• Is Broken Zerk Fitting of Trailer EZ Lube Spindle a Problem
  Actually it looks like your spindle had a standard zerk fitting on it at one point and it was possibly removed on purpose or accident. We don't have a way to install a new one. Honestly though you are better off without using this type of EZ lube setup. Repacking the bearings with grease by hand will give you the best results and won't risk you over-greasing the hub and blowing out the grease seal. I have linked a video to the right that shows how to pack trailer bearings. Be sure...

• Can a Trailer Axle be Converted to an EZ Lube Axle by Replacing Spindles
  To upgrade to an EZ lube setup will require you to replace your axle or you could just replace the spindle. For a spindle with a 4 bolt mounting plate you would want the part # TRU74FR as it is an ez lube spindle. For a new hub/drum to fit this you would want the part # AKHD-545-35-EZ-K or for a idler hub part # AKIHUB-545-35-EZ-K. Welding a spindle is not something we recommend most people doing. Most axles have these welded on at the factory with specialized jigs and higher precision...

• How Does The EZ Lube Spindle # TRU74FR Work On A Boat Trailer
  On the EZ Lube Spindle # TRU74FR you do not need a grease fitting for the hole on the inside end of the spindle. This is an EZ lube spindle which is designed to allow you to put grease onto the bearings by using the zerk fitting on the threaded end of the spindle. You will not want to block the hole that is on the inside end of the spindle. When the hub is installed on the EZ lube spindle it will form a cavity around the wheel bearings and when you pump grease into the spindle through...

• Could Zerk Fitting be Added to Trailer Spindle to Make it an EZ Lube Spindle
  EZ lube spindles are more than just a zerk fitting attached to the end of the spindle. There would need to be a hole in the spindle between where the bearings ride for the grease would then fill the hub by. To be perfectly honest using EZ lube spindles or Bearing Buddies typically causes people to over fill their hubs and blow out the grease seal so you're better off packing the hubs by hand. I attached a link to a bearing packing video for you to check out as well.

• Benefit of E-Z Lube Spindles for Easier Wheel Bearing Lubrication
  Using a grease gun on the zerk fitting of an E-Z Lube spindle like # TRU74FR can make it all too easy to over-fill the hub grease level. Care should be taken to avoid the risk of blowing out the inside grease seal. For such applications a double-lip seal is recommended since it will be less likely to suffer failure and leak grease everywhere. Using E-Z Lube spindles/grease caps makes for an easier time topping off the wheel bearing grease level. But the same routine maintenance is still...

• Replacement Axle Recommendation for Yachtclub Snowmobile Trailer Rated for 1,880 Pounds
  For your snowmobile trailer I recommend going with a Timbren Axle-Less system such as # ASR2000S01. I have included a link to all the options rated for 2,000 pounds. The benefit is that you won't have an axle beam to rust and you still get the rubber, torsion-style suspension.

• Greasing Trailer Axle Spindle Where Zerk Fitting Broke Off
  What I would recommend you do is extract as much of the old zerk fitting as you can and then going forward grease that hub by hand and you'll be totally fine if not better off than using the grease fittings. It's pretty easy to overfill EZ lube spindles and blow out the grease seal of the hub so if you grease the hubs by hand you'll avoid that and be in good shape.

• Troubleshooting Slight Amount of Grease Leaking from E-Z Lube Spindle
  Any grease on the back of the wheel could be from the grease working its way out from having slightly too much or it could be from a grease cap or grease seal that is not fitting properly. The grease cap and seal should be keeping any excessive grease off the wheel unless the parts are failing. I recommend pulling the rubber plug to see if there is grease inside and if so just clean the wheel and keep your eye on it for more. If it keeps happening, something is not working correctly...
