E-Z Lube-Compatible Hub for Simple Lubrication

The grease cap on this hub-and-drum assembly is specially designed to work with your Dexter E-Z Lube axle to make lubricating bearings quick and easy. Just remove the plug on the grease cap, attach a grease gun to the zerk fitting on the end of the spindle, and inject the grease. It will flow easily to both inner and outer bearings. Not only does this make lubricating the bearings easy, but it also helps to prevent corrosion of the hub. This is because you can lubricate the bearings without the mess of taking apart the entire assembly.


Determining the Bolt Pattern

The first number in the bolt pattern is the number of bolt holes. The second number denotes the diameter, in inches, of the circle on which the bolt holes sit.


Bolt Pattern - Even

On wheels with an even number of bolt holes, measure from the center of one bolt hole to the center of the hole directly across from it. (Example: "8 on 6-1/2" means 8 bolt holes with 6-1/2" from the center of one hole to the center of another on the opposite side.)


Bolt Pattern - Odd

To determine the bolt-circle diameter on wheels with an odd number of bolt holes, measure from the center of any bolt hole to the point halfway between the two bolt holes directly across from the first. (Example: "5 on 4-1/2" means 5 bolt holes with 4-1/2" measured to a point halfway between the opposite bolt holes.)


Bolt Pattern Side

Measuring the distance (D) from the center of one bolt hole on the wheel to the center of a bolt hole right next to it can also help to determine the bolt pattern.

  • If D = 2-5/8", then the bolt pattern is 5 on 4-1/2"
  • If D = 2-3/4", then the bolt pattern is 5 on 4-3/4"
  • If D = 3", then the bolt pattern is 5 on 5"
  • If D = 3-1/4", then the bolt pattern is 5 on 5-1/2"

Essentially plug and play for my previous hubs. Great quality and fit. Would purchase again.

Not even 2 years after install all rusty. Electric brake pin broke due to rust.
Impossible To remove 4 bolt holding connector due To rust. I do not recommend




by:

Well after receiving 2 different hubs and unfortunately of course installed the correct one first about 45 minutes or less. Perfect fit and finish. etrailer took care of the wrong hub and when i received it took around 30 minutes to install that side. If you have general knowledge and just a bit of mechanic skill you can do it. Added brakes to my 2008 pop up camper, have driven this over 8000 miles (or more) now and has worked flawlessly. Highly recommend.




by:

Needed electric brakes on my Scamper pop up camper 1997, to tow with my Subaru (needs brakes over 1 000 lbs). These fit perfectly. Easy to install and a breeze when you drive.


Comments
Thank you for asking. I am very happy with my purchase. Worked great last summer and I look forward to taking the road again with my Skamper camper and feeling secure. Have a great summer

I purchased a pair of these to replace the hubs on my 2001 Jayco popup camper w/Dexter axle. They arrived quickly and included everything but the grease. The races are already installed, which is great. These are EZ lube hubs, but the only difference I could see is the EZ lube dust cap and a different hub seal. I installed these on non-EZ lube spindles and used the bearing buddies I already had. eTrailer was great in addressing the one question I had, the price was great, and I got free shipping with my order over $150.




by:

New hubs were shipped immediately after ordering and arrived the next day. They fit my 2004 Viking Epic 1706 perfectly. I was able to change them out in about one hour and get on the road to Florida. I re-torqued the lug nuts and checked the hub temperature at every gas fill up and they never got warmer than the tires. Drove 1000 miles in two days with no issues. Thank you etrailer for quality parts at great prices and excellent customer service.




by:

This is a great product for a great price. Perfect fit and easy assembly for the inexperienced. I put 5000 miles on this set immediately after install and it worked flawless with brake control.
Highly recommend etrailer products and great service.

Great quality dexter product. Was a quick and easy replacement for the worn drum on my tent trailer with a 3000lb dexter axle.




by:

I ordered two of these. They arrived quickly and works perfectly.


Comments
Ive had these brakes for a year now. I am still pleased with them. Although I did have trouble with the Drivers side unit at first. I could not eliminate a squeak when applying the brakes. eTrailer worked with me to resolve the problem. They sent me a total one side replacement. I recently completed a 300 miles trip with the camper and the brakes worked perfectly. No more squeak.

  • Replacement Brake Drum for a 1998 StarCraft 2408 Pop Up Trailer
    When trying to find the correct drum brakes, a measurement of the inside drum diameter and the depth of the drum will be needed. See attached picture. The drum that you referenced, # 8-173-16UC3, measures 7 inches in diameter and 1-3/4 inches deep. Also this drum will have a 4 on 4 bolt pattern. If your drum has this measurement and your current shoes measures 1-1/4 inches wide, then this will be the correct part and work it well for your pop up camper. I have also attached an article...

  • Can Electric Trailer Brakes be Added to a Harbor Freight Kit Trailer
    Neither of those Harbor Freight trailers has brake mounting flanges on the spindles. To add electric brakes you would have to have brake mounting flanges welded on. This is a precision job that requires a special jig and someone with experience in welding on flanges. I have included a link to the flanges we carry to the right. You would also need to replace the idler hubs on the trailer(s) with hub and drum assemblies. The problem with that is the Harbor Freight trailers use uncommon bearings...

  • Replacement Axle for Harbor Freight Trailer
    In order to find a replacement axle for your Harbor Freight trailer you will need to take some measurements to determine the correct axle length. The most important measurement is the distance from hub face to hub face. Additionally, you can measure the spring center distance. When replacing your trailer's axle, you should be able to figure out which type you need by determining your trailer's capacity, the bolt pattern of your wheels, the brake type and these measurements.

You can find the bearing kit as part # BK1-150 on our site. For a replacement hub we have the part # 8-91-05UC1 for a standard spindle or part # 8-91-05UC1-EZ for E-Z Lube spindles.

  • Diameter Of Hub On Trailer Hub And Drums With 4 On 4 Bolt Pattern
    I went to the warehouse and measured the hub on both the # 8-173-16UC3-EZ and the # 8-276-5 hub. The outside hub measurement for the 8-173-16UC3-EZ is 2.47-inches. The outside diameter of the hub for the # 8-276-5 hub measures 2.06 inches. Both of these hub assemblies have a 4 on 4-inch bolt pattern so I have attached a link to the tire/wheel combos with 4 on 4 bolt patterns you can check out.

    If you do indeed have a 4 on 5 inch bolt pattern we have one hub that matches that. For that you would need the part # AH15450ECOMP. There is a better chance that you have a 4 on 4 inch bolt pattern as that is the most common 4 bolt mounting pattern. I attached a help article on determining bolt patterns as well.

  • Brake Drum for a Reliable 2,700 Pound Trailer Axle
    If the spindles on your Reliable 2,700 pound axle are straight (same diameter in both bearing locations) then that indicates that it uses L44649 inner and outer bearings but if the spindles are tapered (inner bearing surface diameter is larger than the outer bearing surface diameter) then it will use L68111 for the inner bearing and L44649 for the outer. If you pull a hub off and find that both bearings are L44649 you can use # AKHD-545-2-EZ-2K if there are grease fittings at the ends...

  • 4-on-4 Bolt Pattern Hub/Drum for Use on 2K-Rated Axle
    Matching up new hub/drum assemblies to your Dexter P-11 axle just requires matching up the bearings used in the original hubs and confirming the axle weight rating. New hubs have to use the same bearings in order to fit on your spindles and your new pair of hubs need to be rated for the capacity of your axle. Usually a plate or sticker on the axle itself (or the trailer) will tell you this. I see that you selected 7-inch brake assemblies for a 2K axle. For 4-bolt hub/drums you can use...
