Do bearing buddies really work?
Bearing Buddies do help at keeping water out of the bearings by keeping them under a slight pressure. They don’t however work well at getting new grease to the bearings themselves. If the rear seal is in good condition, it will not allow the new grease to flow through the bearings.
Does a bearing buddy grease inner bearing?

How do you fill bearing buddy grease?
Can you over grease a wheel bearing?
Too much grease causes churning and higher temperatures. Semi-fluid grease must be used with a vented hub cap. It cannot be packed around the bearing as it will slump. Pump this grease into the wheel hub to the bearing cup (outer race) small inside diameter level at the “3 o’clock” and “9 o’clock” levels.

What does it sound like when wheel bearing is bad?
Squealing & Growling
The classic sounds of a bad wheel bearing are cyclic chirping, squealing and/or growling noise. You can also tell that the sound is related to wheel bearings if it changes in proportion to vehicle speed. The sound can get worse with every turn, or it can disappear momentarily.
Should sealed bearings be greased?
FOR STARTERS, note that most sealed bearings come pre-greased from the factory with a 25%-35% grease fill. However, this effectively destroys the seal’s ability to keep contaminants out of the grease; and too much grease “churns” inside the bearing, generating resistance and leading to rapid heat build-up.

Most of this excess force is caused by improper installation.
What is the main cause of bearing failure?
Lubrication Failure
According to a recent study, up to 80 percent of bearing failures are caused by improper lubrication. This includes insufficient lubrication, use of improper lubricants or excessive temperatures that degrade the lubricant.
How do I know if my tapered bearing is bad?
What happens when bearing fails?
If a wheel bearing goes bad, more friction will be placed on the wheel, and the wheel will start to wobble.

It will sound like metal grinding on metal and will get louder as the vehicle goes faster.
