How to Inspect a Used Car Lift Before You Buy It

Knowing how to inspect a used car lift before you hand over cash is the single best way to avoid buying somebody else’s problem. We get calls every month from Iowa shop owners and garage builders who found a lift on Facebook Marketplace or at an auction and want us to install it, only to discover once it’s on our trailer that the columns are bent or the cables are frayed past saving. A used lift can be a great deal, but only if you know exactly what to look for before the money changes hands, not after.

Start With the Columns and Frame

Before you touch a single cable or hose, walk around the lift and look at the structure itself. On a two-post lift, sight down each column from the base to the top — any visible bow, twist, or wave in the steel is a dealbreaker, not a repair project. Columns take enormous side-loading over years of use, and once they’re bent, they’re bent for good. Check the base plates too; look for hairline cracks in the welds and rust bubbling up through the paint, which often means the lift sat outside or in a wet shop for years.

On a four-post, check the runway rails for straightness and look underneath at the crossmembers for rust-through, especially near drain holes where moisture collects. This is one of the most overlooked steps in learning how to inspect a used car lift, because the structure is the one part you genuinely cannot fix cheaply. Everything else — cables, arms, hydraulic parts — we can source and swap. A cracked or bent frame means the lift is scrap, no matter how good a deal the price seems.

Check Every Cable and Chain Closely

Cables are cheap to replace but expensive to ignore. Run your hand along the length of every cable looking and feeling for broken strands, kinks, or flat spots where the cable has been pinched. Any fraying at all means the cable needs replacing before the lift ever goes into service — this isn’t optional wear, it’s a load-bearing safety component. On chain-style four-post lifts, check for stretched links and rust between the plates, and make sure the chain still sits evenly in its sprocket rather than climbing to one side.

Ask the seller directly when the cables were last replaced. If they don’t know, budget for new cables regardless of how they look today, since cable life is usually five to ten years depending on use and environment. We carry replacement cable sets for Rotary, BendPak, and most other major lift brands, so this isn’t a reason to walk away from an otherwise solid lift — it’s just a line item to factor into your offer.

Inspect the Arms, Pads, and Locking Mechanisms

Lift arms should move freely through their full range without binding, grinding, or excessive play in the pivot points. Grab each arm and try to wiggle it side to side; a little movement is normal, but a lot of slop means worn bushings or pins that will need attention. Check that the arm restraints and locking pawls engage cleanly at every height position — a locking mechanism that skips teeth or doesn’t hold under load is a genuine safety issue, not a cosmetic one.

Also look closely at the pads themselves. Cracked, hardened, or missing rubber pads are cheap to replace but tell you something about how well the lift was maintained overall. If the pads are shot, ask yourself what else was neglected. This kind of detail work is exactly what separates a thorough inspection from a quick glance, and it’s a step we always recommend before buying any secondhand lift, not just as a formality.

Test the Hydraulic System

If the seller will let you cycle the lift, do it. Watch for smooth, even movement on both sides — a two-post lift that rises unevenly, hesitates, or drifts down on its own once raised has a hydraulic problem somewhere in the cylinder, hose, or valve system. Look underneath for any signs of oil weeping around seals or fittings. A small amount of residual film is common on an older unit, but active dripping means a seal has failed.

Check the hydraulic fluid itself if you can access the reservoir — it should be relatively clean, not dark and gritty. Contaminated fluid can mean internal wear throughout the system. If the seller won’t let you run the lift at all, that’s a red flag worth taking seriously. Any legitimate seller understands that a buyer needs to see it cycle before making an offer, and refusal to demonstrate it usually means something is being hidden.

Verify the Paperwork and Certification History

A big part of how to inspect a used car lift properly happens away from the equipment entirely — in the paperwork. Ask for the original manufacturer’s data tag, which should still be riveted to the lift and legible. If it’s missing or painted over, that’s a concern, because it tells you the model number, capacity, and manufacture date you need to source correct parts later. Ask whether the lift has ever been ALI-certified or inspected, and request any service or inspection records the seller has.

A lift with a documented service history is worth more and carries far less risk than one with an unknown past. If the seller can’t produce any records at all, treat the purchase as if you’re starting from zero on maintenance and price it accordingly. This paperwork check costs nothing and takes minutes, yet it’s the step most buyers skip entirely.

Confirm the Lift Matches Your Power and Space

Even a mechanically perfect lift is the wrong purchase if it doesn’t fit your garage or shop’s electrical setup. Measure your ceiling height, door clearance, and floor space before you fall in love with a listing, and confirm the voltage and phase the power unit requires against what’s actually available in your building. We see this mistake often — someone buys a great lift, then finds out it needs three-phase power their shop doesn’t have.

Check the concrete too. Most lifts require a minimum slab thickness and cure time, and a used lift pulled from another shop may need anchor points relocated for your specific floor. If you’re unsure what your slab can support, our related guide on buying a used car lift and what to inspect covers concrete requirements in more depth.

Get a Professional Opinion Before You Buy

Even after walking through every step above, there’s real value in having someone who installs lifts for a living take a look before you finalize a purchase. We’ve inspected used lifts for Iowa buyers many times, and it’s common to find a problem the buyer didn’t catch — a subtle column bend, a worn pin, a cracked weld hidden under grime. If you’re serious about buying, a short inspection call before you pay is far cheaper than an install crew showing up to a lift that shouldn’t be reassembled.

Our guide on how to inspect a used lift walks through more brand-specific checkpoints, and we’re always happy to talk through a specific listing over the phone before you commit. Buying used can absolutely be a smart move — you just want the savings to come from a fair price, not from problems you didn’t know to look for.
