Question:

I have a boat trailer that has .748” straight spindles and 4 on 4 hubs that measure 1.77” inner diameter where the race sits. What is the replacement hub?

The bearing numbers that you provided LM11949 are an unique agricultural bearing that we do not offer. You will have to replace the whole axle to get the hub and drums to work that I mentioned above.

The Trailer Idler Hub Assembly for 2,000-lb Axles # AKIHUB-440-2-2K is the correct replacement hub for you, if your inner and outer bearings are the same size and have the number # L44649 on them.

This hub assembly is for a 2,000 pound axle that has an inner and outer bearing # L44649 which has an inner diameter of 1.63 inches.

This idler hub is pre-greased and is easy to install, there is no need to pack the bearings. The hub has a sturdy iron construction and has a zinc-enriched paint finish. It has a weight capacity of 1,000 pounds and fits wheels between 8 inches to 14 inches.
