How to Fix a Floor Jack that Won’t Lift?

How to Fix a Floor Jack that Won't LiftYour floor jack can lift a vehicle that weighs several tons by pushing the handle. Just as you are ready to raise your automobile, you find that your floor jack is not lifting. Your floor jack’s only function is to lift large things, but it is falling to do that either.

It’s impossible to use it in this state since it’s too dangerous. You put yourself and your car in danger, not to mention physical damage. Before getting your automobile back on the road, a few things must be done. If you have a floor jack that won’t lift, what can you do with it? How to fix it?

Why isn’t floor jack lifting, and how to fix it?

If your floor jack isn’t working, there is most likely a problem at the root of it, which you need to find before trying to fix your jack. So what causes the floor jack to fail? And how to fix it?

Check the Weight for Overloading

The first thing to realize is that a floor jack may not always fail to retain pressure owing to a mechanical issue. Many individuals do not realize that every hydraulic jack has a limit. That’s why hydraulic jacks often fail. They can’t bear as much weight. Therefore the system breaks. The jack may elevate the car somewhat. But eventually, it gives way to the weight and let’s go violently.

The lifting capability of floor jacks should be compared to the vehicle’s weight. Most floor jacks include an overload safety valve. This prevents the jack from operating when it is overloaded. A Pittsburgh 3-ton floor jack can only lift three tonnes even if you tried. Exceeding a floor jack’s capacity stresses it, but it also puts you at risk.

Insufficient/Excess Oil

Unsafe oil levels might cause our floor jack to fail. If the hydraulic jack’s oil levels are low, it may not perform properly. Pressure won’t build up if the oil levels are too low. Excess oil may destroy rings and seals, necessitating replacement.

The recommended level for most floor jacks is 3/16 to 1/4 above the reservoir. If you need to top out your tank, make sure you do so with a high-quality oil. If the jack’s oil level is greater than suggested, empty it.

Also, regularly inspect the hydraulic jack for debris or dirt in the oil chamber. Disassemble the floor jack to inspect for any broken components that might cause exterior or interior leaks. Consult a pro if necessary.

Loosen Release Valve

The tool’s failure to hold pressure might be caused by a faulty pressure release valve on an old floor jack. When the valve is broken, worn out, or just not where it should be, the pressure from the oil reservoir will automatically come out of the valve and out of the tank.

You can check some things to make sure your floor jack is working properly. If you find that the hydraulic jack won’t go down or up, you should ensure that it’s not stuck. If it isn’t in the right place, move it to where it should be.

If this was the problem, the jack should work again. However, you shouldn’t have to wait until your floor jack breaks before you start to worry. A jack that is regularly cared for will give the best service.


Now and then, the floor jack should be serviced. This will make sure that it is always in good shape. For example, lubricating all moving parts are one of the most important things. However, most people think that all parts are working efficiently, which is not true. Lubrication makes sure that the jack will work well and smoothly with little friction.


There’s no need to panic now that you know what to do when your floor jack doesn’t work. Just follow the above instructions. Again, the best way to avoid problems and malfunctions is to have your car serviced regularly. Keep your jack clean and dry as much as possible, and have it checked out by a professional at least once a year.

Check your jack’s repair manual and follow the manufacturer’s recommended maintenance procedure if you don’t know what to do when your jack breaks down. To make sure your jack lasts as long as possible and that you get the most for your money, regularly check your floor jack.
