Dexter EZ Lubes, use or not?

My TT has Dexter EZ Lube bearings/axles. The video on their web site show that the bearings can be "re-packed" without removing the wheels/seals/bearings in the traditional manner. However, some folks seem to think this a dangerous practice risking blowing out a seal. I have repacked many bearings over the years but, if I don't need to remove the wheels, just spin them as I pump grease in, this seems like the way to go, that is, follow the manufacturer's recommendations.

Why should I or should I not deviate from the manufacturer's design maintenance recommendations?
  • Age old dispute on here. Some use them and love them. Others feel just the opposite. I use them and never a problem. Just make sure you understand the system and do it correctly if you do.
  • I had them on my last trailer which I had for seven years.
    Once a year I would jack each wheel and pump the grease in until the old grease showed up coming out. As I was doing it I would turn the wheel. About four years after I had the trailer I had them professionally done and the mechanic said they were in perfect condition, and then I continued to use the fittings until I sold the trailer.
    For what it is worth, that trailer made a 15,000 mile round trip to Alaska and back in one year, and in the other years, it probably accrued 3,000 miles each year.

  • Not! Nope, never, not a chance...

    You should periodically remove drum - then inspect brakes, then remove old grease and inspect bearings and then repack by hand using new seals. If you don't, how are you going to know what the condition the bearings, seals and brakes are in? Besides, the EZ lube feature just does not work well. Sometimes the bearings weren't lubed correctly lubed or seals correctly installed at the manufacturer and sometimes dealers add grease via the EZ Lube grease zerk on new trailers and cause problems. The photo below is courtesy anothr forum member and shows what the cheap Chinese bearings can look like. The owner of a local frame & axle shop has one just like it on display on his counter.

    Two out of 3 new TTs we've owned had leaking seals and bearing problems from new and both had grease on the brakes. The second time I discovered there was a problem was at the end of the 2nd season (on current TT) after finding that one bearing was running much warmer than the others. Also found leaking seals and grease on the brake shoes. Although it still had life left on the factory warranty, I ended up installing new US-made Timken bearings and hand packing. The dealer already messed it up once and decided it's better to take care of it myself. EZ Lube is just another sales gimmick like "outdoor showers" and "bumper sewer hose storage" features.

  • I have 'em, don't use 'em. It's a good concept but doesn't work and isn't needed. Repack the old-fashioned way when you feel the need.

    My trailer was two years old when I repacked the bearings. They had plenty of grease on them and I have never used the EZ Lube feature. The other thing is you can blow grease past the inner bearing seal and get it on your brakes. EZ Lube also fills the hub with unnecessary grease. The only time that might be needed is on a boat trailer to displace water entry.

    Frankly, I think trailer bearings get way too much unneeded attention. When did anyone last do the bearings on their truck?

    The only thing I would suggest, if one has the mechanical ability, is to do an initial inspection of the bearings, ensure they've got plenty of grease and that the bearing nut is tightened properly. Put it back together and forget about it.
    If a bearing is bad it's going to fail regardless of the grease.

    Once you're satisfied that all is well, you shouldn't have to mess with your bearings again (or at least for several years).
  • If it's time to repack, it's also time to clean and inspect both the bearings and the brakes.
  • You may do better by searching this site. I'm just curious, in 14 years you haven't seen it mentioned on here?
