Spend your money on the stands, not the jack

Quick answer: A jack that lasts has a serviceable hydraulic system and steel that doesn't flex. Stands that last have clean welds, a positive locking mechanism and a rating that matches your vehicle. Buy the stands like your life depends on them, because it does. The jack is a tool. The stands are safety equipment.

A floor jack is a lifting device. It's not a holding device. Hydraulic seals can leak down, and a car can slip off a saddle. That's why stands exist, and why nobody should ever put any part of their body under a vehicle supported only by a jack. Not for a minute. Not for a quick look.

So this column starts with the stands, and the jack gets the leftovers of your attention. That's backward from how most people shop, which is why a lot of garages have a shiny jack and a pair of stands that make you wince.

Where these usually wear out

On the jack, the hydraulic system is the weak point. Look at the release valve, the piston seals and the ram. A pitted or rusty ram chews up seals. A jack that slowly sinks under load, or won't rise on full pumps, usually has a seal problem or low fluid. Check the maker's manual for what fluid it takes. It's typically jack oil, not brake fluid.

The mechanical parts matter too. Inspect:

• The pivot pins and the lift arm where it meets the frame
• The caster wheels and their axles, since cheap ones flat-spot or seize
• The handle socket, where a sloppy fit leaves you fighting the jack
• The saddle, which should have a rubber pad and a solid, centered cup

On the stands, inspect the welds first. Paint can hide a hairline crack, so look closely at every joint, especially where the legs meet the base and where the post meets the head. Then check the locking mechanism. Ratchet-style stands rely on a pawl engaging teeth. Pin-style stands pass a steel pin through the post. Many people prefer the pin because the engagement is easy to see and doesn't depend on a spring. Either can be good. Look at what's actually holding the load and ask yourself if you'd trust it.

Check the base too. A wide, flat footprint beats a narrow one. A stand that rocks on a flat floor is a stand to return.

The warranty, decoded

Read the actual document before you buy. A line on the box isn't the warranty. The warranty is the paper behind it.

What to read for:

• Length. "Limited lifetime" usually means the life of the product as the maker defines it. Find the definition.
• Parts versus labor. A jack is heavy. If you have to ship it back, who pays the freight, in both directions?
• Wear items. Seals and casters are often carved out. If the part most likely to fail is excluded, the warranty is mostly decoration.
• What voids it. Overloading, the wrong fluid, commercial use and modification are common ones. If you wrench for money on the side, check the commercial-use clause.
• Registration. Some makers want you to register within a set window. Do it the day it arrives, and keep the receipt in the same folder.

For stands, also check the recall record. The Consumer Product Safety Commission publishes recalls at cpsc.gov. Search the brand and the model before you spend a dime. Ten minutes there's cheap insurance.

Can you fix it?

For a floor jack, yes, and it's the reason to buy one worth fixing. Check these:

• Seal kits. Does the maker or a known third party sell one for your exact model? Search the model number plus "seal kit" or "rebuild kit."
• Fasteners. Standard bolts and snap rings mean you can work on it. Rivets and welded housings mean you can't.
• A service manual or exploded diagram. If the maker publishes one, that's a good sign. If it doesn't, a thick forum thread of owners rebuilding the same model is the next best thing.
• Replaceable wheels, handle and saddle pad. These are the parts that wear out in a garage.
• An accessible fill plug. If you can't top off the fluid, you can't maintain it.

Jack stands are different. You don't repair a stand. A bent leg, a cracked weld, a worn locking tooth or a pin with a flat spot means the stand is retired. Cut it up or bend it past use before you throw it out, so somebody doesn't pull it from the curb and trust it. Good stands last because they're built heavy enough that it rarely comes to that. Stand wear is slow. Damage is sudden.

What long-term owners report

You can't know how a jack ages in the first week. Owners can tell you after a year. Here's where to look:

• One-year-later reviews. Search the product page for "after a year" or "two years later." A review that gets updated after the first season is gold.
• The one-star reviews. Skip the shipping complaints. Look for patterns: "won't hold pressure," "sinks overnight," "pin bent," "weld cracked," "handle wobbles." Three people describing the same failure matter more than one angry reviewer.
• Garage and repair forums. Search the model name with the word "leaking." The people who rebuild their own jacks write the honest reviews.
• Dates. A hundred reviews from the launch month tell you nothing about durability.

If you can't find anyone who's owned it for a year, you're the test. Pick something else.

Cost per year of use

Here's a worked example. These numbers are made up to show the math, not quotes. Check current prices.

Say a decent floor jack and a pair of stands costs $280 together. You use them twice a month for oil changes, tire rotations and brake jobs. If they last 20 years, that's about $14 a year, or roughly 58 cents a use.

Now say a bargain set costs $90 and you replace it every four years. Over the same 20 years that's five sets, $450 total, about $22.50 a year. The cheap option costs more and gives you worse equipment every time.

That math assumes the cheap set only wears out. It doesn't account for the one that fails once. You can run your own numbers with the BRO cost-per-use calculator.

Before you buy

1. Find your vehicle's curb weight in the owner's manual, then pick a jack and stands rated well above it. Check whether the stand rating is per stand or per pair. The label says.
2. Check the jack's minimum height against your car's ground clearance, and the maximum lift against what you need for stands.
3. Read the full warranty document. Note the length, wear-item exclusions and who pays shipping.
4. Look up a rebuild kit for the exact model number.
5. Look for a published service manual or exploded diagram.
6. Search the brand and model at cpsc.gov for recalls.
7. Inspect every weld on the stands. Look at the base, the legs and the head.
8. Prefer a locking mechanism you can see engage.
9. Read one-year-later reviews and the one-star pattern.
10. Plan a flat concrete spot to use them. Not asphalt on a hot day, not gravel, not dirt.

Use your owner's manual to find the jack points. Set the wheel chocks. Lift, set the stands, then lower the car onto them.

Then, before you slide under, shove the fender hard. If the car moves, you want to find out while you're still standing. Slide a spare wheel under the frame as a last line of defense. It costs nothing, and you'll be glad you did it the one time it matters.
