Recommended Replacement Bearings For 2020 Grand Design Momentum With Tandem Dexter 7000lb Axles  

Question:

I would like to purchase axle bearing seals for a 2020 Grand Design Momentum 351m with dual 7 k Dexter axles. Electric drum brakes. What seal do I need?

Expert Reply:

The majority of 7000lb axles like the Dexter 7000lb axles you have on your 2020 Grand Design Momentum 351M use inner bearing # 25580 and outer bearing # 14125A but I recommend double checking this as there are still some odd bearing combination options.

The easiest way to confirm your bearing combination is by removing one of your hubs and looking for the bearing numbers stamped on the face of each bearing as shown in the included picture of the # L44649.

If you do have the # 25580 and # 14125A I recommend the Bearing Kit, 14125A/ 25580 Bearings, 10-36 Seal # BK3-200 which will include bearings, races, and a new grease seal.

I included a video of the # BK3-200 for you to take a look at.
