Buying a Used Two Post Lift Checklist: What to Inspect First

Every week we get a call from someone who found a two post lift on Facebook Marketplace or at an auction for a fraction of retail, and they want to know if it’s a deal or a disaster waiting to happen. That’s exactly why we built this buying a used two post lift checklist — because the difference between a lift that runs another fifteen years and one that puts your truck through the floor usually comes down to five or six things most buyers never think to check. We install and service lifts across Iowa every day, and we’d rather you walk into a deal with our checklist in hand than call us after something has already gone wrong.

Start With the Paperwork, Not the Steel

Before you even walk out to look at the equipment, ask for the make, model, and capacity rating off the data tag. Any legitimate seller can tell you this in five seconds. If they can’t, that’s your first red flag, and it belongs at the top of every buying a used two post lift checklist we hand out. No data tag also means no way to confirm the lift hasn’t been modified, welded, or repaired with parts that don’t match the original engineering.

Ask how old the lift is and how it was used — a tire shop lift that ran twenty cycles a day for a decade has a very different wear profile than one that sat in a hobbyist’s garage. Ask if it was ever moved, and if so, who reinstalled it and anchored it. A lift that was pulled out of a shop and reinstalled by someone without training is a completely different risk than one that’s never left its original slab. We always tell buyers: a seller who has service records, anchor inspection reports, or even just an honest answer about maintenance is worth paying a little more for.

Inspect the Cables and Pulleys Closely

Cables are the single most common failure point on an aging two post lift, and they’re also the cheapest thing to check. Look for fraying, kinking, flat spots, or rust along the entire visible length, not just the section near the carriage. Run your hand along them if the seller allows it — you’re feeling for broken strands that can snag skin as easily as they can snap under load. Uneven cable tension between the two columns is another warning sign; it usually means the equalization system needs adjustment or the cables themselves have stretched unevenly over years of use.

Check the pulleys and sheaves for grooving, cracking, or a wobble when the lift cycles. Worn pulleys chew up new cables fast, so if you’re already planning to replace cables as part of your buying a used two post lift checklist, budget for pulleys too if they look rough. We stock cable and pulley kits for most major brands, and swapping them out before you ever put a vehicle on the lift is far cheaper insurance than finding out the hard way.

Check the Columns for Twist, Rust, and Anchor Damage

Walk the full height of both columns and look for any twisting, bowing, or bolted-on repairs that weren’t part of the original design. Surface rust on the outside is usually cosmetic, but rust bleeding out from bolt holes or seams often means moisture has been sitting inside the column, which can hide corrosion you can’t see from outside. Compare the two columns side by side — if one leans differently than the other or the carriage doesn’t sit level, something has shifted or the anchoring was never right.

If the lift is still bolted down, ask to see the anchor bolts and the concrete around them. Cracked or crumbling concrete near the base, elongated anchor holes, or bolts that spin freely are signs the lift has been working against its foundation, which stresses the columns and safety locks in ways that aren’t always visible from a quick glance. This is one of the most overlooked steps on any buying a used two post lift checklist, and it’s also one of the reasons we always recommend a professional reinstall rather than a DIY move.

Test the Arms, Locks, and Safety Systems

Cycle the lift up and down if you’re able to, and pay attention to how the arms move. They should extend and retract smoothly without grinding, sticking, or excessive play at the pads. Check the arm restriction pins and locking mechanisms — worn pin holes or bent restraints mean the arms won’t lock securely under a vehicle, which is a serious safety issue rather than a cosmetic one.

Test the safety locks on both columns by raising the lift partway and watching how the mechanical locks engage as it descends slightly. They should catch cleanly and evenly on both sides at the same height. If one side locks noticeably before the other, the equalization cables are out of adjustment, which ties right back into the cable inspection step. A lift with mismatched locks isn’t unsafe to fix, but it does need attention before it ever supports a vehicle in your shop.

Look at the Hydraulic System and Power Unit

Check the power unit for leaks around the cylinder, hoses, and fittings, and ask when the hydraulic fluid was last changed. Old, contaminated fluid accelerates wear on seals and valves, and a lift that’s been sitting unused for a year or more often needs a fluid change and a full seal inspection before it’s trusted with real weight. Listen for excessive noise when the pump runs — a healthy unit hums, while a struggling one whines or labors.

Ask whether the lift has ever had a cylinder rebuilt or replaced, since that’s a good indicator of how hard it’s been used. We carry high-efficiency replacement cylinders for most major brands, so even if the current one is tired, it doesn’t have to be a dealbreaker — just a number to factor into your offer.

Verify the Lift Matches Your Ceiling and Bay Layout

A great deal on paper falls apart fast if the lift doesn’t fit your building. Measure your ceiling height with the lift fully extended, check overhead obstructions like ductwork or garage door tracks, and confirm your floor’s slab thickness and condition can support the anchoring requirements for that model’s capacity. Two post lifts also need clearance on both sides for the columns and swing-arm reach, so measure your bay width before you fall in love with a listing.

Get a Professional Inspection Before You Commit

Even with a thorough visual check, some wear only shows up under a trained eye — internal cylinder condition, hidden column corrosion, or anchor engineering that doesn’t match your slab. We offer inspections across Iowa for exactly this reason, and it’s the last step on our buying a used two post lift checklist that we consider non-negotiable for anything approaching commercial use.
