Question Rear Axle Seal for 2019 Coachmen

Hi! Long time lurker, first time posting Will be having the axle seals replaced by my brother in law this week, along with some other general maintenance. I was wanting to purchase the new seals now to be ready. Without dismantling anything, is there a way to find what size I need? Google hasn't been much help, my RV dealership here is closed for the day. I have a 2019 Coachmen Freedom Express Liberty Edition 320BHDSLE. ST225/75R15D tires. Anyone know off-hand from experience before I head out? Thanks!

ETA: Originally stated rear axle seals, but changed it to axle seals as I believe he will be replacing all of them.

We're talking travel trailer, right?

Why just the rear axle seals and not all four?


One way to determine what parts are required (seals, bearings, etc) is to crawl under and get the information off the axle as to manufacture, model, and weight rating.

Then check either the axle manufacturer's site for part numbers or a site like e-trailer that handles parts for most TT axles. E-trailer will list both the mfr's p/n and their own stock number.

Using the Mfr's P/N then call your local auto part's store (or go to their website if a chain like Auto Zone, Napa, O'Reilly) and cross reference to their part number.

Thank you!

Yes, Travel Trailer. I probably misspoke, he had mentioned rear axles but I think he is actually replacing all of them.

Heading out now to crawl underneath and check it out. Everything I was reading seemed to say I needed to take things apart to find the size, but I'm not too mechanically inclined so I was very wary of touching anything!

Come on back if you have any questions after identifying the axle and it's rating. Good chance someone else here has the same axle and may even know the proper part numbers.

A 2019 could have been around for a year already and it's getting an annual bearing inspect/re-pack.

I would advise anyone with a new trailer to go thru the hubs and lube relube the bearings and adjust the brakes to be sure it was all done correctly. I just do not trust the factory to have set things up correctly.
You need to replace the seals anytime you remove the hub to work on them.
