What is Solid Lubrication

Solid lubrication represents the next evolution in bearing technology, eliminating liquid oil entirely. Dexter’s grease-packed bearings use permanent synthetic compounds that won’t leak, purge, or break down under extreme conditions.

Solid lubrication advantages:

  • No cap maintenance: Sealed-for-life design eliminates oil checks
  • Temperature extremes: Functions -40°F to 400°F without breakdown
  • Water resistance: Repels moisture 10x better than oil bath systems
  • Extended life: 3x service intervals vs. traditional greasing

Unlike oil bath hubs requiring the K71-859-00 cap, solid-packed bearings arrive factory-sealed with moly-disulfide compounds. A construction firm running Dexter 15K axles through muddy job sites reported zero lubrication-related failures after switching from oil bath systems.

Conversion tip: When replacing bearings, specify “Dexter Nev-R-Lube” for permanent lubrication matching your K71-859-00-equipped hubs.

How Often Should I Grease the Wheel Bearings of My Trailer?

K71-859-00 requires excellent maintenance to avoid problems; it’s the same with wheel bearings. A trailer’s wheel bearings are a crucial component and must be well maintained over the year. Regardless of the size of the trailer, it must be routinely maintained to allow it to run at full capacity. Greasing the wheel bearings is a must, but how often should you grease the trailer’s wheel bearings?

A Routine Grease is Necessary

It’s difficult to say for certainty how often a trailer’s wheel bearings should be greased because it depends on the size of the trailer, its weight load, and the wheel size. If nothing else, the bearings should be greased at least every ten thousand miles. This is a golden rule and something you should adhere to. Of course, if you have a relatively smaller trailer and it is used less often, you could stretch to twelve thousand miles before greasing the wheel bearings.

It Depends on Your Trailer

Some trailers require more frequent attention, say every two or three thousand miles rather than ten thousand. For instance, smaller wheels on a boat trailer will typically need to be greased every few thousand miles. Remember, a smaller wheel will spin faster so there is more pressure on them; that will mean the bearings need to be greased more often. It’s the same when your trailer is in constant use or reached its load capacity. Click here to read more about Most Useful Dexter Axle Frequently Asked Questions.

Greasing the Wheel Bearings

Anyone that has worked with a K71-859-00, will know the importance of good maintenance. Greasing the wheel bearings isn’t difficult to do. It’s pretty straightforward actually and little mechanical know-how is required. You’ll need tools, such as a hammer, rags, wheel jack, stands, grease, and a torque wrench to get the job done right.

Greasing the Wheel Bearings

To grease the bearings, you’ll need to jack up the trailer and remove the wheels. (Keep the washer, spindle nut, and retainer safe as you’ll need them to put the wheel back on later.) Pump the grease and rotate the hub. Once this is done, replace the wheel and remove the jack.

Should You Choose the DIY Route or Go to a Mechanic?

Greasing the wheel bearings isn’t difficult to do and will cost far less than if you were to take it to a mechanic. On the other hand, if you don’t know what you’re doing or aren’t able to grease the bearings, a mechanic is the right person for the job. Greasing the wheel bearings needs someone with patience so everything is done correctly.

Good Maintenance Avoids Trouble

In conclusion, proper maintenance of cargo trailer parts, such as the K71-859-00 hubcap and wheel bearings, is essential to ensure safe and efficient operation. Regular greasing of the wheel bearings is crucial, with recommended intervals typically ranging from every ten thousand miles or based on the trailer’s usage and load capacity. Whether opting for DIY maintenance or seeking professional assistance, ensuring the wheel bearings are adequately lubricated is paramount to prevent potential breakdowns and ensure road safety. Remember, prioritizing trailer maintenance not only enhances performance but also prolongs the lifespan of vital components, contributing to a smoother and safer towing experience.
