If you’re a weekend mechanic in West Des Moines shopping for automotive two post lifts to handle wheel bearing jobs in your home garage, the cables are the one thing most buyers never think to check until it’s too late. We’ve walked into more than one shop where a used two-post lift looked clean, ran smooth on a quick test lift, and still had cables that were one bad day away from letting a vehicle drop unevenly. Wheel bearing service means the car sits up in the air for a while with someone underneath it, so this isn’t a spot to gamble. Before you hand over cash for a used lift, or even before you finish paying off a new one, know what you’re looking at.

Why Wheel Bearing Work Puts More Stress on Cables Than People Realize
Wheel bearing service isn’t like an oil change where the car’s up and down in ten minutes. You’re pulling a hub, sometimes fighting a stuck bearing with a press or a hammer, and the vehicle can sit at full height for an hour or more with someone’s hands and head near the wheel well. That’s exactly the situation where a marginal cable on a two-post lift becomes a real problem instead of a theoretical one. Vibration from impact guns, side-loading when you’re wrestling a stuck hub, and the simple passage of time all work against a cable that’s already fraying.
We’ve been called out on used automotive two post lifts where the owner noticed the arms weren’t level anymore, and it traced straight back to one cable stretched more than its mate. On a symmetric lift especially, uneven cables mean the platform doesn’t rise level, which shifts load in ways that can put extra strain on the arm you’re currently using to hold a wheel off the ground. For a weekend guy doing his own bearings, that’s not a repair bill risk — that’s a safety risk sitting right at head height.
The Pre-Purchase Cable Checklist We Actually Use
When we go look at a used two-post lift for a customer, cables are near the top of the list right after arm structure. First, we look for visible fraying or broken strands anywhere along the cable run, especially near the sheaves and where the cable clamps to the carriage. Second, we check for rust or discoloration, which tells you the lift sat outside or in a damp shop for a while. Third, we test equalization — run the lift up slowly and watch whether both arms rise together or one lags. A lag of even an inch or two at half travel is a red flag worth negotiating over.
We also ask the seller directly how old the cables are and whether they’ve ever been replaced. Most owners have no idea, which tells you something too. If it’s a Rotary or Forward two-post lift and nobody’s touched the cables since install, and the lift has any real age on it, budget for replacement before you ever raise a vehicle on it. It’s a cheap insurance policy compared to what happens if a cable lets go mid-job.
What Cable Wear Actually Looks Like on a Used Lift
Cables don’t usually snap out of nowhere — they give you warning signs if you know where to look. Fraying shows up as individual wire strands poking out from the main cable body, usually at bend points around pulleys or sheaves. A cable that’s stretched will often show a change in diameter or a slightly different color where it’s been under constant load versus the slack sections. Kinks or flat spots are another giveaway that a cable was overloaded or pinched at some point in its life.
We’ve seen used lifts where the cables looked fine from three feet away but had rust pitting once you got a flashlight and your hand right on them. That pitting weakens the cable from the inside out, and it won’t show up as an obvious problem until the day it does. If you’re doing a pre-purchase check on automotive two post lifts and you can’t get close enough to run your hand along the full length of every cable, that’s a deal point — ask the seller to drop the lift to a lower height so you can actually inspect it properly.
Replacement Intervals: What We Tell Home Garage Customers
There’s no single mileage-style number for cable replacement because it depends on use, environment, and load. But as a general rule for a home garage doing regular wheel bearing and brake work, we tell customers to have cables inspected at least once a year and plan on replacement somewhere in the five to ten year range depending on how heavy the use is. Shops running multiple lifts through daily commercial work will wear cables faster than a hobbyist doing weekend projects, so adjust expectations accordingly.
If you bought a used lift and don’t know its history, treat the cables as due for inspection immediately, and budget for replacement within the first year regardless of how they look. It’s a lot easier to swap cables on your own schedule than to find out they needed it while a car’s sitting at full height. Parts for most Rotary and Challenger two-post lifts are stocked and ready to ship, so this isn’t a job that should sit on a waiting list once you know it’s needed.
Concrete, Bay Width, and Other Pre-Purchase Basics That Matter Just as Much
Cables get the attention here because they’re the sub-topic, but a full pre-purchase checklist on automotive two post lifts doesn’t stop there. We’ve installed used lifts on slabs anywhere from a few inches thick to much heavier commercial pours, and concrete thickness and condition matters as much as anything mechanical. If you’re buying a used two-post lift for a home garage in West Des Moines, get an honest look at your slab thickness before you commit — anchors driving into thin or cracked concrete is a completely separate failure mode from a bad cable, and just as serious.
Bay width and ceiling height matter too. A lift that worked fine in a 30-foot-wide commercial bay might not clear your garage door opener or leave enough swing room for your specific vehicles. We’ve had callers describe needing a base-plate model specifically because an overhead beam would have to route around a garage door opener — that’s a common issue in converted home garages, and it’s worth measuring twice before the lift even shows up on a trailer.
What a Proper Inspection Visit Covers Beyond the Cables
When we send someone out to look at a used two-post lift before purchase, cables are one piece of a bigger picture. We check the safety locks engage cleanly on both arms, we look at the cylinder or hydraulic side for leaks and smooth operation, and we make sure the arms themselves aren’t bent or cracked at the pivot points. A lift that bounces on the way up or down, or that has a safety switch not engaging correctly, needs attention regardless of how the cables look — we’ve fixed exactly that combination on lifts around Iowa more than once.
We also check the posts for plumb and the anchors for any sign of movement in the concrete. None of this replaces a cable inspection, but it rounds out what a real pre-purchase check on automotive two post lifts should include. If you’re not comfortable doing all of this yourself, that’s exactly the kind of visit we do for customers across central Iowa before money changes hands on a used lift.
Getting a Used Lift Installed Right After the Sale
Buying the lift is only half the job — getting it installed correctly is where a lot of the risk from a marginal used unit gets sorted out or made worse. We ask every customer about forklift access, pit clearance if applicable, and concrete condition before we schedule an install, because those logistics decide how smooth the day goes. A used two-post lift that passed your cable check still needs to go in plumb, anchored properly, and calibrated so both sides equalize correctly.
If you’re in West Des Moines or anywhere else in central Iowa and you’ve found a used lift you’re considering, have us take a look before you finalize the deal or at minimum before we install it. We’ll flag cable wear, check the structure, and make sure what you’re buying is actually worth putting a car on. It costs a lot less to catch a problem before the lift is bolted down than after.
