When a small fleet operator in Davenport called us about swapping out an aging alignment rack for a forward four post lift, the first question wasn’t brand loyalty — it was which configuration actually made sense for daily wheel bearing service on a mixed fleet of pickups and cube vans. We install and service Forward lifts across Iowa, and we’ve learned that two shops can order what looks like the same lift on paper and end up with very different day-to-day experiences depending on runway length, rolling jacks, and approach ramps. This article walks through a real side-by-side comparison so you can spec the right one the first time.

Why Wheel Bearing Work Changes the Spec Conversation
Most shops think of a forward four post lift as a drive-on storage and alignment platform, and it is, but wheel bearing service adds a wrinkle. You need the wheels off the ground without pulling the vehicle onto a separate frame lift, which means rolling jacks or a pit jack setup becomes non-negotiable rather than a nice-to-have. In our Davenport conversations, this was the deciding factor between the two configurations we ended up comparing side by side for the fleet manager.
The first configuration was a bare-bones runway setup — good for tire changes and storage, but wheel bearing work meant dragging a floor jack under the frame and hoping the geometry lined up. The second added factory rolling jacks that ride the runways and lift independently at each end. For a fleet doing bearing swaps multiple times a week, the second setup cut labor time noticeably because techs weren’t fighting jack placement on every vehicle. If your shop is weighing a forward four post lift purely as storage versus one that also needs to double as a service platform, this is the first spec question to answer before anything else.
Configuration One: Standard Runway, No Rolling Jacks
The base configuration is what most fleets start with because it’s the lower-cost entry point and it does exactly what a storage or alignment rack needs to do. Two long runways, front wheel-alignment slip plates, and a mechanical lock system at each post. For a Davenport fleet mostly parking vehicles overnight or running occasional alignments, this configuration is plenty.
Where it falls short is exactly where our fleet operator needed help — wheel bearing service. Without rolling jacks, techs have to bring in a separate service jack, position it under the pinch weld or frame rail, and work carefully around the runway structure. It’s doable, and plenty of shops do it this way for years, but it adds ten to fifteen minutes per corner when you’re doing four wheels on a heavier truck. We’ve serviced these standard runway units for years and they hold up fine mechanically — the tradeoff is purely about workflow speed, not durability.
Configuration Two: Runway with Rolling Jacks
The second configuration we compared adds a rolling jack that travels the length of each runway and lifts the vehicle by the frame or pinch weld points, independent of the main platform. This is the setup we’d recommend anytime wheel bearing service, brake work, or suspension jobs are a regular part of the workload rather than the exception.
For the Davenport fleet, this configuration meant a tech could drive on, raise the platform to working height, then use the rolling jack to lift one corner at a time for bearing service without ever touching a separate floor jack. It’s a heavier unit with more moving parts, which means slightly more maintenance attention on cables and pulleys over time — something we flag with every customer at install — but for a shop turning multiple vehicles through bearing service each week, the labor savings pay for the added complexity fast.
Freight, Site Prep, and Install Timing
Every forward four post lift install we quote starts with the same logistics questions, and Davenport is no exception. Do you have a forklift on site, or do we need to bring one? Is the unit shipping direct to your location or to our shop first? Is there a pit, or is this a straight concrete floor install? These aren’t formalities — they change the quote and the lead time significantly.
For a rolling-jack configuration, we also confirm concrete thickness and condition before scheduling, since the additional weight and the anchor pattern for the rolling jack rails need solid concrete underneath. We’ve had jobs delayed because a shop assumed their existing pad from an old two-post lift would work for a four-post footprint, and it didn’t. Lead times on Forward equipment have run several weeks depending on the configuration ordered, so we always tell fleet operators to get the quote request in early, especially if a rolling jack option needs to be special-ordered rather than pulled from stock.
Rolling Jacks and Cable Maintenance Over Time
Once a forward four post lift with rolling jacks is in service, the maintenance conversation shifts to cables, pulleys, and sheaves rather than just the main lift mechanism. We’ve been out to more than one Iowa shop where a corner of the platform starts sticking, and nine times out of ten it traces back to a cable that’s stretched unevenly or a pulley that needs lubrication and adjustment. This isn’t unique to Forward equipment, but the rolling jack configuration has more of these wear points than the basic runway setup.
Our advice to fleet operators running the heavier configuration is simple: build a quarterly lube and inspection check into your maintenance schedule rather than waiting for a corner to visibly stick. Catching a stretched cable or a dry pulley early is a short service call. Letting it go until the platform is binding on one side turns into a bigger repair and, in some cases, downtime you can’t afford on a working fleet lift. We stock replacement cables and pulley hardware for Forward units specifically because this is one of the most common service calls we get on four-post equipment statewide.
Weight Capacity and Fleet Vehicle Mix
The other spec comparison that matters for a Davenport fleet is weight capacity against your actual vehicle mix. A configuration rated for lighter passenger vehicles can technically hold a loaded cube van or a heavier pickup, but you’re operating closer to the margin than you want, especially with rolling jacks lifting a single corner during bearing service. We always ask fleet customers to give us their heaviest regular vehicle, fully loaded if that’s realistic, not just the average.
In the case we’re describing, the fleet ran a mix of half-ton and three-quarter-ton pickups alongside a couple of box trucks used for local delivery. That mix pushed the recommendation toward the higher capacity tier of the two configurations we compared, even though the lighter-duty version would have technically been rated close enough on paper. Buying a little more capacity than your current fleet needs is cheap insurance against a vehicle upgrade down the road, and it’s a lot cheaper than upgrading the lift itself in two years.
Which Configuration Makes Sense for Your Shop
If your shop is mostly parking, storing, or doing occasional alignments, the standard runway configuration of a forward four post lift is a solid, lower-cost choice that we service without hesitation. If wheel bearing service, brake work, or suspension jobs are a weekly occurrence, the rolling jack configuration earns its keep in saved labor time within the first several months of use, even accounting for the added maintenance attention it needs.
We walked the Davenport fleet operator through both configurations with actual numbers on their vehicle mix and service frequency before they committed, and that’s the same process we use with any shop comparing options. A forward four post lift is a long-term investment — most run well over a decade with proper maintenance — so getting the spec right before it ships is worth the extra week of conversation. Whether you’re in Davenport, Boone, or anywhere else in Iowa, we’d rather talk through the comparison up front than have you find out the hard way that the base configuration doesn’t fit your workload.
