Wheel bearings are always under constant pressure, even when the car is parked. So if you want a wheel hub bearing assembly to last as long as possible, get a high quality unit like GMB. Read more about GMB wheel hub bearing assemblies here.

If you keep driving with a bad refurbished hub assembly, the bearing will wear out faster than it should. It’s better to play it safe and replace it with a high quality bearing assembly.

Are you using a refurbished (or a cheap aftermarket) wheel hub bearing assembly? Do you notice stiffness? If your answer to both questions is yes, chances are the hub bearing assembly is the problem. Sometimes the bearings inside are too thick to move. The best way to determine if the hub assembly is the issue is to listen for any strange noises like:

In order to find the total valence electrons in a CF2S molecule, first of all you should know the valence electrons present in carbon atom, sulfur atom as well as fluorine atom.(Valence electrons are the electrons that are present in the outermost orbit of any atom.)

The CF2S molecule has a total 24 valence electrons and all these valence electrons are used in the above sketch of CF2S.

You can use a snap bore gauge to check the bore for roundness. You want the gauge to rotate easily within the bore. If you find any debris or corrosion, clean it out. If you install the new bearing in an imperfect bore, it won’t seat the right way. This will result in stiffness and eventual bearing failure.

Did you notice some stiffness when installing a new wheel hub bearing assembly? If so, you may worry that there’s something wrong with the new assembly. Most likely you have nothing to worry about. Yet, you still need to make sure that nothing went wrong during the installation process.

In other words, expensive, mineral oil-based grease with different additives. It’s important for the grease to have high viscosity. Your wheel bearing is a bit stiff after installation because the grease hasn’t worn in enough. A few miles after installation, and it will be OK. Certain elements in the pre-filled grease will break down and allow the bearing to turn normally.

Now to make this carbon atom stable, you have to shift the electron pair from the outer sulfur atom so that the carbon atom can have 8 electrons (i.e octet).

We strongly caution against using refurbished wheel hub bearing assemblies. It’s quite tricky to refurbish one. You have to make sure that all the clearances are right. While you can reuse the drum, you should never reuse the bearing itself. It’s possible for a manufacturer to refurbish hub assemblies the wrong way. The chances of running into issues with a refurbished hub assembly is pretty high.

You can see the electronegativity values of carbon atom (C), sulfur atom (S) and fluorine atoms (F) in the above periodic table.

If we compare the electronegativity values of carbon atom (C), sulfur atom (S) and fluorine atoms (F) then the carbon atom is less electronegative.

Now in the CF2S molecule, you have to put the electron pairs between the carbon (C) & sulfur (S) atom and between the carbon (C) & fluorine (F) atoms.

Here, I’ll tell you how you can easily find the valence electrons of carbon, sulfur as well as fluorine using a periodic table.

In the above lewis dot structure of CF2S, you can also represent each bonding electron pair (:) as a single bond (|). By doing so, you will get the following lewis structure of CF2S.

Is it normal for a new wheel hub bearing assembly to be stiff and hard to turn? Yes and no. In some cases, it’s normal. In other cases, it’s not.

CF2S lewis structure has a Carbon atom (C) at the center which is surrounded by two Fluorine atoms (F) and one Sulfur atom (S). There is a double bond between the Carbon (C) & Sulfur (S) atom and a single bond between the Carbon (C) and Fluorine (F) atoms.

From the above calculations of formal charge, you can see that the carbon (C) atom, sulfur (S) atom as well as fluorine (F) atoms have a “zero” formal charge.

This is a good example of why quality is very important when it comes to wheel hub bearing assemblies. You can’t go wrong with a GMB wheel hub bearing assembly. At GMB, we make OE-quality bearing assemblies with:

Cf2sformula

In short, now you have to find the formal charge on carbon (C) atom, sulfur (S) atom as well as fluorine (F) atoms present in the CF2S molecule.

It can be normal for some wheel bearings to be stiff and hard to turn right after installation. That’s because some manufacturers pre-fill the hub units and sealed bearings with high quality bearing grease. They use automated machinery to inject the grease, because they know that greasing bearings by hand is a chore, and that it won’t always be done well.

For Fluorine (F) atom:Valence electron = 7 (because fluorine is in group 17)Bonding electrons = 2Nonbonding electrons = 6

After shifting this electron pair, the central carbon atom will get 2 more electrons and thus its total electrons will become 8.

If you use an OEM or a high end OE-quality wheel hub bearing assembly, you have nothing to worry about. If you use a refurbished or a cheap aftermarket assembly, the stiffness may be a problem.

You want to make sure there is no debris or imperfections in the bearing bore or axle surfaces (that come in contact with the bearing). Any debris or imperfections in those areas can keep the bearing from seating properly.

Total valence electrons in CF2S molecule = valence electrons given by 1 carbon atom + valence electrons given by 1 sulfur atom + valence electrons given by 2 fluorine atoms = 4 + 6 + 7(2) = 24.

If you haven’t understood anything from the above image of CF2S lewis structure, then just stick with me and you will get the detailed step by step explanation on drawing a lewis structure of CF2S.

This indicates that the above lewis structure of CF2S is stable and there is no further change in the above structure of CF2S.

(Note: In step 5, if we had moved the electron pair from the fluorine atom, then there will be +1 and -1 charges on fluorine and sulfur respectively. But here we move the electron pair from the sulfur atom, which gives the more stable structure (having “zero” charges on all the atoms.))

You can see the number of bonding electrons and nonbonding electrons for each atom of CF2S molecule in the image given below.
