Boat Trailer Hub Assembly Change

dudewheresmyplugdudewheresmyplug Posts: 29 Greenhorn

Short update video for the Jon Boat project. The bearings on both sides of the axle were in terrible shape. Not knowing how long they had been this way, instead of new bearing we went with an entire new hub assembly. For $80 and all new hardware, it was a no brainer! As always, any questions feel free to ask in the comments. Hope you guys learn a little something and enjoy!

    You can get a hub with everything you need for about $40 bucks at Northern tool or Harbor Freight or Academy Sports and I got a few on Amazon for about $25 a few times.

    FYI to people.

    You need to pre-load your bearings (adjust) before putting cotter pin in and also oil/grease your lugs.

    I didn't say it was your fault, I said I was blaming you

    Yes it's that easy, I have a spare hub in my truck tool box as well.

    Once a year we loosen grease and re tighten our lugs before going on our annual Keys trip. This year added new dust covers, after I cleaned and re-greased everything.

    3rd year on these hubs and they still look pretty good.

    Thank you for sharing this. It is good that you went for the entire new hub assembly and hardware, instead of changing only bearings. It is always good to check the hardware and replace it on time for safety purpose as well as service your trailer at proper interval.

    with bunk trailers,the wheels are underwater,when the boat's launched.the wheels,bearings are hot,from driving - this is normal.when the trailer is backed into the cool seawater,the water is sucked into the hubs - if any seal leaks are present.this contamination,causes bearing failures. "bearing buddies" are a good thing ! most trailer problems come from lack of maintenance to the wheel bearings... checking hardware on trailers is another important things,often missed.most trailers do not have stainless hardware - non stainless will rust and fail... again,bunk trailers are more prone to this,due to the trailer being in the water,to launch the boat
    can we please stop using the word ISSUE ? it's a PROBLEM

    Anti seize on the lug nuts also stainless steel lug nuts are a big help.
