Question:

Hello, Im trying to find the correct replacement bearings for my 5th wheel. From the sticker on the axle: Dexter 118179, rated at 6,000 lbs. The axle serial number is 132220344021, PO KE00436611. Thanks!

Hi Roger!

I contacted Dexter with your axle information and you will need the # 25580 inner bearing and # 14125A outer bearing. If you want the races as well, you will need the # 25520 and # 14276 respectively. The seal will be the Double Lip - 2.250" ID - 3.376" OD # GS-2250DL. These are all our branded parts, but if you wanted American made Timken ones, you will want the following parts:

Inner Bearing: # TMK44FR - Race: # TMK76FR
Outer Bearing: # TMK54FR - Race: # TMK96FR
Seal: # TMK98ZR

Any of these options will work, but ours are a lot less expensive. What kind of 5th wheel do you have?

Thanks so much, Lazer! This was actually for a friend, and I have passed this info on to him. I'm happy to say he is going to be an e-trailer customer. Regards, Roger K
