Determining if 2,000 lb Axle Needs 1-1/4 inch or 1-3/8 inch BT8 Spindle  

The special trailer (ST) tires will have a maximum speed rating of 65 miles per hour, unless stated otherwise on the tire. It is not recommended to run a trailer tire at a higher speed than 65 miles per hour due to the heat buildup that will occur…

The amount of bow that's put into trailer axles like the #7359765 is based on about how much a trailer is typically going to weigh that has a 3,500 lb capacity. So there's a bit of approximation and obviously it can't be totally perfect…

You have a 2-3/8 inch O.D. pipe so you might want to look at #84 Spindle, #TRU84FR, which has a 2 inch O.D. at the weld point and has a 1750 lb. capacity, so two spindles will give that axle 3,500 lb capacity. The #42 Spindle, TRU57FR which has a…

I checked with Trudyde, and I was able to find out that the bar stock material used to make the spindle is hot rolled SAE 1045 steel, which allows the spindle to harden to an extent. The spindle needs to retain a slight amount of flex to retain its…

The BTR style of spindle like the part #TRU44FR has bearing surfaces that are both 1.06 inch in diameter. That's probably the closest we have to a straight spindle in the capacity of 2,200 lbs like you want. 1.00 inch for the threaded portion…

Based on your hub having two of the L44649 bearings that would mean you need a BTR spindle like the part #TRU44FR. To replace a spindle, the old one would need to be cut off, and the new one welded into place. This is NOT a job for the…

The spindle you are looking for is a BTR spindle like the part #TRU44FR.

What you describe isn't normal. Trailer axles are manufactured with a bow or crown in them, a slight arc with the high side on the top of the axle. When the trailer is loaded, the axle will straighten out so the tires make even contact with the…

Trailer spindles are welded directly to the axle so to remove one it just needs to be cut off completely using a torch or saw. Then to replace the spindle such as with the EZ Lube #TRU37FR that you were looking at it's extremely important that it…

The TruRyde Spindle #TRU94FR that you referenced has a 1-1/4-inch diameter stub. This spindle will fit an axle beam (pipe) with a 1-1/4-inch inner diameter. While you can certainly fabricate your own axle to go on your homemade trailer, assuming you…

Ideally you can get the measurement of your axle by using a precision instrument like a digital caliper similar to Item #PTW80157. There is also often a sticker or a tag on your trailer axle that tells you the weight capacity of your axle which can…

In order to determine the torque rating for the lug nuts on your trailer you will need to know check out the chart I attached that shows all of the torque specs for all the trailer lugs available based on stud size, wheel material and wheel size.
