Which Grease Seal would Fit Dexter 7k Trailer Axle

Question:

Hi I have a 2019 grand design 3350rl with 7000lb dexter model 7658660 axle and am looking for the grease seal. Having trouble finding the part # and would like to get them before taking apart. Thanks

7k Dexter axles are a little annoying as they can have two different seals with only difference being the inner diameter. If the seal has an inner diameter of 2.250 inch you'd want the part # GS-2250DL or if instead you had the spindle diameter as 2.125 inch you'd want the # GS-2125DL.

So the least invasive way to determine what you need will be to pull a hub off and measure the diameter of the spindle where the seal rides. To get an exact figure you'll need a digital caliper like the part # PTW80157.
