    Putting the trailer bearings back together.... last step- just pop the cap on the hub. Thats the easy part... right?
    WRONG!!!!
    I have never had good luck getting these dang things on. Previously installed ones seem a little easier.. but brand new ones?? Forget about it! I always struggle and end up beating the heck of of them. So much for new ones.
    What tips or tricks do you have? No, not " use a piece of wood to avoid denting them"...

    Keep it even. Don't try to drive it in all at once. Gentle taps. I prefer a rubber mallet to a steel hammer.

    That seems possible i guess. This time in particular these are new hubs from etrailer and new bearing kits (w/ caps) from etrailer.
    It is very frustrating!
    Maybe Ill contact them and ask their advice.
    Oh, btw- I'm not exactly a stranger to mechanical things being a maintenance mechanic and electrician for over 20 yrs now (that on top of a childhood of crankin' on broken lawnmowers, bikes and go carts) so yeah... I'm pretty good ;)

    I have an old socket that just fits the lip I place this over the cap and tap it in with a rubber hammer it all goes on evenly this way

    They never look as nice after I repack the bearings!

    Find a piece of pipe that fits on the flange, weld a round plate to the other end for pounding. Sometimes it takes pliers to just slightly give the lip a little extra bend in.

    Yep ok.. this is that i was thinking. Monday I will make an install tool out of pipe as described above.. also while at the lathe I will attempt to roll a slight inward bevel on the cap. Those two things should ease my troubles... oh course I had to bash one new cap in before using my head here (and yours!) .

    Tip I read for bearing buddies was put them in the freezer, get the metal cold to shrink it up a little. Might be worth trying for the regular caps as well.

    I used a 2" pipe nipple to put the old ones back on. The new ones just would not go.

    I've had that problem... and also the exact opposite problem, where the bearing caps fall right off after you put them on (I have had to bend them slightly out-of-round so that they stay on). I don't think the caps and hubs are manufactured with consistent tolerances.

    I will slightly bevel the edge on a grinder. It seems like the coating on them make them just a tad thicker in diameter, causing frustration. 15 seconds on a grinder and all is good.

    My advice: keep the old ones lol... new ones never seem to fit... even when they're the "right" size!

    I ended up chucking them in the lathe(gently of course!) And using a file to bevel the edge. Then they went in relatively easy.

    Make sure you wash them out after grinding. You don't want to make a lapping compound out of the grit mixed with grease.
