Ask the Experts about this TruRyde Trailer Spindles

• Recommended Spindle, Idler Hub, Wheels and Tires For Homemade Cart Trailer Off Road Use Only
  We have the #42 Spindle # TRU57FR that you can weld to your trailer. It is a 2-1/4" round stub as we do not have any square stub spindles that are rated for over 2,500lbs per spindle. With these spindles you can use the Trailer Idler Hub Assembly # AKIHUB-655-6-K since you do not need a braking hub. The hub is 6 on 5-1/2" as the 5 lug wheels are not strong enough for the 10,000lb capacity that you are needing. The Taskmaster ST225/75D15 Bias Trailer Tire with 15" White Mod Wheel...

• Compatibility of Redline Replacement Axle Spindles with Dexter Hubs
  TruRyde Spindles are indeed compatible with Dexter hubs, if the spindle is matched properly with the bearings your hub uses. To find the correct spindle, match the inside diameter of your inner bearing, outer bearing and grease seal to the dimensions of the bearing surface of the spindle, as shown in the photo I provided. You'll also need to match the weight capacity of the spindle with that of the axle.

• How to Determine Correct Replacement Spindle Based on Measurements
  I can tell you how to determine the correct spindle based on your measurements, and what you will need is a digital caliper such as # 301-17068, though the first thing you need to know is the weight rating of your trailer axle. From there, what you need to do is measure your spindle to the thousandths of an inch where the bearings and grease seal ride, along with the length and diameter of your stub. For example, the accompanying diagram shows the measurements of the #42 Spindle for...

• Will TruRyde Spindle TRU57FR Fit Dexter Trailer Hub Assembly 42865-KIT
  The TruRyde #42 Spindle # TRU57FR is compatible with the Dexter Trailer Hub Assembly # 42865-KIT.

• 5-on-4-1/2-Bolt Pattern Hub for Use on Redline 2-1/4-Inch Spindle # TRU57FR
  Selection of a compatible hub for use on the Spindle # TRU57FR requires matching up the bearing set that fits this spindle (25580 inner bearing and LM67048 outer bearing) to the bearings in the hub.

• Trailer Spindle, Hub and Drum, and Electric Brakes for a Fabricated Utility Reel Trailer
  Spindle # TRU37FR is the highest capacity spindle we have at 2600 pounds. It is a 2-1/4 inch round stub. The part of the stub before the brake mounting flange is 3 inches but the length including the part on the other side of the flange before it tapers down to a smaller diameter would be 6 inches. Then you could use hub and drum assembly # 8-219-4UC3-EZ which does fit the spindle and it has an 8 on 6-1/2 bolt pattern. For electric brakes you can use # 23-105 for the left and # 23-106...

• Which Trailer Hub Works With the #42 TruRyde Spindle Part # TRU57FR

• How to Remove a Hub From a Trailer Spindle
  To remove a hub from an axle, you will need to first remove the grease cap on the end of the hub. This will expose the end of the spindle. Once at this point, you will need to see if you have an EZ-Lube spindle, like # TRU77FR, or a standard spindle, like # TRU57FR. If you have the standard spindle, there will be a castle nut threaded onto the end of said spindle that is locking a fairly large washer in place. This will be locked in place by a cotter pin, like # 165649. These will all...
