If you’re pricing out automotive two post lifts for a home garage in Ankeny, we’d bet the seller’s pitch is all about lifting capacity and arm reach — and almost nobody mentions the cables. We get it. Cables aren’t exciting. But if you’re a weekend guy planning to pull wheels and do your own wheel bearing service, the cable system is exactly what keeps that car level and safe while you’re underneath it with a bearing half out. Before you hand over a deposit on a used or new two post setup, walk through this pre-purchase checklist with us. It’s the same thing our техs check on every install and every used-lift inspection call we run around central Iowa.

Why Cables Matter More on a Wheel Bearing Job
Wheel bearing service is one of the harder jobs you can do on a two post lift because you’re working a corner with the wheel completely off and the suspension hanging loose. That’s a lot of asymmetric weight on one side of the car while the opposite corner is still loaded. On automotive two post lifts, the equalizer cable is what keeps both carriages moving together so the vehicle doesn’t tilt or drop unevenly while you’re torquing a hub. If that cable is stretched, frayed, or has been re-routed wrong at some point, you’ll feel it in a soft or uneven ride as the arms travel — and that’s not something you want happening with a wheel off and your arm inside the knuckle.
We’ve inspected plenty of used lifts around the Des Moines metro where the seller swears everything works fine, and it does, right up until someone actually loads a corner unevenly like you do during bearing work. A worn cable can hold a balanced load and still fail under an off-center one. If you’re buying automotive two post lifts secondhand for exactly this kind of DIY suspension and bearing work, do not skip the cable check just because the lift goes up and down smoothly in the showroom or driveway.
The Pre-Purchase Cable Checklist We Actually Use
When we walk a used two post lift for a buyer in the Ankeny area, we start at the top pulley and work down. First, we look for any broken strands poking out of the cable jacket — even one or two frayed wires means it’s near the end of its life. Second, we check for flat spots or kinks where the cable has been pinched or run over a worn pulley groove; a groove that’s cut too deep will chew a cable apart fast. Third, we pull on the equalizer cable by hand with the lift unloaded to feel for slack that shouldn’t be there.
We also ask the seller when the cables were last replaced, if ever. Most owners have no idea — cables aren’t something people track unless a shop has been doing scheduled service. If nobody can answer that question, we treat the cables as original and price accordingly, because on an older Rotary or Challenger two post that’s been in service ten-plus years, factory cables have almost certainly seen their working life. This is the single most common thing we find wrong on used lift inspections, more than anything with the hydraulics.
Recommended Replacement Intervals
There’s no single mileage number for cables the way there is for motor oil, but we tell customers to plan on inspecting cables every six months and budgeting for replacement somewhere in the three to five year range under regular home-garage use — sooner if the lift sees heavy daily use in a commercial bay. If you’re buying a lift specifically to do your own wheel bearing service, suspension work, or brake jobs where the vehicle sits loaded unevenly for long stretches, we’d lean toward the shorter end of that window.
Cable wear also depends heavily on how the lift was maintained before it got to you. A two post lift that sat outdoors, or in an unheated pole barn with big swings in humidity, ages cables faster than one that lived in a climate-controlled shop. Ask about that history. If the seller can’t tell you, assume worst case and price a fresh cable set into your offer.
What a Bad Cable Actually Looks Like Mid-Job
You don’t always get a clean warning. Sometimes it’s a slight jerk as the arms travel, sometimes it’s one side of the vehicle sitting a half inch lower than the other at full height. On a wheel bearing job specifically, that unevenness matters because you’re already dealing with a wheel off and a hub assembly partially disassembled — the last thing you want is the platform shifting while you’re mid-task. We’ve had customers describe hearing a faint popping or clicking sound as the lift travels, which is often a strand starting to separate inside the cable before it fully lets go.
Concrete, Anchors, and the Rest of the Pre-Purchase Walk
Cables get the headline in this article, but a full pre-purchase check on automotive two post lifts has to cover the anchor bolts and slab too. We’ve been called out plenty of times for lifts that were
