Today I noticed that one of the grease caps on our 2020 21C is missing. Does anybody happen to know the proper replacement size? I assume that they are available at auto parts stores.
Easiest thing to do is remove the other one and take it with you. Or caliper the hub ID with a small Digital caliper.
You might find this info on a dexter website for 3500 lb axle.
Hope this helps
