Looking For Pre-Grease Hub Assembly For 2008 Bear Trailer

Updated 04/03/2026 | Published 03/28/2026

Question:

Hey Guys, Im looking for a pre-greased complete hub assemble to carry for my trailer. Seems like too good an idea to pass up. Heres the rub, I cant tell exactly which one to get and I was wondering if you had a database that could tell me easily. It is a 2008 Bear Trailer for my boat. Has a zerk fitting on the end so I assume it is an easy grease model. If yall could point me in the right direction, Id appreciate it. Thanks Bill

Hey William, thanks for reaching out. Yes a spare hub is definitely a good idea. I can certainly point you in the right direction, but there isn't a way to look up your trailer to know exactly what hubs it uses. There isn't a universal database for trailers like there is for motor vehicles. We can still find out what you need though.

The best way to determine exactly what you need is with the casting number on your hub. Idler hubs should have a number cast on the back and we can usually use this to pull up your hub and bearing info. If there is a sticker on your axle that shows the axle weight capacity, that will help to narrow things down too.

If that fails, you'll need to remove a hub and pull the bearings. There will be a number stamped on the edge of each bearing, or you can measure the ID with a micrometer.

I'd also need you to confirm the hub bolt pattern. For a 5-lug hub the best way to measure that is from the center of one lug to the outside edge of an adjacent lug. That will give you the true bolt pattern measurement. Should be 4-1/2" but please confirm.

For example, if your axle is 3,500 lb capacity it will use a standard hub and bearing set. For that I'd recommend the following:

- CE Smith Trailer Idler Hub Assembly w/ Case for 3.5K Axles - 5 on 4-1/2 - Galvanized - Pre-Greased # CE13515

This comes with a pre-greased hub in a convenient carrying case - perfect for carrying a spare.

Get me what info you have and I'm happy to look into it and make sure you get the right thing.

What boat are you hauling?

Thanks Jesse, Have looked for a data plate on the axle but couldn't find one. Will check on the back of the hub. As you might imagine, I don't really want to take it apart to figure this out. Trailer sticker says it's max capacity it 2980 pounds. Bolt pattern is 5 on 4 1/2 The hub you recommended has a different cap. Mine has a rubber fitting the allows access to the zerk. Does it come with both caps? Boat is a 2008 G3 (Bass boat) Does this get us any closer to an answer? Best, Bill

@WilliamR Hey Jesse, The trailer axle has a rated capacity of 3500 according to what I can make out on the sticker. The hub is stamped F0116 on the back.

@WilliamR Ok perfect knowing its 3,500 lbs tells us exactly what you need. Those use a standard bearing combination. The # CE13515 hub I mentioned above will work great. It comes with a standard grease cap but if you want an easy-lube cap (with rubber fitting) we have those as part # DC200L-DCRP.
