• Grease Caps For Hubs on Lippert 7,000 lb Axles
  We have grease caps for a 7,000 lb Lippert axle (including torsion axles), though I do need to say that grease caps are are drive-in, and oil caps are screw-in. I verified with Lippert what the correct grease cap is for their 7,000 lb axle, which is the following: - Standard Grease Cap: Trailer Hub Grease Cap # RG04-100

• Adding Disc brakes To A Fifth Wheel With 7K Axles With 6 on 5-1/2" Bolt Pattern
  We do recommend switching over to an 8 on 6-1/2" bolt pattern when adding disc brakes to a 7K axle. All of the 6 lug disc brake kits are going to be rated for 6K and under. For a full disc brake conversion I recommend the Hydrastar Conversion Kit # HSE7K-T1. This is a complete kit, so you get everything you will need to convert your 7K electric brake axles over to disc. This uses the # 25580 and # 14125A bearings which are basically standard for 7K axles. The only thing you will need...

• Replacement Bearing Cover Options for Bri-Mar Dump Trailer
  You will need one of two sizes depending on the axle capacity of your Bri-Mar dump trailer. If you have 7,000 lbs or 8,000 lbs axles, then you will need part # 21-43-1 and # DC-RP if you have EZ Lube spindles (grease zerk on the end) or you can use part # RG04-100 if you have standard spindles. If you have 5,200 lbs or 6,000 lbs axles, then you will want part # RG04-080 if you have EZ Lube spindles or part # RG04-060 if you have standard spindles.

• Replacement 2.72 Inch Diameter Grease Seal for a Trailer Hub
  It sounds like you need a grease cap for your trailer hub. If this is the case then I recommend using part # RG04-120 if you have E-Z lube axles or part # RG04-100 if you do not. These caps are both press-in but if you have trouble then I recommend placing a rag over the cap and tapping it with a hammer very gently.

• If a Wheel Has a Hub Cap is a Grease Cap Needed Still
  You still need a grease cap if your wheel has a hub cap. A hub cap is purely a decorative item to make a wheel look nicer. A grease cap actually serves a purpose by holding the grease of the hub in so that it stays lubricated. I attached a page that has all of our grease caps. To pick out one out you will need to measure the pilot hole of your hub.

• Which 6 On 5-1/2 Bolt Pattern Hubs Will Fit A 2008 M1101 HMMWV Trailer?
  From what I could find, your 2008 M1101 HMMWV trailer will use the # 25580 inner bearing, but the outer bearing is proving to me more difficult to locate. It looks like it has a 1.25" inner diameter, which does match two hub and drum assemblies we have. These do use different seals though, so you will need to pull one hub, or both, so see which will be the correct option. I have both options listed below and these do have the needed 6 on 5-1/2 bolt pattern and 12" diameter drum. Trailer...

• Available Grease Caps for Threaded Trailer Hubs With an Inner Bore Diameter of 3-5/8-Inches
  It sounds like you may be looking for Bearing Buddys that will fit your threaded hubs. The standard drive-in grease caps you referenced, part # RG04-100, fit a non-threaded hub bore of 2.72-inches, a good bit smaller than yours. The standard grease cap nearest to your size is part # F001603 which fits a non-threaded hub bore of 3.882-inches. Bearing Buddy grease caps are available in sizes for hubs up to 2.717-inches inner diameter but none will fit your 3-5/8-inch hub bore.

• Wheel Trim Options and Grease Caps for a Vintage Trailer
  A hub cap is going to cover the whole wheel in many cases whereas a grease cap only covers the hub bore so it is much smaller. Think of it as a hub cap covering the whole hub and a grease cap just covering the open end on the hub. A good look for a vintage trailer would be the Americana Baby Moon Trailer Wheel Center Cap, # AM90086. It fits 13 to 15 inch conventional wheels. However, the chrome plated steel may be too much flash for what you are going for. If you want the wheel appearance...
