Most automotive manufacturers agree that wheel bearing repacking and cleaning should be completed every 30,000 miles or once every other year. … It’s also very common for dirt and debris to seep into the wheel bearing housing either due to brake dust or other contaminants near the wheel hub.
The axle manufacturers recommend that you repack your trailer bearings once annually or every 12,000 km. If you are over-do for trailer wheel bearing maintenance, we would be happy to help you.
FOR STARTERS, note that most sealed bearings come pre-greased from the factory with a 25%-35% grease fill. This is all the grease the bearings will ever need, because the relubrication interval (explained below) is longer than the expected life of the bearing. DON’T JUST GUESS.
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. Too much grease causes churning and higher temperatures.
Depending on the quality of the bearing, they normally last between 85,000 and 100,000 miles. Some premium bearings can be pushed to 150,000 miles.
In general it is fine to clean the exterior of the bearings unless you see a substantial amount of lubricant being expelled from the bearing, in which case, it may be worth while to press in new bearings. That said, sealed bearings are somewhat serviceable.
How Tight Should Spindle Castle Nuts be Tightened 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.
A type of grease used to keep a seal and prime on a pump.
Trailers tend to be cheaper to repack professionally (think $100-$200), but don’t underestimate the power of the upsells a mechanic might try to give you. If you’re serious about cash, you can likely save a few bucks by repacking your bearings yourself.
Cleaning. Next you need to get all the old crap and grease out of your bearing races. The best bet is to use methylated spirit or just soak the bearings in some solvent or alcohol. If you can find a spray-on degreaser, you can blast all the crap out of your bearings to great effect.
Re: What is Best Way to Clean Wheel Bearings
Start by wiping off all the oil or grease you can reach. Then, for mineral and synthetic oils and greases, wipe all surfaces with hydrocarbon solvent such as mineral spirits or kerosene, followed with an isopropyl alcohol wipe.
Repacking a bearing is the process of removing the parts of the wheel to access, clean, and add more grease to the bearing.
It’s really simple but it works wonders on the rear wheel bearings. It has an attachment big enough for front wheel bearings, but the front wheel bearings are integrated with their race so I don’t think this would work because it would just destroy the bearing.
If you have disc brakes, repacking wheel bearings isn’t a difficult job. It’s just that you may not get the calipers back on right, which could cause your brakes to malfunction. If you have drum brakes, go right ahead and repack the bearings yourself.
Most bearing packs are greased by hand as opposed to by machine. And it’s just fine to do that. You just take some high-temp lithium grease in your hand and press the bear pack into it, rotating the pack and repeating the process until you’ve worked it all the way through.
Over lubricating will kill the bearings performance in a casting reel. … If you are using a shielded bearing or an orange seal bearing you can apply the oil to the bearing with the seals/shields intact. If you are using a contact sealed bearing or grease you will need to remove the seals/shields to apply the lubrication.
Breaking the seal
Sealed bearings aren’t really sealed. … You un-seal them, clean them out and regrease them just like we used to do back when hubs, headsets and bottom brackets used loose-ball cup-and-cone setups. This won’t work if the outside of the seal is aluminum. Those deform too much getting them in and out.
Normal motor bearing operating temperatures range from 140° to 160°F. As in all bearing applications, this measurement should be taken at the bearing outer ring. If the outer ring is inaccessible, take the measurement at the housing and add 15° to 20°F to estimate the correct bearing temperature.
