If you’re shopping for a car lift and haven’t run through a pre purchase lift checklist yet, stop before you hand over any money. We’ve walked into too many Iowa shops, farms, and home garages where the lift looked fine in a photo but turned out to be a rusted-out liability once we got underneath it. Auto Lift Services is based in Ames, and we install, service, and inspect lifts across the state every week. A solid pre purchase lift checklist takes twenty minutes and can save you thousands in repairs, downtime, or worse — a safety failure with a vehicle in the air.
Already found a used lift? Check part numbers and availability before you buy so replacement cables, arms, or hydraulic units aren’t a guessing game later.
Why a Pre Purchase Lift Checklist Matters More in Iowa
Iowa weather is hard on equipment. Lifts that sat in an unheated pole barn through a few winters, or ones that were used in a shop with road salt tracked in constantly, corrode from the inside out. A pre purchase lift checklist forces you to look past the paint and check the parts that actually fail — cables, hydraulic cylinders, arm pins, and locking mechanisms. We see sellers list a lift as “barely used” when it’s actually been sitting idle for years, which is its own problem since seals dry out and hydraulic fluid breaks down.
Whether you’re buying from a dealer, an auction, or a neighbor upgrading their shop, the checklist doesn’t change. We tell every customer the same thing: a used lift is only a good deal if it’s still safe to run. Running through a pre purchase lift checklist also gives you leverage — if you find cracked welds or a frozen cable, that’s a negotiating point or a walk-away reason, not something to discover after delivery.
Structural and Frame Inspection
Start with the frame and columns. Look for rust bubbling through paint, especially near the base plates and anchor bolts, since that’s where moisture pools. Check for any welds that look like field repairs — factory welds are clean and consistent, while shop patches often mean the lift has already failed once. Any bent columns, twisted arms, or visible cracks are a hard no, no matter how good the price looks.
Next, check that the lift still has its original data tag with a legible capacity rating and serial number. If that tag is missing, you can’t verify the lift’s rated capacity or pull manual and parts info, which makes future service much harder. We’ve had customers buy tag-less lifts only to call us later trying to identify what they actually own. Any real pre purchase lift checklist should include a photo of that tag before the deal closes, because it’s the fastest way to confirm you’re getting what was advertised.
Hydraulic System and Cylinder Condition
Hydraulic problems are the most expensive surprises on a used lift. Ask the seller to run the lift up and down a few times while you watch for smooth, even motion. Jerky movement, one side lagging behind the other, or a lift that won’t hold at height under load are all signs the cylinder or hydraulic pump needs attention. Check under the base and around the cylinder for oil residue — a little weeping is common on older units, but active dripping means a seal has failed.
If you can, ask to see the lift hold a vehicle at full height for several minutes with the power off. Significant drift downward means the check valve or cylinder packing is worn. We stock replacement cylinders and rebuild kits for most major brands, so a bad cylinder isn’t automatically a dealbreaker, but it should absolutely change your offer price. This is one of the most important stops on any pre purchase lift checklist because cylinder work isn’t a weekend DIY job for most shop owners.
Cables, Chains, and Locking Mechanisms
On two-post and four-post lifts, cables and safety locks do the real work of keeping a vehicle safely in the air. Inspect cables for fraying, flat spots, or rust between the strands — any of that means immediate replacement before the lift ever goes into service. Test that the safety locks engage cleanly at multiple heights and release smoothly with the release handle. A lock that sticks or skips a notch is a serious safety issue, not a minor annoyance.
We recommend running your hand along the full length of every cable if the seller allows it, since visual inspection alone misses internal wire breaks. If you’re looking at a four-post or scissor lift, check the rollers and glide blocks that guide the carriage, since worn ones cause uneven lifting side to side. Our team can walk you through this over the phone if you’re standing in front of a lift right now and want a second opinion before you commit.
Electrical and Control Components
Older lifts often have outdated motors, worn contactors, or wiring that doesn’t meet current code. Ask to see the motor run under load and listen for grinding, humming, or repeated tripping of a breaker. Check the control box for corrosion or water intrusion, especially if the lift was stored outside or in a damp building — common in older Iowa outbuildings. A pre purchase lift checklist should also confirm the voltage matches your shop’s electrical setup, since mismatched voltage means an added conversion cost you didn’t budget for.
Don’t skip the foot pedal or up/down switch assembly either. These take a beating over years of use and are cheap to replace new, but a bad one on a used purchase is another sign the lift wasn’t well maintained overall. If several small components are worn simultaneously, that pattern usually points to a lift that was run hard without regular service, which should factor into your final decision and price.
Documentation, Age, and Certification
A trustworthy seller can produce some paperwork — original purchase receipt, past service records, or at least a clear answer on the lift’s age and usage history. Lack of any documentation isn’t automatically disqualifying, but it means you should be more thorough on every other part of your pre purchase lift checklist. Ask directly whether the lift has ever had a certified inspection, and if so, request to see it.
We perform independent lift inspections across Iowa and can certify a used lift’s condition before you finalize a purchase, which is worth the small cost compared to buying blind. Age alone doesn’t disqualify a lift — we’ve serviced twenty-year-old lifts that are in better shape than five-year-old ones because of how they were used and maintained. The paperwork trail just helps you weigh that history accurately instead of guessing.
Installation and Delivery Considerations
Even a perfect lift becomes a liability with a bad installation. Before you buy, confirm the ceiling height, floor thickness, and anchoring requirements for the specific lift model, especially in older Iowa buildings with unknown slab specs. A four-post or two-post lift needs a slab rated for the anchor pull-out force, and guessing on this is how lifts fail during their very first use. This step belongs on every pre purchase lift checklist even though it has nothing to do with the lift itself.
