Hey Bill, thanks for reaching out!
Your 2022 Grand Design Momentum 21G axle models the 5,200 lb axles from Dexter so you'll either need the kit # RG06-090 with a 2.125" ID or the kit # RG06-070 with a 2.250" ID. I tried reaching out to Dexter Axle for an exact seal for your axle but they have yet to respond to me.
