Buying a Used Car Lift: The Inspection Checklist We Use

We get calls almost every week from Iowa shop owners and home garage guys who found a used lift on Facebook Marketplace or at an auction and want us to tell them if it’s worth buying. That’s exactly why we built a buying a used car lift inspection checklist we walk through every time, whether we’re inspecting it in person for a customer or talking someone through it over the phone. A used lift can be a great deal, or it can be a liability sitting on your shop floor. The difference almost always comes down to what you check before money changes hands, not after.

Why We Built a Buying a Used Car Lift Inspection Checklist in the First Place

We started keeping a written buying a used car lift inspection checklist because we kept seeing the same mistakes. Someone would buy a two post lift out of a closed shop, haul it home, and call us a month later asking why it groans on the way up or why one side settles faster than the other. By then they’d already paid for it, paid to move it, and sometimes paid to have it half-installed before finding out it needed a full cable set or a new cylinder. A checklist forces you to look at the lift the way an installer does instead of the way a buyer excited about a low price does.

Used equipment isn’t automatically bad. Plenty of the lifts we install for Iowa shops are used units that check out fine and run for another decade with normal maintenance. The problem is that a lift can look clean and painted and still be dangerous underneath, and it can look rough and tired while being completely sound mechanically. A real inspection checklist looks past the paint and gets into the parts that actually hold a vehicle in the air, which is the only part of the purchase that really matters.

Start With the Paperwork, Not the Paint

Before we even walk around a used lift, we ask for the manufacturer, model number, and any service records the seller has. This matters more than most buyers expect. If nobody can tell you what brand or model it is, parts sourcing gets harder and resale value drops. We stick to a brand allowlist for a reason — Rotary and Challenger for commercial two and four post work, BendPak and Atlas for home garage lifts — because parts and support are actually available for these lines here in the Midwest.

Ask when it was last inspected, whether it has ALI certification history, and why it’s being sold. A shop upgrading to heavier capacity is a normal reason. A shop that closed because of a lift failure is a different story entirely, and sellers don’t always volunteer that. Get the serial number and, if possible, call the manufacturer to confirm it isn’t on a recall list. This step alone weeds out a surprising number of units that looked fine in photos.

Cables, Chains, and Sheaves Get the First Real Look

On a two post lift, cables are usually the first thing to fail and the easiest thing to check if you know what you’re looking for. We look for frayed strands, flat spots, rust bloom, and uneven tension between the two sides. On four post and scissor lifts we’re checking the equalizer cables and chains the same way. Any cable that shows visible wire strands sticking out, or any noticeable stretch difference from side to side, means budget for replacement before this lift ever lifts a vehicle.

We also run the carriage up and down slowly by hand if the seller allows it, listening for grinding in the sheaves and watching whether the carriage tracks straight in the column. A lift that wanders or binds partway up usually has a bent column, a worn roller, or a cable that’s about to become a real problem. None of this is expensive to fix if caught early, which is the entire point of doing this walk-through before you buy instead of after.

Hydraulics, Cylinders, and Fluid Condition

Every buying a used car lift inspection checklist we use spends serious time on the hydraulic side because leaks and worn cylinders are common on units that sat unused for a while. We check the cylinder rod for pitting or scoring, look under the base for old fluid stains, and check the reservoir fluid color and level. Dark, gritty fluid usually means seals are on the way out even if there’s no visible leak yet.

We also cycle the lift under a light load if possible and watch for drift once it’s raised. A lift that creeps down on its own, even slowly, has a hydraulic or valve problem that needs attention before it’s trusted with a vehicle. This is one of the more expensive repairs on a used unit, so a seller quoting a low price on a lift with a bad cylinder isn’t actually offering much of a deal once you price the fix.

Arms, Pads, Pins, and Locking Mechanisms

We physically move every arm through its full swing range and check for slop in the pins and bushings. Worn arm pins create play that gets worse under load, and replacement pads that don’t match the vehicle’s lift points are a common sign of a lift that’s been misused. The safety locks matter just as much — every position should engage with a solid mechanical click, and we test that the release actually requires deliberate effort rather than triggering accidentally.

If the locks feel soft, skip a position, or don’t engage evenly on both columns, that lift isn’t ready for daily use regardless of how good the rest of it looks. This is one of the most overlooked steps in any used car lift inspection checklist, and it’s the one item we won’t compromise on when we’re inspecting equipment for a customer here in Iowa.

Concrete Anchoring and Floor Condition at the New Location

A lift can pass every mechanical check and still be unsafe if it goes into a slab that isn’t rated for it. We check the seller’s current anchoring as a reference, but the real question is what your slab looks like at home. Concrete thickness, cure time, and rebar all factor into whether a lift can be anchored safely, and this is the step people skip most often because it happens after the purchase decision is already made.

We’d rather answer this question before you buy than after you’ve already paid to move a lift you can’t legally or safely install. If you’re unsure about your slab, we can talk through what a given lift model needs and whether your shop or garage floor is a fit before you commit to the purchase.

When to Walk Away and When to Call Us Instead

Some used lifts fail enough of this checklist that walking away is the right call — cracked welds, mismatched components from different model years, or a seller who won’t provide a serial number are all red flags we treat as deal breakers. But plenty of used lifts pass with only minor items to address, and those can be excellent value if you know what you’re getting into.

If you want a second set of eyes before you hand over money, our related guides on a used car lift inspection checklist and a used car lift buying checklist go deeper on specific brands and lift types. We also do in-person inspections for buyers across Iowa, and we’d rather tell you not to buy something than watch you install a problem in your own shop.
