I found that the center cap from a four wheel drive with manual hubs will cover the hub but still be open to readily check the fluid level with just a light source. Our boat trailer had a cap broken on it and we replaced them with the aluminium bodies. Since it is a boat trailer center cap we do not have a vent in the cap and the axle manufacturer states that the proper fill level is the center of the sight glass.
Yes, I just checked the bearings, lug nuts, air pressure and tread wear on my 5th wheel. Repacked the bearings, torqued the lug nuts and added the right amount of air to each tire before we head out cross country next week. I also ordered an extra spare tire/wheel assembly just in case. Thanks to channels like yours we driveway mechanics keep our toys safe for travel.
Hello! My trailer is a dual wheel with 10,000# axles. The factory 10 ply tire blew today, trailer had about 16k equipment on it when it blew. Trailer is 2 yrs old, with very little use in the two years. The rim was extremely hot. We changed the tire, got to destination, unloaded. Came home. And I felt the brake drums. The side where the tire blew (right side) were very hot. Left side not as hot. All four hubs show oil level is ok. What is causing this heat? I do not believe the brakes are dragging.
Can you explain what the grease fitting is for in the center of the hub? Should you put grease in there and put gear oil in with it or use one or the other or only one of the two? Thanks.
If it has a grease zert, then it is an EZ Lube grease axle. If it has a plastic oil cap, you’ll need to confirm if it has an oil seal or grease seal in the hub to make sure you use the correct lubricant. Thanks for watching!
@@TheTrailerSmith My axles are exactly like yours in this video. They are Dexter 8K oil bath axles with a grease fitting In the center just like yours in the video. I would like to know what that grease fitting is for. Thanks
@@keffjames2747 The grease fitting is for EZ Lube grease axles. Your axle is equipped to handle either oil or grease. The fitting is for occasional grease application if you're running grease in the axle instead of oil. You just have to double check the type of seal you have in the hub. An oil seal will handle grease OR oil, but a grease seal will handle ONLY grease.
@@TheTrailerSmith thanks buddy. My axles are oil filled and this is the first set of these type of axles I have owned and when I took the rubber cap off I was just confused when I saw the grease fitting. Thanks
I have oil on the outside hub of a Dexter 12 k axle. I have still have visible oil in the hub. The oil does not look fresh. How would I diagnose that it is a bad seal? Or could I have perhaps overfilled the oil. I have the valcrum caps. A lot of oil seams to come out the small breathe hole.
Hi there! I would say that the oil cap is likely overfilled if its coming from the vent hole. There are 2 fill lines on the Valcrum caps. Just make sure you refer to the fluid level line matches with the part number for the cap you are using. Hope this helps! Thanks for watching the channel!
