To pre-load the bearings, install the spindle washer and spindle nut onto the spindle with the hub and bearings in place. Tighten the spindle nut finger tight (until snug) and then with channel-lock pliers or a crescent wrench, tighten the spindle nut another 1/4 turn or about 15 to 20 ft pounds of torque.
How much play should be in a trailer wheel bearing?
For adequate trailer wheel bearing maintenance, you need to check your bearings on a regular basis. Jack up the trailer and secure it on adequate capacity jack stands. Check wheels for side-to-side looseness – There should be a very slight amount of play in the wheel, typically 1/8-inch or less.
How often do trailer bearings need to be repacked?
How often should you repack your trailer bearings? The axle manufacturers recommend that you repack your trailer bearings once annually or every 12,000 km.
How do I know if my trailer bearings need grease?
Keep your hand on the wheel and spin it. If you feel any motion that is not smooth, hear any noises, or if the wheel does not spin freely, the wheel bearing is defective or needs lubrication.
Can you over grease trailer bearings?
More grease is never the right answer. Overgreasing can actually cause the rollers/balls to slide over the bearing surface rather than roll over them.

LMX Red Grease
A heavy-duty, premium grease rated for just about every application, including marine trailer-wheel bearings. It resists water well and sticks in place, so it's excellent in outdoor applications, but it isn't specially formulated for wheel bearings.
How long do trailer wheel bearings last?
Wheel bearings have an average lifespan of 136,000 to 160,000 km (approximately 85,000 to 100,000 miles). This is only a rule of thumb though, the actual lifespan of a wheel bearing depends on the quality of the wheel bearing and the operating conditions.
What happens when trailer bearings fail?
A damaged wheel bearing does not only cause a vehicle to be shaky and noisy; it can also cost you more money by damaging other nearby parts, and even force your entire wheel to fly off when driving at high speed.
How warm should trailer hubs get?
When loaded correctly, the hubs should feel warm to the touch, not hot. If you cannot keep your hand on the hub comfortably, the bearings are loaded to tight or in need of maintenance.
Can you put too much grease in 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.
Can you over tighten an axle nut?
An axle nut that is too tight will put too much preload on the hub bearings thus diminishing their life expectancy.
What is the axle nut torque spec?
Generally, jam nuts less than 2-5/8" should be torqued to 200-300 lbf-ft; nuts 2-5/8" and over should be torqued to 250-400 lbf-ft. See chart for exact torque specification. The final step is to use a dial indicator to verify the end play or free movement of the tire and wheel assembly along the spindle axis.
How often should bearings be greased?
To prevent corrosion, all bearings should receive grease and be rotated the first of every month. Turn the wheel by hand while greasing bearings. A clean 1/16" bead of grease must appear on each side of each bearing.
Do bearing buddies grease the inner bearing?
Expert Reply: Bearing Buddy pumps grease into the center of the hub all the way back to the grease seal. A double lip seal should be used to prevent grease from blowing out the seal when added.
Is Lithium Grease good for bearings?
Did you know a spray of WD-40 Specialist White Lithium Grease is a great lithium lubricant for bearings? It reduces friction on bearings and helps keep them protected from rust as well. Simply apply by spraying directly onto the area.
Is red and tacky grease good for wheel bearings?
Red N Tacky has a red Lithium Complex Base that is red in color, forming an effective seal to minimize bearing and hub contamination, with resistance to water washout on boat trailers. This item comes in a 14.5 oz tube that will fit into any standard size grease gun.
What is Sri grease?
Chevron SRI grease is a high-temperature, NLGI 2 grade, ball and roller bearing grease designed for a wide range of applications. It is recommended for anti-friction bearings operating at high speeds in high temperatures, or where there is a likelihood of corrosion.
Are bearing buddies a good idea?
Bearing Buddies are a great way to keep grease in a trailer hub. I recommend them as long as you are aware that it's very easy to put too much grease in a hub with these which will blow out the seal. They have no problem being used on longer road trips so the would work well for you.
Should you grease a trailer ball?
You do not need to grease your trailer hitch ball. That is entirely up to you. However, greasing it is recommended. Greasing will help ensure that the trailer hitch ball keeps its structural integrity, and it will help prevent it from squeaking.
Why are my trailer hubs hot?
When a hub heats up it is usually from either inadequate lubrication or a castle nut that is too tight; you confirmed that neither of these applies in your situation. If the trailer is overloaded with more weight on each hub than they are rated for this too can lead to higher hub temperatures.
