Thank you for reaching out!

What is the weight rating of your axle? Unless it's a really old axle I should be able to make a recommendation based off of that. The Dexter Axle part number you sent in normally doesn't pull anything up on their system (although I'm not sure why) so I would need the serial number and/or a photo of the sticker in the middle of the axle for me to get any info from Dexter Axle.

Thank you for the photo, this definitely helps out. Since you have a 3,500 lb axle you need a grease seal that has a 1.719" ID and 2.565" OD. For a single seal we have this as part # 58846 but if you need 2 of these you want to go with part # RG06-050 instead. Attached is an installation of this for you to check out.

The inner diameter of a grease seal can be hard to get an exact dimension. The best way to get this info is to actually measure the outer diameter of the spindle where the grease seal rides. The grease seal part number #168255TB that you referenced…

Grease seal set #RG06-050 is what you will need. These are double lip seals, just like what you have (the spring indicates that) and the dimensions are all the same including the 1/2 inch width.

Answer 5

The TruRyde #RG06-050 double lip grease seal is indeed wire spring reinforced, as you can see in the photo I've provided. The wire spring actually looks similar to a guitar string. Although double lip seals will work for any application, we…

Answer 6

I checked with Lippert and could not find any information on NV304664. Do you know the capacity of the axle? If it is a 7,000 pound axle then the likely inner bearing is #25580 and the outer bearing is #14125A. If a 2-1/4 inch seal diameter is needed…

That is a Timken seal with the part number 171255TC, so you can use the Grease Seal - Double Lip - ID 1.719" / OD 2.565" - for 3,500-lb Axles - Qty 1 #58846 as the replacement or you can get a pair with part #RG06-050.

Answer 9

From what I have found, the GVWR of your 2020 Grand Design Imagine XLS 22RBE is 6,995 lbs. Based on that information, you more than likely have 3,500 lb axles. The most common grease seal for a 3,500 lb axle is the #58846 with a 1.719" inner…

Answer 10

On grease seals the TB means a low pressure, double lip seal with a spring and the VB means a non-pressure, single lip seal without a spring. The seal you will need for the part #171255TB is the TruRyde Grease Seals-Double Lip, part #RG06-050. This…
