How to passivate stainless steelwith nitric acid

In this story, we’ll tell you quick facts to know, such as what causes a bad wheel bearing, how long you can drive on one, and the estimated replacement cost of a wheel bearing as you maintain your vehicle.

The bearings are tightly packed in a grease-filled, waterproof, sealed metal ring. This housing, called a race, is located inside the hub, and each wheel has one. Wheel bearings have a Herculean responsibility: They are engineered to support the vehicle’s entire weight.

In this post, we’ll explore two effective methods to passivate stainless steel welds—electropolishing and citric acid passivation. Both methods are widely used in the industry and offer unique benefits for achieving a clean, corrosion-resistant surface.

Electropolishing involves immersing the stainless steel part in an electrolyte solution, usually a mix of acids, and then applying a DC electric current. The stainless steel becomes the anode, and material is gradually dissolved from the surface. This process removes free iron, surface oxides, and any imperfections, creating a smooth, highly reflective, and corrosion-resistant surface.

Bad wheel bearings can cause the steering wheel to vibrate. The intensity increases as the vehicle speed increases and the vehicle turns to the left or right. However, the vibration could be linked to an out-of-round tire (there could be a flat spot on the tire) or a tire that is no longer balanced. Another cause is damaged or worn suspension components.

If one tire wears out faster than the others, it could be a sign that the wheel bearings are worn. However, it also could be a sign the tire is improperly inflated (too much air pressure or not enough), the tires are improperly aligned, or the vehicle has damaged or worn suspension components.

Worn bearings may cause a vehicle to pull to the left or right when brakes are applied. The direction the vehicle pulls signals where the worn bearings are located, on the left or right side of the vehicle. However, this can also signal brake rotor or brake caliper problems.

The anti-lock warning light may illuminate if the ring, tire, and wheel wobble, the wheel’s speed sensor is no longer operating properly, and the ABS may operate sporadically or not at all. See a professional for repair.

Driving with bad wheel bearings impacts the safety of a vehicle, and it could cause a serious car accident. We do not advise driving on them when they fail and recommend getting them checked out as soon as possible. Bad wheel bearings can damage things like your hub, the vehicle’s constant velocity joint (CV joint), or the automatic transmission.

Jun 21, 2009 — The bolts/nuts are 3/8" SAE thread (fine) and they are torqued to 35 ft.lb. (9/16" drive tool) Most torque wrenches are rated to be used in 70°F. conditions.

“The good news is most of the time, a vehicle will let you know way before a failure ever happens,” said Gary Hardesty, Kelley Blue Book’s in-house service and maintenance expert and an A.S.E. certified master technician. “The key is to listen to your car. Most times, a failing wheel bearing will exhibit a growling type of noise that changes with vehicle speed. The faster the car (goes), the faster the frequency of the growl.”

By leveraging electropolishing, citric acid passivation, or a combination of both, you can ensure that stainless steel welds stay resilient and corrosion-resistant, even in the most challenging conditions.

Your vehicle will signal that it’s time to replace a failed wheel bearing. For example, if you hear unusual sounds like humming or clicking, then your bearing might be bad. Watch out and listen for these signs and symptoms:

Wheel bearings connect a car’s wheels to the axles. They allow wheels to turn with minimal friction. Though wheel bearings are low-maintenance parts, they are important safety components of a vehicle’s braking, steering, and suspension systems. The one-piece hub assembly, between the drive axle and the brake disc or drums, incorporates the hub, wheel bearings, ABS (anti-lock braking system) wheel speed sensor, and mounting flange.

Hardesty cautions that if you think something is wrong, don’t wait to get it diagnosed: “The longer you wait, the more it will cost as other components may be damaged by a wheel bearing.”

During the welding process, high temperatures disrupt the passive layer on stainless steel, causing impurities to surface and forming oxides that can accelerate corrosion. This process exposes free iron particles and other contaminants, especially in areas near the weld zone, known as the heat-affected zone (HAZ). By passivating the welds, you can remove surface contaminants and restore the protective chromium oxide layer that enhances the corrosion resistance of stainless steel.

However, luxury cars are more expensive to repair. Do note that if bearings go bad at one wheel, replacing the bearings at the other wheel on the same axle is unnecessary. Don’t let someone talk you into work that is not needed. Get the price estimate for wheel bearing replacement for your make and model of car.

The original equipment bearings on your vehicle are engineered for specific loads. Those bigger and wider tires look cool, as do tires with lower tread walls. But they place higher loads on the wheel bearings, possibly resulting in accelerated wear. That could present a safety issue if your wheel bearings fail.

Technicians can check for wheel wobble by putting the vehicle on a lift and manually checking for wheel movement. Typically, it would be impossible to shake the wheel and tire. However, if it moves, the hub assembly needs immediate attention. The tire and wheel can literally come off the vehicle at any time, at any speed, if you don’t repair your vehicle.

Citric acid passivation is an environmentally friendly alternative to nitric acid passivation and is commonly used to enhance corrosion resistance in stainless steel. Unlike electropolishing, citric acid passivation does not involve any electrochemical processes but is still effective in removing contaminants and restoring the passive layer.

Both electropolishing and citric acid passivation offer distinct advantages for treating stainless steel welds, and the best choice depends on the specific application and requirements:

Most vehicles today use sealed hub bearing assemblies that contain roller bearings. While we don’t address these, older cars used tapered roller bearings, which required servicing and preload adjusting to ensure the right amount of end play or axial clearance.

If there is excessive play in the steering, meaning the steering seems less responsive or less precise than normal, worn bearings could be causing the problem. Also, this could be a sign the vehicle needs a wheel alignment. If you have any of the signs listed above, visit a dealer service or auto repair shop.

Imagine driving on the freeway when the left front tire and wheel suddenly break off, sending your out-of-control vehicle skidding across several lanes of 65 mph traffic. This is not an exaggeration. This is reality, and can happen if you fail to notice the signs the wheel bearings are deteriorating and need immediate repairs. Your wheel bearing might be bad if you hear unusual sounds like humming, squeaking, or clicking. Some experts say a bad wheel bearing can sound like a bird chirping. Also, if your car wobbles or pulls to one side, you will want to get it checked.

The most easily identifiable and common symptom of bad wheel bearings is audible. But it can be confusing. For example, the source of a humming noise can be linked to other issues, such as tires and the CV joint.

The typical sounds of worn-out wheel bearings are squealing and/or growling. The sound intensifies as vehicle speed increases. Try to pinpoint the location of the noise because it will identify the location of the worn-out bearings.

If you hear a clicking sound that increases in frequency as the vehicle accelerates, there could be a problem with the wheel hub assembly.

Citric acid passivation is a simple process where the stainless steel part is submerged in a citric acid solution, usually at room temperature. The acid works by dissolving free iron particles and contaminants from the surface. This treatment allows the passive layer of chromium oxide to reform, protecting the steel from corrosion.

For demanding applications, a combination of these methods may be considered: citric acid passivation followed by electropolishing can provide exceptional corrosion protection and a refined finish.
