• Troubleshooting Boat Trailer Rim Getting Hot
  More than likely your tire blow out was due to the age along with the current heat here in the summer. I'm not sure how old they were exactly but a tire typically lasts 3-6 years. A tire blowout typically comes from excessive heat from underinflation, overloading, exceeding the speed rating, or flat spots/sidewall rubbing. Considering the fact that you took the trailer to a shop for replacement parts, and also had them double check once you noticed the heat, I would say you have nothing...

• One Trailer Brake Assembly Heats Up But Stops When Brakes Are Disconnected
  From what you describe, it sounds as if you might have a combination of two separate issues happening. I suspect that you have one trailer brake assembly that's adjusted a bit further out than the others, combined with either a faulty brake controller that's putting out voltage when it shouldn't or corrosion that has built up in the trailer connector allowing power from a different circuit such as the 12-v supply to the trailer to bridge to the brake circuit. An out of adjustment brake...

• How to Determine Bearing Dimensions to Select Replacement Trailer Hub
  My bearing cross reference does not include the Bower bearing numbers BT1151 and T09074 so in order to see if we have a hub that uses compatible bearings you'll want to measure your spindles at the points C and D shown in the linked image. These are the points on the spindle where the inner and outer bearings ride. You will need a precision digital caliper, so that you can measure precisely to the nearest thousandth of an inch, such as 1.234-inches. A new hub must use tapered roller bearings...

• How Tight Should Spindle Nut On Dexter 7000lb Axle Be?
  When you say "Slack" what exactly do you mean? It is normal and required for the bearings to have some slack to allow the wheel to turn without too much friction, and you should be able to rock the hub back and forth and feel slight movement. When installing the hub you should tighten the spindle nut all the way and then back it off one to two notches back. That sounds like how you have it so it should be about right. Just make sure you are not having an abnormal amount of hub movement. I...

• Spindle Nut Torque For Installing Trailer Hub that Won't Cause Hub to Heat Up
  The spindle nut that holds on a trailer hub needs to be just tight enough that it seats the bearings and everything is held in place but not tight enough to create friction and heat like you are experiencing. When our installers replace a trailer hub, there isn't a set torque spec used when tightening the spindle nut. The hub is placed on the spindle, making sure the inner and outer bearings are correctly seated. The spindle nut is then run down until you start feeling resistance. At...

• How to Test Individual Trailer Brake Magnets with Battery and Circuit Tester
  Testing individual brake magnets for proper function can be accomplished by severing the magnet wires and connecting the ammeter between the positive terminal of a 12-volt battery and one of the magnet wires; it does not matter which one. Then connect the other magnet wire to the negative battery terminal. Check the amperage. If the amperage is greater than the specified amount (see specifications below), replace the magnet. If the reading is less than the specified amount, the leads are...

• Are the Bearings and Seal for the Dexter Trailer Idler Hub Dexter Brand
  The included bearings and seal with the Dexter Trailer Idler Hub Assembly, # 34822545BX, were included with the hub from Dexter. Therefore, the bearings and seal are Dexter approved parts. Dexter does not manufacturer their bearings and seals for there hubs, but use the highest quality products from vendors with their products.

• Trailer Hub Assembly Must be Put Together and Packed with Grease
  The trailer hub assembly, part number, 34822545BX, comes with the race attached to the hub. The seal and bearings are not attached. Those parts must be assembled and packed with grease prior to installing the cap. I have attached a FAQ sheet for wheel bearings and two videos for your review.

• How to Choose the Correct Hub Assembly for Jet Ski Trailer
  There is no list of parts available for each year, make and model of trailer. In order to find the correct replacement hubs for your 2007 Triton, you need to know the weight rating of your axle, and also what bearings your current hub has. You will need to take apart your current hub assembly and look at the bearings themselves; wipe away the grease and you should be able to see the part number stamped directly on them. If you are unable to find them, you need to use a digital caliper and...

• Troubleshooting Oil Bath Hub Running Hot
  If that hub has sufficient oil in it then a hub running hot means that either the brake kit isn't adjusted properly or there is something wrong internally like a damaged bearing that is grinding metal instead of just rolling on it. To check the brakes (if you have them) you should be able to freely spin the wheel when it's suspended but you should have some drag. If the brakes check out then you need to pull the hub and inspect the internal components of it. Look for any abnormal wear...

• Hubs and Wheel Bearings Keep Working Loose Causing Play in the Wheels
  It sounds like the problem you are having is related to one of the possibilities you have mentioned. It is nearly impossible to press a race in straight at home unless you have the proper equipment and have done it before. Taking the drums to a brake shop might be the best option to make sure the races are seated properly. If they are seated properly then it is possible that the hub bore could be off causing the races to get out of position. The solution would be to replace the drums. If...

• Should Spindle Be Replaced After Wheel Came Off Weekend Warrior Tri-Axle Trailer
  Now would be a really good time to have the entire system inspected by a qualified shop. If the lug nuts were not tightened properly that could cause the wheel to come off the trailer. The bearing should have been inspected for obvious signs of wear or damage as well as the spindle. If the hub came off with the wheel and tire I imagine the threads on the spindle have been damaged. I would have someone inspect the entire system and replace or repair anything that is worn or damaged. Since...

• Where to Measure on Trailer Spindle to Pick Out Replacement Hub
  Are you sure about the inner diameters of the bearings? Since you said it's a Dexter we should have a solution unless this is a mobile home axle. Typically Dexter spindles have an inner diameter of 1.38 and an outer diameter of 1.06 where spindles ride or have inner diameter that is 1.74 and outer diameter that is 1.25 inch so it seems you might be measuring wrong place. Especially since the seal diameter of the first spindle dimension set I mentions is 1.73 inches. Check out the picture...

• Troubleshooting Overheating Hubs on a Trailer With New Bearings and Grease
  Hubs will heat up when driving, but if it feels like they are getting too hot, then you will want to look at a few things on your hub. My guess is that the spindle nut is too tight and the added stress on the bearings is overheating the bearings and hub and could be causing damage to the bearings. When you install the castle nut you will want to tighten the spindle nut while turning the hub. When there is a slight bind on the bearing, the parts are seated correctly. Back the nut off...

• How to Pick Out Replacement Bearings/Bearing Kit for 2004 Triton XLT
  To pick out bearings for a trailer hub you will need to remove one of the hubs so that you can remove the bearings and get the numbers off of them. Or, you can measure the spindle where the bearings and seal ride so that we can pick you out the correct bearings that would fit the spindle. With either info mentioned I can get you the correct parts you'd need.

• Troubleshooting Trailer Brake Assembly that Is Hotter Than Others and Dragging Brake
  The grease shouldn't be getting hot enough to cause the Bearing Buddy Seal to bulge. That is due to the hub being over-filled with grease. I'd pull that hub off and inspect the brake assemblies as it sounds like something mechanical is going wrong or the drum itself wasn't turned properly. It wouldn't be possible for that assembly to somehow receive more hydraulic pressure than the others so it has to be a mechanical issue.

• Why Would Trailer Hub Get Hot When Leaking Grease/Oil
  If the oil or grease of your hub is leaking out then the heat you have found is related to that. Without proper lubrication the hub is getting hot. If this is a grease hub and you put oil in it then that would be why it would be leaking out. Or you overfilled the hub with grease and in doing so blew out the seal. This is a common problem with people who use Bearing Buddies. Either way you need to replace the seal and repack the hub with grease properly. I attached a video that demonstrates...

• Can Jayco Pop Up Trailer with 4 Lug Hubs be Swapped to 5 Lug Hubs
  Since you have a 4 on 4 inch bolt pattern currently that would indicate that you have a 2,000 lb axle so you could swap your current hubs pretty easily with the bolt pattern you are looking for with the part # 34822545BX that you referenced. This hub comes pre-greased and ready to install as well.

• Troubleshooting Trailer Hub that Gets Warms
  If the bearings are good and the hub is greased properly that basically limits the issue to the brakes. How much drag can you feel as you turn the wheel by hand with the trailer jacked up in the air? It should feel like a light drag and turn easily. Do all hubs get warm or just the one? To see how to manually adjust trailer brake assemblies check out the video I attached, fast-forward to the 4:35 mark of the video. Basically you will adjust the brakes out so that there is a slight but...

• Troubleshooting Trailer Hub/Drum that Gets Hot Ater New Bearings and Assembly Adjustment
  If the adjustment and bearings are good you need to go in and check out what the inside of the hub drum looks like as it may have a wear issue that's causing heat to build up. While in there you'd want to check out everything in the brake assemblies too to make sure there's nothing broken or worn out as well.

• What Limits the Speed of a Trailer
  What limits the speed a trailer can go is the tires. Trailer tires are only rated to go 65 miles per hour. If you are traveling fast enough that bearings in good condition begin to damage themselves the trailer tires are probably already in the process of failing. Trailer tires are built with a thicker sidewall, to handle vertical loads, that get hot enough to fail when you exceed 65 miles per hour. Going to a larger diameter wheel/tire will not give you the ability to exceed the speed...

• Availability of Replacement Hubs for a Harbor Freight Trailer
  Harbor Freight trailers do not typically use standard hubs or spindles. In most of the situations that we have encountered, we do not carry a hub that uses the same bearings and seal that Harbor Freight uses. The best way to determine if we have a hub that will fit your trailer would be to find the bearing and grease seal part numbers and search for a hub that uses the same bearings and seal. I have attached a photo that shows where the part numbers are located. If you do not have the...

• At What Point Does Heat On Bearings and Hubs Become Excessive
  It looks like you were referring to a previous question regarding excessive heat on the hubs and brakes during travel. If you were getting over 200 degrees that would be a bad sign. But typically if all of the hubs are the same temperature you're good and it's only really an issue if one of the hubs is hotter than others. There are cases where on long trips you'll run 150-160 degrees without blinking an eye on a hot day. You will want to make sure that you're regularly greasing your bearings...
