Help identify bearings parts

I'm looking to repack the bearings of our TT. I would like to buy in advance some parts like seals, bearings, washer erc.

How can I identify what are the existing parts before I dissemble it?

The only thing that I was able to see, is that I have Dexter 4400 lbs axle.

  • Thank you guys. I will buy some parts in advance and will go to replace just in case it wont fit.
    Are you replacing seals and washers every year or just when needed?
  • OP, use the links provided. Or were you looking for some specific recommendations, since google seems to find what you need very easily)?

    Worst case, but small chance, something is different from what you ordered.
    However I’m sure it’s a common bearing size and you can likely get bearings and seals in stock at most any auto parts store if you have disassembled it.

    Just sayin.
  • I just pull them out clean up. the numbers are on the bearing and seals I use only timken roller bearings. and double lip seals.
  • Hmmm... I've R&R lots of trailer bearings when I hauled for a living and found the hard way axle makers bearing/seals recommendations aren't always whats on the spindle/hub.
    Best bet is pull a hub and check the seal number...then remove all the race/bearing sets and get the numbers from them.
    If your (or others) are handy with dial calipers and outside mics use those to find bearings/seal inside and outside measurements. Then let the bearing store match up the numbers.

    We've had members say they carried a set of bearings/seals for several years and found out later they didn't fit.
