An Ankeny homeowner called us last spring about one of the bendpak 4 post lifts we had installed a decade earlier, worried about the frayed strand he had spotted on one cable during a brake job. That single phone call kicked off the piece you are reading. Cable inspection is not glamorous, and it is not something most first-time four-post buyers think about until year six or seven. But if you own a home-garage four-post and you are doing your own brake pads, rotor swaps, and calipers on it, the cables are the safety-critical component you should know inside and out. This is that guide.
Ankeny and Des Moines metro home garages — our Ames install crew handles delivery, anchor certification, cable inspection, and warranty follow-through on every four-post we set.
Why Cables Are the Component That Matters
A four-post lift raises and lowers on four steel cables that run over sheaves at the top of each column. Those cables carry the entire deck load through every raise-and-lower cycle. They are not decorative — they are the primary lifting element, and they are what you inspect if you want the lift to keep doing what it did on day one. Everything else — the pump, the cylinder, the safety locks — plays a supporting role. The cables are the star.
On a home-garage four-post cycling maybe two hundred times a year for brake work and storage, the cables have a very long service life. But that life is not infinite, and it depends heavily on environment. An Ankeny detached shop with heat and a dehumidifier is much kinder to cables than an unheated garage that swings from ninety-degree summer humidity to sub-zero winter. When we spec bendpak 4 post lifts for the Des Moines metro, the first environmental question we ask is about heat and moisture, because that determines how often you should be inspecting cables.
The Home-Garage Inspection Schedule
For a typical Ankeny home garage running a four-post at a couple of raises per week, we recommend a quick visual cable check every ninety days and a detailed inspection annually. Ninety-day quick checks are five minutes with a flashlight and a rag — you wipe the cable from top to bottom looking for broken strands, kinks, corrosion, and lubrication condition. Annual inspection is a bit more thorough: you run the lift up to about mid-travel, then check each cable at the sheave contact point, at the equalizer, and at the anchor termination on the top of the column.
Homeowners who do their own brake service on bendpak 4 post lifts are already in the garage often enough that the ninety-day check basically happens by itself if you build the habit. Every time you set up the lift for a brake job, glance at each cable while the lift is coming up. If you see a broken strand, a kink, or heavy corrosion, stop and call us. Better one phone call to Ames than a bad surprise mid-lift with a rotor half off. This is the single most important habit we can teach a home-garage buyer.
What to Look For During a Real Inspection
Broken strands are the first red flag. A single broken wire in a strand is not an immediate emergency, but it is a warning. Two or more broken wires in a single strand, or three or more distributed across a cable, is a replacement signal. Kinks are worse than broken wires — a kinked cable is compromised structurally even if no strand has visibly failed. If you see a kink, stop using the lift until we have looked at it.
Corrosion shows up as reddish-brown dust in the strand valleys. Some surface bloom is normal in a humid garage; heavy pitting is not. Lubrication is the last thing to check — a well-lubricated cable feels slightly waxy and has no dry spots. A dry cable that squeaks over the sheave is losing service life every cycle. On bendpak 4 post lifts kept in a heated Ankeny detached shop, we typically see cables looking essentially new at the ten-year mark, which is a testament to what a controlled environment does for wire rope life.
Brake Service Habits That Save Cables
Brake service does not directly hurt cables, but the way you position the vehicle can. When you raise the lift for a brake job, do not stop the lift at the bottom of a lock notch and then jam a rolling jack against a runway. Bring the deck up to a comfortable lock height, drop it into the lock, and then place your rolling jack under the crossmember to free the wheels. That way the cables are unloaded at the safety lock and are not under tension while you swing rotors on and off.
The habit that quietly extends cable life on home-garage bendpak 4 post lifts is simple: do not sit at fully loaded tension for hours. If you are storing a project car up top for a season, lower the lift onto the top safety lock so the cables are unloaded. It is a five-second habit that adds years to cable service life. Most owner’s manuals cover this and most owners never read it. If you do nothing else on your four-post, do that one thing consistently. It is the cheapest maintenance you will ever perform on any lift.
When to Replace Instead of Inspect
Replacement time is not a fixed year on the calendar; it is a condition threshold. If you find three or more broken wires distributed across a single cable, if you find any kink, if you find heavy pitting corrosion, or if the cable diameter has measurably reduced below spec, it is replacement time. Do not try to nurse a marginal cable through one more season. Replacement is the cheapest safety upgrade on the entire lift.
When we replace cables on bendpak 4 post lifts in the Ankeny area, we bring a full four-cable set, an equalizer inspection, a fresh set of sheave grease, and a torque wrench. We pull the deck to its top lock, unload the cables, swap them, tension them evenly, and cycle the lift under load to verify even travel. The whole job is usually a half-day. Compared to the price of a lift replacement, cable service is a trivial line item — the kind of maintenance that keeps a well-built lift running for another decade.
What a Cable Replacement Actually Costs
We do not publish exact dollar figures because they move with steel prices, but a cable set for a common home-storage four-post falls in a modest-to-moderate range, and the labor is a half-day. You will not spend anywhere near what a new lift costs, and you get another decade of reliable service in return. That is one of the reasons we push customers toward well-supported bendpak 4 post lifts in the first place — because when service time comes, the parts exist, the labor is straightforward, and the lift keeps living.
Compare that to a discount import lift where cable sets require an overseas order, sheaves might not match up, and equalizer geometry could be different from what your service tech expects. The cost of a cable replacement on an unsupported lift is often three times higher and takes three times longer to schedule. That is the hidden cost of the bargain lift — it shows up not on invoice day but on year-seven maintenance day. The right lift makes maintenance boring, and boring maintenance is what you want.
Bringing It All Together in Ankeny
If you are an Ankeny homeowner running a four-post for brake service, rotor swaps, and general garage-time, cable inspection is the one maintenance habit that separates lifts that live forever from lifts that get retired at year twelve. Build the ninety-day visual check into your normal brake-service routine, do the annual detailed inspection each spring, unload the cables when you park the project car up top for a season, and call us when anything looks off. Those four habits carry a home lift through decades of service without drama.
Every time we sell one of the home-storage bendpak 4 post lifts to an Ankeny customer, we hand them a printed cable-inspection guide with drawings and a maintenance log. If you already own a four-post and you have never done a cable inspection, call us and we will come out for the first one. We will show you what to look for, how to feel the cable for lubrication condition, and how to spot a broken strand before it becomes a broken cable. That first inspection is what makes every future one easy.
