Question:

I have a 2 Dexter 7k axles with part number 130087 on my 2017 Grand Design 310gk. I am looking for information and part numbers on the inner wheel hub seal that holds on the inner bearing. I found a Lippert seal with part number 333693 on Amazon and wasnt sure if it is a comparable part. Any assistance would be much appreciated Thank you

The interesting thing about Dexter 7k axles is that they could come with two different grease seals with the only difference being the inner diameter of the seal.

If the inner diameter is 2.25 inch you'd want the part # 10-63 or if it's 2.125 you'd want # 21325.

Easiest way to take this measurement is to pull a hub and measure the spindle where the seal rides.
