How to Tell if Trailer has a BT8 or BTR Spindle Installed  

The BTR and BT8 denotations refer to the spindle, not the trailer hub. The difference between a BTR and BT8 spindle is that the BTR spindle uses a 1.063" diameter L44649 bearing and the BT8 spindle uses a 0.99" diameter L44643…

BTR and BT8 are the reference numbers for a standard trailer spindle size. When picking out a hub for a trailer you have to make sure that the hub is designed to fit the spindle. What you will need to do is measure spindles on your trailer where…

Hey Les, thanks for the info you mentioned from your old hub. Based on that the part #AKIHUB-545-2-G-EZ-2K would work great as a replacement. This is also galvanized which means it will do a great job fighting corrosion as well.

You will want either the CE Smith Galvanized #CE13315 or Black #CE13311 idler hub assemblies. These both have the 1-1/16" ID bearings #L44649 and include grease seals for your 1-1/4" spindle diameter.

The difference between an load range C and load range D tire in the same size is the capacity and psi rating. The two tires will still have the same dimensions and fit on the same wheel. The D rated tire has a higher capacity. For a ST175/80D13 like…

For a replacement hub to fit on a spindle it must use the same bearings as the original hub. Sometimes bargain trailers use odd sizes of bearings that are not readily available and so it can be tough to find suitable hubs, but you can check by…

We've had customers with your Dico 45263 hub in the past get us their bearing numbers so we know that for a replacement with the wheel bolt pattern you need you could use the #AKIHUB-545-2-G-EZ-2K and you'd be set.

The difference between the two trailer sizes you referenced is that the 5.30-12 will be about 1-1/2 inches taller than the 4.80-12 and would have more capacity. As long as your trailer has the clearance for a slightly taller and wider tire a 5.30-12…

You can add larger wheels and tires to a trailer as long as you have enough room for the larger size. The main clearance issues we find when putting larger tires and wheels on a trailer is from the top of the tire to the fender and from the inside…

The #84 spindle is just a common way to identify the spindle dimensions typically used for 3,500 lb axles. So instead of listing out the parts, people can just say they have #84 spindles and it's easier to know what fits it. The CE Smith Trailer…

With the info you listed I was able to determine that you have a 5 lug 2,000 lb capacity hub no so for a replacement you would want the #AKIHUB-545-2-G-EZ-2K that you referernced. This comes with bearings and an ez lube cap as well.

If your customers are blowing out their grease seals most likely that is due to too much grease being pushed into the hub. Using a Bearing Buddy Seal like the part #BB60005 would give you a grease seal that is more reinforced than a standard one, but…
