Question:

I have a 10K equipment trailer that has two Dexter axles photo attached that are marked as follows: PR-FF SEC PF 6KPR GG SEC GG 12X2DX0 36-89 The backing plate is bolted, not welded, to the axle photo attached. The trailer has 14.5x8 Load Range F 12 ply tires on it rated at 2790 Lbs. The rims that the tires are mounted on are stamped “Made in USA DOT-T 14.5x6 MH Light. 3000 LBS Capacity MH Tire Use Only”. The rims mount to the hub with 5 bolt tab clips. I have been told that the tabbed rims are no longer legal. I don’t know if that’s correct or not. Do you offer a replacement hub/drum that will fit these Dexter axles and allow me to mount a standard 15 inch steel trailer rim? Thank you for your assistance

Thank you for reaching out!

It looks like your Dexter Axle uses the 5 Spoke Utility Hub and Drum Assembly # 8-174-5UC3 so to replace that and your brakes you need the Easy Grease Trailer Hub and Drum Assembly # AKHD-655-6-EZ-K as well as the 12" Self-Adjusting Electric Brakes # TRU96FR. These will be exact fits for your system but the hub and drum kit comes with a slightly larger grease seal so you need the Replacement Grease Seal Set # RG06-090 for each axle on your trailer. Your older brakes should be 12" x 2" so they will work with the newer hub and drum kit, but from the pictures you sent in it would be a good idea to replace the brakes as well.

Your 8-14.5 MH tires have an overall diameter of 27.7" so for a suitable replacement tire with a similar weight capacity I recommend going with the Karrier ST225/75R15 Radial Tire with 15" White Spoke Wheel # AM32680. This has a Load Range of E (2,830 lbs at 80 psi) and a max speed rating of 81 mph.

I don't know if the 5-Spoke Utility-style rim is illegal, but it's definitely harder to come by so I always recommend swapping trailer equipment to something that's easier to find if you need to replace something.

Attached are some review and installation videos for you to check out.

do you need to change the brakes?

@Josh If the brakes are worn out, then yes. Check to make sure that the brake assembly is in good working order and that your brake shoes aren't worn down. If they are, then it's best practice to change both brakes on a given axle.

@JonG no the brakes are new. On a different note I have two 7000lb axels on mine and would like to keep the capacity. So what hub would you recommend a 8 on 6.5 bolt pattern

@Josh The Trailer Hub and Drum Assembly # AKHD-865-7-1-K could very well work but you'll want to confirm that these fit with your spindle. Here are the dimensions for the following parts: - Inner Bearing 1.75" - Outer Bearing 1.25" - Grease Seal 2.25"
