After installing and servicing lifts across Iowa for years, we’ve noticed the same auto lift common mistakes 7 show up again and again, no matter the shop size or brand of equipment. Some of these mistakes are simple oversights that get caught during our inspections. Others sit unnoticed for months, quietly wearing down cables, anchors, and hydraulic seals until something fails at the worst possible moment. We put this list together because we’d rather you catch these issues on paper than find them the hard way with a vehicle in the air. Whether you run a two-post, four-post, or scissor setup, these seven problems are worth checking against your own equipment today.
Not sure which cable, arm pad, or anchor kit fits your lift? Search by model or give us a call and we’ll match the part to your equipment.
1. Skipping a Proper Concrete Evaluation
The single most common of the auto lift common mistakes 7 we see starts before the lift is even bolted down. Shops assume any concrete slab is good enough, but lifts need a minimum thickness, cure time, and rebar-free anchor zone to hold up under load. We’ve walked into installs where the existing floor was poured decades ago for a much lighter purpose, with cracks already spreading near where anchors needed to go.
Skipping this step doesn’t just risk a failed inspection, it risks the anchors pulling loose under a loaded lift. We always core-test or at minimum visually inspect the slab before setting anchors, and we’ll tell a customer honestly if a pour is needed first. It’s a harder conversation upfront, but it’s far cheaper than dealing with a lift that shifts or fails down the road.
2. Under-Torquing or Over-Torquing Anchor Bolts
Anchor bolts have a specified torque range for a reason, and guessing at it is one of the auto lift common mistakes 7 that’s easy to fix with the right tool. Under-torqued anchors can work loose over time as the lift cycles up and down thousands of times a year. Over-torqued anchors can crack the surrounding concrete, especially in older or thinner slabs, creating a weak spot that grows with every use.
We always torque anchors to the manufacturer’s spec with a calibrated wrench, then double-check them again after the first month of use since new anchors can settle. If you’re doing your own install, don’t eyeball this step. A ten-minute check with the right torque value can prevent a much bigger problem later, and it’s one of the easiest items to verify during a routine inspection.
3. Ignoring Arm Restriction Pads and Locks
Arm restriction pads and locking pins exist to keep the lift arms from swinging or slipping once a vehicle is in position, and skipping them is a mistake we catch often on older two-post equipment. Worn or missing pads let the arms shift slightly under load, which can throw off contact point alignment on the vehicle. That small shift can turn into a bigger safety issue when combined with any other looseness in the system.
These are inexpensive parts to replace, but they’re also easy to forget because the lift still seems to work fine without them. We recommend checking arm locks and pads every time you do a routine inspection, not just when something feels off. If your restriction pads are cracked, glazed, or missing entirely, it’s worth ordering replacements rather than continuing to run without them.
4. Loading the Lift Asymmetrically
Not every vehicle balances the same way, and one of the auto lift common mistakes 7 we address in training is loading a vehicle without accounting for its actual weight distribution. Trucks with heavy rear ends, vehicles with aftermarket parts, or anything with a full tank and toolboxes in the bed can shift the center of gravity further than techs expect. Positioning the arms incorrectly for that load can cause a vehicle to tip or slide during a lift cycle.
We train techs to always check the vehicle manufacturer’s recommended lift points, not just where the arms happen to reach easily. It takes an extra minute to confirm proper placement, but that minute matters when a vehicle carries several thousand pounds of uneven weight. This is especially important with heavier trucks and vans that don’t match the sedan-based habits some techs fall into.
5. Deferring Cable and Hydraulic Maintenance
Cables stretch, hydraulic fluid degrades, and seals wear down over normal use, but shops often push this maintenance back until something visibly fails. We consider this one of the more dangerous auto lift common mistakes 7 because cable and hydraulic issues don’t always show obvious warning signs before they break. A slightly frayed cable can look fine at a glance while it’s actually down to a fraction of its rated strength.
Routine maintenance means checking fluid levels and condition, inspecting cables for fraying or uneven wear, and replacing components on a schedule rather than waiting for failure. If you’re unsure what to look for, our shop lift maintenance guide breaks down what a thorough inspection should include. Waiting until a problem is visible usually means the part failed under load, not before it.
6. Skipping Annual Certified Inspections
Some shops treat the annual inspection as optional paperwork rather than a genuine safety check, which is a mistake that compounds every other issue on this list. A certified inspector catches early-stage wear that a busy shop floor often misses, from hairline cracks in welds to anchor bolts that have started to loosen. Skipping these inspections means small problems go unnoticed until they become expensive or dangerous.
We perform certified inspections across Iowa and consistently find issues shop owners didn’t know existed, even on equipment that seemed to be running fine. An annual inspection isn’t just about compliance, it’s a scheduled opportunity to catch the auto lift common mistakes 7 before they turn into downtime or liability. If it’s been over a year since your last inspection, that’s worth putting on the calendar now.
7. Buying Mismatched or Off-Brand Replacement Parts
The last of the auto lift common mistakes 7 happens after the lift is already installed and running, when a shop grabs a generic cable or arm pad instead of the part built for that specific model. Mismatched parts might fit close enough to install, but they often don’t carry the same load rating or wear the same way as OEM-spec components. That mismatch can create a failure point that’s hard to diagnose later because everything looks correct on the surface.
We stock and source parts matched to the brands we install and service, so you’re not guessing whether a bargain part will hold up. If you’re not sure whether your current part is a correct match, our team can look up your model and confirm before you order anything.
