor — common in older houses around here — a piece of 3/4" plywood under the machine stiffens things up noticeably. Anti-vibration pads under the feet help on hard floors too.
4. Overloading
Stuffing the drum past capacity does two things: it prevents the load from ever distributing evenly, and it hammers the suspension on every cycle. If the shaking only happens on your biggest loads, that's your answer. As a rule of thumb, you should be able to fit a flat hand on top of the laundry in the drum. Chronic overloading is also how suspension parts get worn out early — which brings us to the actual repairs.
5. Worn shock absorbers or suspension rods
This is the most common mechanical cause we find. Front-loaders use shock absorbers (struts) between the outer tub and the frame; top-loaders hang the tub on suspension rods with dampers. Both wear out — the damping material degrades, and the tub starts swinging further and further before anything slows it down.
The telltale signs: the shaking got worse gradually over months, it happens even with well-balanced loads, and on a front-loader you can sometimes hear the tub banging against the cabinet on spin-up. A quick check on a front-loader: open the door, push down hard on the drum, and let go. It should settle almost immediately. If it bounces several times, the shocks are done.
Shocks and suspension rods are replaced as a set, and it's a routine repair — but it means tipping or partially disassembling the machine, so it's one we'd put on the technician side of the line.
6. Failed drum bearing
The worst-case answer. The main bearing supports the drum shaft, and when it fails the drum develops play — grab the inner drum and lift; if it clunks or moves noticeably relative to the outer tub, the bearing is going. A failing bearing usually announces itself with a loud rumble or roar during spin that's been getting louder for weeks, often after a slow seal leak let water into the bearing.
Bearing replacement means splitting the outer tub — hours of labor, and on some models the tub is a sealed assembly that has to be replaced whole. On a machine past eight or so years old, this is frequently the repair that doesn't pencil out. Our how old is my appliance guide helps you date the machine from its serial number before you decide.
What's safe to DIY and what isn't
| Cause | How to spot it | DIY-safe? |
|---|---|---|
| Unbalanced load | Shakes on some loads, fine on others | ✅ Yes — redistribute |
| Shipping bolts left in | New machine, violent on every load | ✅ Yes — remove bolts |
| Unlevel / loose feet | Machine rocks when you push a corner | ✅ Yes — level and lock nuts |
| Overloading | Only shakes on stuffed-full loads | ✅ Yes — wash smaller loads |
| Worn shocks / suspension rods | Shakes on balanced loads; drum bounces freely | ❌ Call a technician |
| Failed drum bearing | Loud rumble in spin; drum has play | ❌ Call a technician |
The dividing line is simple: anything you can fix from outside the cabinet — the load, the feet, the shipping bolts — is yours. Anything that requires opening the machine and replacing suspension or bearing components is a service call, both because of the disassembly involved and because the parts are model-specific.
Why you shouldn't just live with it
We get asked this a lot: "it shakes, but it still washes — can I ignore it?" We don't recommend it. Violent vibration accelerates wear on every other part of the machine: it works hose clamps loose, fatigues wiring connections, cracks plastic tub supports, and can walk the machine far enough to yank the drain hose out of the standpipe — at which point you have a draining problem and a wet floor on top of the shaking. A $200 suspension repair now is cheaper than the cascade of failures a shaking machine causes later.
What a washer vibration repair costs
Washing machine repairs run $100–$350 depending on the failed part, and every job starts with a $75 service call that's applied toward the repair. Shock absorbers and suspension rods sit in the middle of that range; drum bearing work sits at the top, and on older machines we'll tell you straight when replacement makes more sense. You'll get a written quote after diagnosis, before any work begins — and a 90-day parts-and-labor warranty after it. When you're ready, GUIFIX handles washing machine repair with same-day appointments available.
Frequently Asked Questions
Why does my washer shake violently on the spin cycle?
The most common causes, in order: an unbalanced load (one heavy item on one side of the drum), unlevel or loose leveling feet, shipping bolts left in a new machine, and worn shock absorbers or suspension rods. The first three are free fixes you can do yourself; worn suspension is a repair.
Is it bad to run a washing machine that shakes a lot?
Yes. Repeated violent shaking strains the suspension, can crack the outer tub, loosen hose connections, and damage internal wiring. It can also walk the machine into walls or pull the drain hose out of the standpipe and flood the floor. Fix the cause before running more loads.
Did I forget to remove the shipping bolts from my new washer?
If a new front-load washer shakes hard on its very first loads, check the back panel for three or four large bolts with plastic spacers. They lock the drum for transport and must come out before use. Running with them in will destroy the suspension — remove them and keep them for future moves.
How much does it cost to fix a washer that shakes?
If the cause is the load, the feet, or shipping bolts, it costs nothing. Replacing shock absorbers or suspension rods is a common repair that typically lands in the $150–$300 range with labor. A failed drum bearing costs more and on an older machine often isn't worth fixing.
