view full answer... - Potential Problems From Damaged Trailer Spindle
- Trailer spindle and bearing tolerances are pretty tight, usually down to a thousandth of an inch. Use of emery cloth on a spindle to remove scoring damage might remove enough material to affect the fit of the replacement bearing. You can be off the original dimension by perhaps 1/1000th of an inch but not much more than that.
If you have a precision caliper that can read to 1/1000th of an inch you can check that repaired spindle's diameter where the bearings ride (and use another undamaged...
view full answer... - How To Determine The Correct Hub/Drum Assembly Based on Spindle Size
- To determine your spindle size, you can either pull one hub off your trailer and look at the bearing numbers on the face of the inner and the outer bearing, or you can measure the spindle itself.
I've attached an article and a photo to assist. If you measure the spindle, you will want to use a digital caliper like # PTW80157 because the precise measurement in the locations where the bearings sit and where the seal sits will determine the correct spindle size.
Once you have the spindle...

- When I search the Timbren site for # ASR3500S06 the description states the following: 3500lbs Axle-Less trailer suspension with 4? lift and regular spindle arms with brake flange. This matches what we have. The issue is not the spindle location relative to the trailer frame. It is the amount of drop in the spindle.
When I search for # ASR3500S05 on the Timbren site the description reads: 3500lbs Axle-Less trailer suspension with regular spindle arms with brake flange. No measurement given...

- The Dexter Trailer Axle w/ Electric Brakes - 4" Drop - E-Z Lube # 8327812-EB has spindles that drop 4 inches from the center of the trailer axle beam.
What this means is that you get an additional 4 inches of clearance from the center of the beam to the spindle.

- The 2x2 inch square axle is likely 3,500 lbs or less capacity. I would need more spindle dimensions or bearing numbers to assist. If you pull a hub and measure at the spindle where the bearings and seal ride using the digital caliper like # PTW80157 I may be able to give you a more specific capacity based on the spindle measurements.

view full answer... - How to Find Replacement Hub for a Trailer Based on Spindle Dimensions
- The bearing numbers you have do not cross reference with anything we offer, but I do have solution for you. You will need to use a micrometer to get exact dimensions of the spindle on your trailer so that I can see if we have a hub that will fit your spindles. Normally with bearing numbers we can find the correct hub, but since you have bearings that we have no info on we have to resort to spindle measuring.
Check out the picture I attached that shows where to measure on the spindle.

- We do have hubs available for a 1" straight spindle in part # AKIHUB-440-2-EZ-1K. This hub measures 4-1/4" deep so it will run a bit longer than the hub you are looking for. There are a total of 4 hubs that we carry for a 1" straight spindle and all 4 would be identical as far as depth. A lot of these older boat trailers use hubs that are trailer specific, and it may prove very difficult to find.

- There is not really an exact required distance between the inner and outer race on a spindle as the trailer hub will dictate this distance and there can very well be some variances between different trailer hubs. However, I went out to our warehouse and pulled a trailer hub that is fit for the BT8 Spindle part # TRU59FR and measured the distance between the inner and outer races (inside to inside). I found this to be right at 2-1/16" so your trailer hub will need to be very close to this...

- When installing a hub like the # AKIHUB-545-35-K on the # TRU84FR the hub is going to stop where the grease seal sits. If you look at the attached picture below, you will see the measurement marked F which is 6-1/2". This would be the stub length, which is the same as the distance from the end to the back of the hub. If you are talking about the other end, the distance would be the overall spindle length of 11-1/4" minus F, which would be 4-3/4".

- The 1-1/16 measurement is the diameter of where the outer bearing rides on the spindle. There are different capacity spindles that have this same measurement. Ones with a thicker stem, the part welded to the axle, have a higher capacity and that is what is on axle # T3584F-EZ-8974. Each of the spindles is rated for 1,750 pounds for a total of 3500 pounds for the whole axle.
