To replace your NOK AD2527E seal you can use # 168233. It has an inner diameter of 1.688 inches and an outer diameter of 2.332 inches. Based on what I could find on the NOK AD2527E the inner diameter is the same and the outer diameter is 2.328 inches. So it will be a slightly tight fit but no other seal is even close.

On the rear grease seal there’s a spring on the inside of the seal.. how important is this spring.. and can the seal be used without it..thanks

I believe you're talking about the coiled internal spring on your seal. This is used to basically create a tight seal around the spindle to ensure it stays where it's supposed to. Did your spring break off? The seal might not hold as tight to the spindle without it (and thus lead to leaking and lubrication issues down the line) so I don't recommend continuing to use it. I think it's time for a replacement.

The Grease Seal part #168233 has a double lip so it can be used on a boat trailer and be submersed under water, yes. This is also the correct replacement for the NOK AD2527E Grease Seal that you have now.

So the Atwood 83000, 83005, 83010 brake actuators are obsolete, and Atwood is no longer in business so there isn't a replacement master cylinder. You'll need to replace the whole actuator, and for one like the Atwood with the same 8,000 lb…

We don't offer an 8500 lb rated surge coupler, but we might have options that would work for you. If the GVWR (weight of trailer plug boat) is 8000 lbs or less, I'd recommend the Demco item #DM8669113 if your trailer has disc brakes or item…
