NEVER without gloves!

Why is this mechanic using so much red grease bare-handed?! 🤢⚙️ If you drive a vehicle, your wheels spin on massive metal components called wheel bearings. If these bearings ever run dry, the extreme friction will cause the metal to heat up, melt together, and physically snap your axle while you are driving on the highway! To completely prevent this deadly disaster, mechanics have to "pack" the bearings. In this video, the mechanic squeezes a massive amount of thick, high-temperature red grease directly into their bare hand. They then aggressively press and mash the heavy-duty metal bearing into the puddle of grease, forcing the lubrication deep inside the metal rollers! This creates a flawless, frictionless barrier that ensures the heavy wheel spins safely forever!
