    Does everyone know how to grease a fifth wheel?

    I talked to someone today, the subject of applying grease to a fifth wheel seemed rather elusive to this gentleman. Even the type of grease.

    I buy a tube of red high temp grease. Most grease will work, I happen to like the red and tacky, or wheel bearing grease.

    Pull off the plastic cap, and pop the metal tab out. Begin tapping the tube, metal end down toward fifth wheel, ensuring the grease makes contact with the fifth wheel. It’s an action of dropping/tapping the tube squarely on the surface of the fifth wheel. A quick pull up will suck grease out of the tube and deposit said grease on the fifth wheel. Repeat until the tube is empty.

    Apply most of the grease on the lower 3/4 of the fifth wheel, when backing under your trailer, line up without touching the fifth wheel to the front of the trailer, drop your air bags, back slightly under the trailer, so the whole fifth wheel is under, then air up your bags. Get out and look to see that everything is of the appropriate height, and gently back under/connect with the king pin. If done correctly, you shouldn’t lose all your grease to the front of the trailer, thus avoiding a mess.

    The other method is to buy a tub of wheel bearing grease at your fav auto parts store, apply the desired amount with a stick, such as a paint stirring stick. Back under the trailer as described above.

    How about greasing the entire truck, how often are you guys doing the brakes, driveline, steering shafts, front end and hood hinges? Curious as a new O/O..

    I grease my truck & trailer whenever I feel to it might be after like 4-7k miles, I do change oil every 12-15K miles. So basically once between oil changes for sure, maybe truck twice. It just depends my mood and weather. It's not going to hurt your truck. Most of the time I grease fifth wheel when I do delivery and you need to disconnect.

    Front to back every Saturday is how we did it. Guess what? NOTHING wears out! Even beating up and down bush roads all day long in the dirt and mud. Grease is cheap.

    Guess that extra couple hundred when you spec a truck must be too much for most. Little bit of grease on the jaws and you’re good to go. No boobs of grease falling off the plate on the trailer when you turn.
