I’m looking to replace the hubs on my 2003 magic tilt model “als 1928” single axle trailer (for an sv1900). Since I don’t know the history of the trailer, I’d rather replace the entire hub assembly rather than only the bearings.
Anyone know the size so I don’t have to pull it apart first to measure?
I’m assuming 1-1/16 but I need to know if the spindle is tapered or not.

I'd contact Magic Tilt for some help with that assuming it has the original axle, or best to remove the bearings and go to napa with the part numbers on them.

Smart choice to change the entire hub rather than just the bearings. I learned too late that it's much easier to do that and the cost isn't much more to buy a complete hub kit as compared to buying bearings and grease seals, especially if you have to buy a bearing race and seal tool kit to do the job right. I know I'll buy a compete hub kit the next time mine need replacing. The only way to tell for sure if the axle is straight or tapered is to pull a hub. You have to do it any way so why not be sure? If your wheels are over 12", then 5 to 1 says they're tapered. Academy sports sells complete hub kits in a plastic carrying case for $49. Hard to beat that price. Anyone want to buy a bearing race tool?  |

I have a Magic Tilt under my V1900 Bay series. I recall that the spindles are tapered. As other great minds have already shared, take one off, identify exact requirements, purchase 2 complete hub kits and replace both. Do not screw around with trying to beat the races out of your old hubs, seat new ones, pack new bearings, etc. I'm pretty sure the kits Juan mentioned are pre-packed with grease. I carry one in my truck as a spare just in case I fry a bearing and don't feel like waiting for Sea Tow.

I went ahead and took it apart. The reason I was reluctant to do that in the first place is because I wanted to order everything and do it all in one shot but at least now I know exactly what it is.
So in case it helps someone in the future assuming my spindles are stock, here is what I found:
Spindles are #84
Bearings are L44649 (1-1/16) & L68149 (1-3/8)
From Amazon:
CE Smith Trailer Tapered 1-3/8" to 1-1/16" Stud (5 X 4 1/2) Galvanized Trailer Hub Kit (2 @ $35/ea)
CE Smith Trailer Nut 1" Washers & Cotter Pins Spindle ($8.50)
Bearing Buddy Stainless Steel Bearing Protectors (1.980" Diameter) with Auto Check With Bras - Pair ($28)
Star Brite Wheel Bearing Grease - Boat Trailer Marine Grade - 14 oz Grease Gun Cartridge ($12)

Anyone familiar with this nub in between the witness marks on the inner seal? I know that whole area should be perfectly smooth. Both spindles have this but it looks like it’s not in the way of the seal so I’m going to leave it. Almost looks like a little ball bearing pressed into the spindles. I can’t find anything about this anywhere.  |

That's interesting. Is there a corresponding depression in the rim of the seal? It looks like the little ball that one would find on a ratchet that you'd snap a socket onto. Maybe it keeps the seal from moving.

That’s exactly what it looks like. I even tried pressing it in to see if it had a spring under it like a ratchet. It does not.
The seal has a depression in the middle, so I guess this is fine. You’re probably right about it keeping the seal from moving.

Strange. First time I've seen one of those. If you figure out why it's there, let us know.

I sent the photo to magic tilt and they said it’s weld splatter and a hammer and chisel will knock it off. What are the odds I got that on both spindles in the same spot?

No kidding? I was so hoping there was a more exotic explanation. Oh well, I guess same welder, same splatter. I’d still buy a Lotto ticket.
Thanks for follow up.

I was contemplating doing the same thing at the beginning of this year. Ended up dropping the boat and trailer off at The Trailer Connection. $65 per wheel, new hubs and bearings. Saved me a day of aggravation.
