Buying a Used Car Lift: What to Inspect Before You Pay

Buying a used car lift what to inspect comes down to one blunt question: is this machine actually safe to run under a vehicle with a person underneath it, or is it a pile of worn steel wearing a coat of fresh paint? We get calls every month from Iowa shop owners and home garage guys who bought a lift off Craigslist or an auction site, hauled it home, and then called us to ask why it won’t hold pressure or why one arm sags. Most of those problems were visible before the money changed hands. This guide walks through exactly what we look at when we inspect a used lift for a customer, so you can do the same walk-around before you ever load it on a trailer.

Start With the Cables, Chains, and Sheaves

On any 2-post lift, the cables (or chains, depending on the design) are the first thing we check, because they’re also the first thing sellers hope you won’t look at closely. We look for frayed strands, rust pitting, flat spots where a cable has been riding wrong on a sheave, and uneven wear between the left and right side, which tells us the lift has been running out of sync for a while. A lift with mismatched cable tension has usually been abused, not just used.

We also spin every sheave and pulley by hand. If it doesn’t turn freely, or if there’s a groove worn deep enough to feel with a fingernail, that sheave needs replacing before the lift goes back into service. When we’re buying a used car lift what to inspect always includes pulling up the safety cover on the cable drums, because that’s where debris and old grease hide the worst corrosion. A seller who won’t let you pull a cover or won’t let you cycle the lift before purchase is telling you something. Walk away or knock a serious amount off the price to cover the parts and labor you’ll need.

Check the Arms, Pads, and Adapters

Lift arms take a beating over the life of a machine, especially on shop lifts that get used daily. We grab each arm and try to rock it side to side and up and down at the pin. Excessive play means the pins and bushings are worn out, which isn’t a deal breaker on its own but is a real repair cost you should factor into your offer. We also check that the arm restraint or locking mechanism actually engages and holds; a lift that lets its arms swing freely under a car is a hazard no matter how good the rest of the machine looks.

Rubber pads and adapters are cheap and easy to replace, so don’t let cracked or missing pads scare you off a lift that’s otherwise solid — but do use them as a bargaining chip. What matters more is the arm restraint mechanism and the structure of the arm itself. Any bends, cracks in the welds, or previous repair welds on a lift arm are a hard pass for us. We won’t put our name behind a repaired arm, and we don’t recommend our customers run one either.

Test the Hydraulic System Thoroughly

A lift that doesn’t hold at height is either low on fluid, has a bad seal, or has a failing lock/lower valve — and you want to know which before you buy, not after. Ask the seller to raise the lift fully, hold it there for several minutes, and watch for drift. Any downward creep means there’s internal leakage that needs attention. Check the cylinder itself for weeping fluid around the rod seal, and look at the hoses for cracking, bulging, or old repairs wrapped in tape.

We also run the lift up and down a couple of full cycles while listening to the pump motor. Grinding, whining, or a motor that struggles to build pressure usually points to a tired pump or a hydraulic system that’s been run low on fluid for a long time. None of this is necessarily a reason to skip the lift — cylinders and pumps are rebuildable or replaceable — but it should absolutely affect what you’re willing to pay. This is one of the most important parts of buying a used car lift what to inspect, because hydraulic problems are the most expensive to ignore.

Inspect the Concrete Anchoring History

A lift is only as safe as the floor it’s bolted to, and a used lift often comes with a mystery anchoring history. Ask when it was last anchored and to what thickness of concrete. If the seller doesn’t know, plan to treat the reinstall as new and have your slab evaluated. We’ve seen used lifts pulled from locations with cracked or too-thin concrete, and the anchors were the least of the problem — the floor itself wasn’t rated for the load.

Look closely at the base plates for old anchor holes, stress cracks radiating from bolt locations, or shims that were used to level a lift on an uneven floor. Shimming isn’t automatically disqualifying, but it tells you the lift wasn’t installed to spec originally, which raises questions about what else was skipped. When you buy a used lift, budget for a full re-anchor with new anchors rated for your specific slab, regardless of what the seller tells you about the old install.

Verify the Paperwork and Certification History

A used car lift with no manual, no capacity plate, and no service history is a much bigger gamble than one with documentation. The capacity plate matters because it tells you the rated weight and, often, the model number you’ll need for parts. If it’s missing or unreadable, we can usually identify a lift by its structure and components, but it adds time and sometimes guesswork to sourcing the right cables or arms.

Ask if the lift has ever been serviced by a certified lift technician and whether it carries any current ALI (Automotive Lift Institute) inspection sticker. A machine with a documented service history and a recent inspection is worth more and carries less risk than one that’s simply been sitting in a corner of someone’s shop for a decade. If you can get maintenance records, even informal ones, take them — they’ll help whoever installs the lift for you understand its actual condition.

Know What a Full Reinstall Actually Costs

Buyers often forget that the purchase price of a used lift is only part of the total cost. You need transport, a qualified crew to disassemble and reassemble it, new anchors, and likely a handful of wear parts — cables, pads, maybe a hose or two. We walk Iowa customers through this math constantly: a used lift priced low can end up costing close to a new one once professional installation and parts are added in. That’s not a reason to avoid buying used, but it is a reason to get a real installation quote before you commit to a purchase price.

We also strongly recommend having a technician inspect the lift in person before it’s moved, if at all possible. A phone call and photos can catch obvious problems, but a hands-on inspection catches the subtle ones — the ones that turn into safety issues down the road. If you’re weighing a used purchase against a new one, our used vs new car lift buying guide breaks down the numbers side by side, and our used car lift buying guide covers sourcing and negotiating.

Get a Professional Second Opinion Before You Commit

Even after you’ve gone through every item above, it’s worth having someone who installs lifts for a living take a look, especially for a 2-post or 4-post commercial unit where the failure consequences are serious. We do pre-purchase inspections for Iowa customers specifically because we’d rather catch a problem for the price of a service call than have someone call us six months later with a lift that’s unsafe to run. If you’re not local to us, most reputable lift installers in your area offer the same service.

Our more detailed walkthrough, how to inspect a used car lift before buying, goes item by item with more photos and specifics if you want a printable checklist to bring with you. Buying a used car lift what to inspect isn’t complicated once you know where to look, but it does take patience — don’t let a seller rush you through the walk-around, and don’t skip a step because the price seems too good to pass up. The lifts that fail customers are almost always the ones nobody inspected properly.
