Yes—an appropriately equipped four-post lift can support wheels-off work. The usual solution is a compatible, properly rated bridge jack that lifts the vehicle clear of the runways.
Understand why the runways alone are not enough
On a standard drive-on four-post lift, the tires carry the vehicle’s weight on the runways. Raising the main lift raises the tires with it. A separate approved lifting device is needed to transfer the relevant load away from the wheels so wheel service can take place.
A bridge jack is designed for this role on compatible equipment. Olympic’s bridge jack collection includes different designs and capacities. Choosing one requires more than matching a product’s headline weight rating.
Confirm the complete equipment combination
Have the lift and accessory supplier verify the exact lift model, jack model, mounting arrangement, adjustment range, lifting-point reach, and vehicle application. The jack’s capacity is separate from the main lift’s capacity. Do not assume each axle carries half the vehicle’s weight or that two jack ratings can simply be added to approve a job.
If a lift is ALI certified, confirm the accessory is approved for that exact certified configuration. The Automotive Lift Institute explains that adding an unrecognized accessory can invalidate the configuration’s certification while it remains altered.
Plan around the actual repair
Tell the supplier whether you want to remove wheels at one end of the vehicle or perform work that leaves more wheels unsupported. Different jobs can require a different approved arrangement. Bring the vehicle details and the intended task to that conversation before buying accessories.
Ask about ground clearance, the vehicle manufacturer’s lifting points, adapter selection, jack travel, and any air supply requirements. A jack that fits between the runways still needs to suit the vehicle and work being performed.
Use the model’s operating procedure
A trained operator must follow the manuals for the lift, bridge jack, and vehicle. Those instructions govern positioning, wheel restraint, lifting-point contact, load limits, mechanical support, and lowering. Use the required load-holding devices; hydraulic pressure alone is not a substitute for the prescribed support.
This article explains the equipment choice, rather than providing a universal wheel-removal sequence. Do not improvise with blocks, unsecured stands, or an ordinary jack placed on a runway unless the manufacturers specifically approve the arrangement.
Consider how often you do wheels-off work
A compatible bridge jack can add useful service capability to a four-post setup. If brakes and suspension are your primary work, compare that complete setup with a suitable two-post lift before deciding.
Find the right combination: Ask Olympic Equipment to check your lift, vehicle, and intended repair. Have the lift model and serial information available, or call 866-774-4531.
