A forward four post lift sounds simple on paper until the freight truck actually shows up in your driveway. We got a call last spring from an off-road builder near Iowa City who does overlanding rigs and wheel bearing service on lifted trucks all day long. He’d bought a used lift and wanted it set up right, but nobody had walked him through what it actually takes to get a few thousand pounds of steel off a flatbed and onto his shop floor. That’s where Auto Lift Services comes in — we handle the whole thing, from freight coordination to final calibration, so the lift is safe to drive a truck onto the same week it lands.

Why an Off-Road Builder Needed a Forward Four Post Lift
This customer runs a small overlanding build shop outside Iowa City — bumper swaps, suspension lifts, and a steady stream of wheel bearing service on trucks that see real dirt. A two-post lift works fine for most general repair, but when you’re pulling hubs, torquing wheel bearings to spec, and rolling heavy aftermarket wheel and tire packages on and off, a drive-on four post platform is a lot more forgiving. You don’t have to worry about pinch points on frame rails that have been modified with skid plates and rock sliders.
He’d found a used forward four post lift through a private sale and figured he’d just get it running himself. After looking at the runways, the hydraulic power unit, and the cable routing, we walked him through what a proper setup actually requires — new cables in most cases, a locking mechanism check, and a full recalibration before anyone drives a truck up onto it. That’s a pattern we see constantly with used equipment: the lift looks fine sitting in a photo, but the cables and pulleys are usually the first thing that need attention, especially on a forward four post lift that’s been sitting outside or in an unheated building for a season or two.
Freight, Unloading, and Forklift Logistics in Iowa City
The part most people underestimate is getting the lift off the truck. A four-post platform ships in long, heavy crates — runways, columns, the power unit, hardware — and none of it is light. Before we ever schedule delivery, we ask the same questions every time: do you have a forklift on site, is there a loading dock, and how much clear space is there between the truck and the install location. For this Iowa City job, the shop had a decent gravel pad but no forklift, so we arranged one as part of the job and lined it out as its own item on the quote so the customer could see exactly what that piece cost.
Freight carriers for a forward four post lift usually deliver curbside on a flatbed with no lift gate, which means someone needs equipment on hand to get the crates down safely. We’ve had jobs where a customer assumed the driver would help unload — that’s not how LTL freight works, and finding that out the morning of delivery is a bad way to start an install. We coordinate the freight window, confirm forklift availability ahead of time, and make sure the runways can actually get from the truck to the final position without dragging through mud or scraping a doorway. In this case the columns went in first, then the runways were lifted into place and squared before any cable tensioning started.
Site Prep Before the Lift Arrives
Concrete readiness is the other conversation we have on every four-post quote. A forward four post lift doesn’t need anchor bolts the way a two-post does since it’s freestanding on runways, but the floor still needs to be flat and rated for the load, especially with a vehicle and rolling jacks parked on it. We measured the slab thickness and checked for cracking near the intended footprint before committing to a layout. For this shop, the existing pad was original construction and held up fine, but we’ve turned down installs before where the floor needed work first.
We also talk through clearance — ceiling height with a vehicle raised, distance from the columns to nearby walls or bay doors, and whether the customer wants rolling bridge jacks or a pit-style setup underneath for wheel bearing service. This customer wanted to be able to pull wheels off a raised truck and still have room to roll a tool cart underneath, so we set the runway spacing accordingly before the lift ever went bolted down for good.
Wheel Bearing Service on a Drive-On Four Post
Wheel bearing service is exactly the kind of job a forward four post lift handles better than most alternatives for a shop like this. Drive the truck up the runways, engage the locks, and you’ve got full access underneath without a two-post’s arm and pad setup getting in the way of oversized aftermarket tires. For lifted overland builds specifically, that clearance matters — big tires and long-travel suspension don’t always leave clean pickup points for a two-post’s swing arms.
Once the lift is set and calibrated, we show every customer how to check cable tension, lube points, and lock engagement themselves so small maintenance doesn’t turn into a service call. That’s part of what separates a rushed install from one that holds up. A forward four post lift that’s been leveled correctly and has properly tensioned cables from day one will stay in service a lot longer than one that gets rushed through setup just to get a truck up in the air the same afternoon.
Common Mistakes We Catch With Used Lifts
Buying a used forward four post lift is common in Iowa, and we don’t discourage it — but we do catch the same issues over and over. Old cables that have stretched unevenly, pulleys with worn grooves, and locking mechanisms that don’t engage on all four columns at once are the big three.
