How freely should trailer hubs spin?
The hub should spin freely, with a bit of brake lining drag. There should be a little bit of end play (wobble), but not much. At this point, o make sure the hub is seated properly, back off the castle nut until it is loose. Then tighten the castle nut snugly until it stops.
How often do you Regrease trailer hubs?
Standard tapered trailer wheel bearings are recommended to be re-packed with fresh bearing grease about every year or every 12,000 miles under normal use. In certain conditions this interval could be shorter, such as if you routinely tow the trailer under conditions of extreme heat or near its maximum load capacity.
How often do trailer bearings need to be repacked?
The axle manufacturers recommend that you repack your trailer bearings once annually or every 12,000 km.
How tight should castle nut be on trailer bearing?
Correct Torque Rating for a Trailer Wheel Spindle Nut The nut on the spindle should be tightened until snug, with no side-to-side play in the hub and then backed off slightly, about maybe a 1/8 of a turn.
Should trailer wheels spin freely?
The hub should also spin essentially “freely” with no binding. A heavy drag as you spin it would indicate it is too tight, which could cause the bearing to overheat. The consequence of an overheated bearing could be a failed bearing, or possibly even a failed spindle, either of which is a very bad thing.
How much play should a trailer hub have?
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. If the wheels are loose or spin with a wobble, the bearings must be serviced or replaced.
Can you over grease trailer bearings?
Too much grease volume (overgreasing) in a bearing cavity will cause the rotating bearing elements to begin churning the grease, pushing it out of the way, resulting in energy loss and rising temperatures.
How do I know if my trailer bearings need grease?
If noise is heard, check for a bad bearing or if lubrication is needed. Check for Heat – Tow the trailer for a short distance, 5-10 miles at highways speeds, then park the trailer. Place your hand on each of the wheel hubs of the trailer. If it is too warm to hold your hand in place, you may have a bad bearing.
What happens if you over grease a bearing?
Can you over pack wheel bearings?

In addition, the wheel bearing could actually overheat. Repacking wheel bearings is an easy job, and should be part of the routine maintenance of the vehicle.
Can you over tighten a wheel bearing?
“Excessive preload will cause excessive friction and the bearing will run hot, compromising lubrication and eventually leading to flaking (material coming off) at the large end of the rollers/races,” he says. “On the other hand, adjusting the bearing too loose causes excessive looseness and vibration in the system.
Should I fill my trailer hub with grease?
It is equally important to retain the grease around the bearing. For traditional greases (NLGI Nos. 1 and 2), pump a ring of grease into the entire circumference of the wheel hub and coat the hub cap inner wall. The housing should only be half full of grease.
