Haven't done any trailer wheel bearings in a while and thought I'd best grease mine Saturday. I can't remember, do I need to remove the seals in order to get the bearings out? I'm thinking so but wanted to get confirmation. Presuming so, that means I need new seals.They're 6k Al-ko axles which I'm thinking would take a standard size seal, right? Anybody know the size?Thanks.

Front bearing, don't need to remove a seal.Rear bearing, yes, need to remove a seal.I would plan on all new seals cause normally when you remove it, you destroy it.

I did my bearings this spring. Definitely buy new bearings before you tackle the job. They're cheap and you don't have to worry about destroying the old ones taking the rear bearings out. They're all different sizes, so look up in your manual or on-line which size you need.

Yeah, no need to replace bearings, just seals.

After the first time you service the bearings, you keep an old seal or record the numbers for the future.

X2, If its the same 6k Alko I had on my other toy hauler I have the seal numer in the book in my truck. I'll look tonight for you.

You would need to know who makes you axle and model. Some axles have tags on them, sometimes it's listed on your specification sheet.
