How often do you teardown/grease your trailer hubs?

[Zac808]

My TT has greasable hubs but I recently read an article about grease getting onto the brakes if greased to often.

One pump, once a year?

When I had a travel trailer, every spring before first trip.

Zac808,
You jack the wheels off the ground and rotate them as you are pumping the grease in, you watch the front bearings and pump the grease till it starts coming out the front bearing. The trick is to rotate the hub as you put the grease in, Dexter recommends it this way and to do it once a year or 12,000miles which ever comes first. I would pull the hubs(drums) at least every other year to inspect the brakes.

I ma getting ready to do mine. As part of the "get ready", I was doing online research today and found this.

Every other year seems to be good enough for me. The thing is we all use our trailers differently we put on 3-4,000 miles per year some are going to do a lot less some a lot more.

I agree with 2500HD. Every other year. I also have the EZ lube hubs but don't use them for greasing. Too many seals blown out that way. Also some types of grease are not compatible. Unless you know exactly what type of grease they put in at the factory you could put in the wrong brand or type and create oil. Good read over on the Grand Design Owners forum about that exact issue.
I prefer to dismantle mine check all the brake parts and I know I'm getting it done right.

That is another concern of mine. I was going to use Techron Marine grease because I have a few tubes lying around the garage.

Every 3 years

Years don't matter...it's milage. Fully greased and sits for 3 years is still fully greased...you prolly have other issues if it sits for 3 years though.

Heat turns grease to oil, be careful not to overgrease and low out the grease seal...then you'll gets greased brakes.

Exactly, water and dust can also cause problems.

What kind of milage would trigger a bearing job? My TT is 3 yrs old but probably doesn't have 1500 miles on it.... I haven't done bearings yet.

I had a shop grease my bearings while I watched. After hand packing and new seals, the hubs run noticeably cooler. Trailer is a 2014 with about 5,000 miles on it. Brakes were fine. $172 parts and labor.

Hard to tell, best is with
conventional bearings to pull the dust cap off,
inspect the grease, if it looks and feels fresh you're good,
inspect the bearings,
tighten if necessary and fill with grease while turning the wheel

Never put the jack right under the axle shaft, put it under the spring assembly.
