Robert, thanks for providing the trailer information. For the Dexter 5,200 lb axles on your 2021 Grand Design Reflection 310RLS, the correct grease seal is part # 10-36. This seal has a 2.25 inch inner diameter and is commonly paired with the bearing combination of # LM67048 for the outer bearing and # 25580 for the inner bearing.
If you're planning on servicing the bearings while you have everything apart, you might also consider the complete bearing kit part # BK3-300. It includes the bearings, races, grease seal, cotter pin, and tang washer, which can be handy if you find any wear during inspection.
Since you're repacking the bearings, you'll also want a quality wheel bearing grease. I typically recommend the LubriMatic Prime Guard High Temperature Wheel Bearing Grease part # L11380. It's a high-temperature red grease that works great for trailer hubs and is what we commonly use here. A bearing packer like part # PTW1218 can make the job a little cleaner and easier, although it's definitely not required.
I know getting the right seal the first time is important because nobody wants to deal with grease on the brakes or have to tear everything back apart. With the Dexter 5,200 lb axle setup, the 10-36 seal is the correct match. Where do you love taking your Reflection 310RLS most, the mountains, the lakes, or those quiet campground getaways?
