Like many repairs, your make and model will influence how much it costs to replace a wheel bearing. Also, expect to pay a bit more for a wheel bearing replacement at a dealership. Possibly much more.

“Subsystem” means a functional grouping of items that combine to perform a major function within an end item, such as electrical power, attitude control, and propulsion.

What countries are notDFARS compliant

A mechanic will sometimes put your car on a lift and then spin a wheel to see how freely it turns. Based on how easily it turns, an experienced mechanic knows if the wheel bearing is shot. A comparison to the other wheel on the other side of the car is also a way to judge. Sometimes you can hear a wheel bearing growling when you spin a wheel on a lift. They are almost always right. However, they may suspect one, and find it is in fact two that need replacing after a test drive. Don’t blame the messenger.

DFARScompliance

“Alloy” means a metal consisting of a mixture of a basic metallic element and one or more metallic, or non-metallic, alloying elements.

A wheel bearing is a component that all vehicles use. There is no advantage to having an EV when it comes to wheel bearings. In fact, EVs are generally heavier than other vehicles in their segment. That is not a good thing for parts that are under the vehicle holding up the load and spinning.

“Electronic device” means an item that operates by controlling the flow of electrons or other electrically charged particles in circuits, using interconnections such as resistors, inductors, capacitors, diodes, switches, transistors, or integrated circuits.

(ii) If two metals are specified in the name (e.g, nickel-iron alloy), those metals are the two predominant elements in the alloy, and together they constitute 50 percent or more of the alloy (by mass).

(B) An amount equivalent to 50 percent of the amount of specialty metal that will be purchased by the Contractor and its subcontractors for use during such period in the production of the commercial derivative military article and the related commercial article.

If your vehicle is still under your bumper-to-bumper warranty, a wheel bearing is likely going to be covered by that new car warranty. Unless there is obvious curb-strike damage. Extended warranties and powertrain warranties don’t usually include wheel bearings. If you have a comprehensive full-whammy extended warranty, it’s worth a try.

(d) Subcontracts. The Contractor shall insert the substance of this clause, including this paragraph (d), in subcontracts and other contractual instruments that are for items containing a covered material, including subcontracts and other contractual instruments for commercial items, unless an exception in paragraph (c) of this clause applies. The Contractor shall not alter this clause other than to identify the appropriate parties.

For DFARS compliant tungsten, supplier certifications must state compliance to 252.225-7052 – Restriction on Acquistion of Certain Magnets and Tungsten. If suppliers are not stating compliance to 252.225-7052, that tungsten is not fully DFARS compliant for use in Department of Defense programs.

(i) A commercial item (as defined in paragraph (1) of the definition of “commercial item” in section 2.101 of the Federal Acquisition Regulation);

At each corner of your vehicle, a wheel bearing is spinning around furiously when your car rolls. The wheel bearing is the part that enables the rotation of the wheels. It is located in the center of the wheel assembly. It consists of a housing and internal roller or ball bearings that are in what are called races, or holders. There is a lubricant in there as well. That lubricant is “for life.” You don’t “lube” a modern wheel bearing. They are also not serviceable in the sense that you can remove, clean, lube, and re-install them. You replace them.

“Electronic component” means an item that operates by controlling the flow of electrons or other electrically charged particles in circuits, using interconnections of electrical devices such as resistors, inductors, capacitors, diodes, switches, transistors, or integrated circuits. The term does not include structural or mechanical parts of an assembly containing an electronic component, and does not include any high performance magnets that may be used in the electronic component.

While the full scope of DFARS is much larger, we’ll focus on how it impacts the acquisition of certain specialty metals, such as tungsten. It is important to note that these rules also now apply to tungsten alloys. Note, however, that a supplier certifying tungsten products only to Specialty Metals DFARS does NOT mean the tungsten meets the latest regulation for tungsten used in DoD programs. Certifications must state compliance to 252.225-7052 – Restriction on Acquisition of Certain Magnets and Tungsten.

(C) Commercially available high performance magnets that contain specialty metal, unless such high performance magnets are incorporated into COTS end items or subsystems; and

(i) Modify paragraph (c)(6) of this clause only as necessary to facilitate management of the minimal content exception at the prime contract level. The minimal content exception does not apply to specialty metals contained in high-performance magnets; and

(iv) All subsequent phases of production of tungsten metal powder, tungsten heavy alloy, or any finished or semi-finished component containing tungsten heavy alloy.

(D) For COTS items that are normally sold in the commercial marketplace with various options, items that include such options are also COTS items. However, if a COTS item is offered to the Government with an option that is not normally offered in the commercial marketplace, that option is subject to the restriction in paragraph (b) of this clause (e.g. – An aircraft is normally sold to the public with an option for installation kits. The Department of Defense requests a military-unique kit. The aircraft is still a COTS item, but the military-unique kit is not a COTS item and must comply with the restriction in paragraph (b) of this clause unless another exception applies).

If you own a vehicle long enough chances are you will need to replace a wheel bearing or two at some point. Unlike routine oil changes, tire rotations, and brake pad and rotor replacements, most consumers don’t know off the top of their heads what replacing a wheel bearing might actually cost. The experts here at Car Talk can help.

Specific to tungsten and its related alloys, recent Department of Defense rules under DFARS place restrictions on the acquisition of tungsten powder and other tungsten products from certain countries. These restrictions also apply to tungsten heavy alloy materials and products.

(A) Specialty metal mill products, such as bar, billet, slab, wire, plate, or sheet, that have not been incorporated into COTS end items, subsystems, assemblies, or components;

Curb strikes, pot-hole strikes, and contamination. These are the biggies. Wheel bearings can live almost indefinitely spinning around and around with a normal load in a clean test lab.

Using Car Talk’s exclusive algorithm, we scoured the world wide web for prices on wheel bearing replacements. The overall average of what we found was between $300 and $500. This is the cost for a mechanic to make it happen, not the cost of the part itself. For part pricing, it is better to search online using your exact year, make, and model. Or connect with your local auto parts store. They may have some good advice about the piece you need and if it is part of an assembly or not. Then you will know better what you are in for, if you're going to do the job yourself.

(ii) If two metals are specified in the name (e.g., nickel-iron alloy), those metals are the two predominant elements in the alloy, and together they constitute 50 percent or more of the alloy (by mass).

(i) For alloys named by a single metallic element (e.g., titanium alloy), it means that the alloy contains 50 percent or more of the named metal (by mass).

(i) For tantalum metal, tantalum alloy, or tungsten heavy alloy, the term “required form” refers to the form of the mill product, such as bar, billet, wire, slab, plate, or sheet, in the grade appropriate for the production of a finished end item to be delivered to the Government under this contract; or a finished component assembled into an end item to be delivered to the Government under the contract.(ii) For samarium-cobalt magnets or neodymium-iron-boron magnets, the term “required form” refers to the form and properties of the magnets.

You can sometimes detect a worn wheel bearing when you drive. The cabin of the vehicle will become louder. You'll start to hear a sort of hum. Not unlike winter tire hum. “That right front wheel bearing is getting loud,” a mechanic might say if she test drives your car. Or, “That bearing is growling.” Crunchy, gnarly, howling, and loose may also be terms to describe a wheel bearing gone bad.

This indicates they can certify to 252.225-7008 and 252.225-7009. They cannot certify to DFAR 252.225-7052 if they are getting material from outside the United States.

(C) If two or more COTS items are combined in such a way that the resultant item is not a COTS item, only the specialty metals involved in joining the COTS items together are subject to the restriction in paragraph (b) of this clause (e.g., a COTS aircraft is outfitted with a COTS engine that is not the COTS engine normally provided with the aircraft).

If your vehicle uses a bearing that can be replaced, the shop will remove the housing, take out the old bearing with a press or by other means, and then put in your new wheel bearing using a press. That takes time. Time is money. Pressing in a wheel bearing is not vaccine science, but it's also not usually a DIY job. If the bearing comes as part of an assembly, it may actually be easier to install and cost just about the same. So don’t panic if you hear “assembly” as part of the job description.

You don’t drive actual roads in a test lab. Your world is full of water and salt and holes that slam your vehicle’s wheels almost constantly. Hit a curb or pothole at a weird angle and the wheel bearing may be stressed in a way it was not meant to be. One rule of thumb some mechanics use is that if you strike something hard enough to damage a rim, you also have damaged your wheel bearing and will need it replaced soon. It often takes some time to discover this. The internal parts are squished or dinged by the impact and they get worse by spinning around for a while, rubbing those internal imperfections into flat spots.

DFARS is a set of regulations, administered by the Department of Defense (DoD). As a well-known set of rules and restrictions on foreign sources of supply, its purpose is to bolster the domestic US industrial base.

“Qualifying country” means any country listed in the definition of “Qualifying country” at 225.003 of the Defense Federal Acquisition Regulation Supplement (DFARS).

The term wheel bearing is not one that has a single meaning. Many shops will say, “You need a wheel bearing,” and what they mean is that you need a wheel bearing assembly that they source as a single part. It includes the housing and the internal bearing itself. Sometimes it is also part of the wheel hub assembly. This is not always a bad thing, by the way.

(iii) Offered to the Government, under this contract or a subcontract at any tier, without modification, in the same form in which it is sold in the commercial marketplace; and

“Alloy” means a metal consisting of a mixture of a basic metallic element and one or more metallic, or non-metallic, alloying elements.

(ii) The restriction on melting and producing of samarium-cobalt magnets is in addition to any applicable restrictions on melting of specialty metals if the clause at 252.225-7009 , Restriction on Acquisition of Certain Articles Containing Specialty Metals, is included in the contract.
