1999 Trailer Bearings & Seals

[72Shark]

Just replaced my bearings and seals, in case anyone has a 1999 MC single axle trailer: Bearing sizes are - LM67048 for the outer bearing, 25580 for the inner bearing. Seal is a 10-10 seal. Easy, inexpensive, and great peace of mind!

You listed part numbers for the bearings, but what brand are they?

[Table Rocker]

I believe the bearing numbers are common industry numbers that are widely used for very common sizes. I know they work for Timken & Koyo.

The 10-10 seal is a Dexter number that is widely used number for that double lip seal. Timken uses #413470, as does National Seal.

Purchased a bearing kit but dust seals were to big. I see you list 10-10 as the type of seal to purchase but any info where to purchase other than Internet (just incase fitment is an issue) or exact size of this seal? I damaged the old seal when removing it from the hub, so it's hard to tell the size. The outer diameter listed above and the timken part number listed above arent the same outer diameter size..... So?

Depending on whether the trailer was built for a lightweight boat (PS190) or a heavyweight boat (MS200/210), you may have a different axle which takes different bearings/seals.

My post has my inner and outer spindle diameters, and the inner and outer seal OD measurements. Do they match up with yours?

Trailer is holding a lightweight boat (not a 200/210).

5-lug wheels or 6-lug wheels?

Do you need the part number for the smaller seal?

[vrsc]

Correct seal size and part number would be helpful. The above bearing size and seal numbers are not the same and will not work for my trailer

I do have a local napa that i can pick these up at. I called my local MC and honestly, they are clueless to knowing/finding out ANYTHING about my older 1999 boat and trailer. I Just purchased this boat and trailer and it looks as if the bearings had never been changed or repacked. Upon removal, the racers, seal bearings and bearing buddies were all seized on and stuck. The old racers look good, should i be concerned if i dont change them out and just leave them in? My old seal is damaged and correct size can not be determined. Here is what I have 1999 MC SINGLE AXLE
trailer for my 1999 sportstar. 5 lug. The bearing kit that I bought, the bearings were a perfect match, seals would not fit (to big). I also would like to know what bearing buddy to purchase because mine is seized on am I will be damaging it upon removal.

Here is what works so far.

Large bearing L68149
small bearing L44649

Inside bearing 1-3/8
Outside bearing 1-1/16

Thank you for your help
