Its more about just being conferrable and being able to take one's time. Nobody want's to work in the cold on an unfamiliar project. The cold weather just freezes zerks sometimes due to moisture in the air during time when not in use...storage.

When to grease axles

We own a 2013 Rockwood Mini Lite camper. Is it recommended to grease the axle at the beginning of every season?

I'd suggest you have the bearings examined and repacked at the start of each season unless you don't put many miles on it. Then you can use the grease zerk and give it a few pumps once in a while throughout the season.

Please forgive me if the answer has already been posted, but i couldn't find it. Has anyone used Bearing Buddies on the Ultra-lube axles. Would be interested in hearing your opinions regarding their use. Thanks

Bearing Buddies are good for axles with no brakes, but not for an axle that does have brakes because if you happen to have a leaking seal, it will constantly force grease around the seal and onto the brake shoes.

Lubricating the wheel bearings HELP! Oh boy, where do I start? I guess by telling everyone I am as far from being a mechanic as a sofa salesman can get. My Rockwood 8329ss was delivered in January 2014. Since then we have put about 7000 miles on it.
What are the chances I need to lubricate the wheel bearings?
I'm driving from Phoenix to Chicago starting Tomorrow and am scared I will break down.
How often in miles should the bearings be lubed? Any comment will be greatly appreciated.

Wheel bearings need to be cleaned and inspected, then repacked every year according to the manual from Dexter, Lippert, and Al-Ko.

If you have "Ultra-Lube axles, you can lube your bearings before every trip by pumping (ALWAYS a hand pump; never air) grease into the Zerk fitting until fresh grease appears, Rotating the wheel as you pump ensures evenly distributed grease.

You would be wise to grease the bearings before you leave. Make sure you follow Herk's advise. Use Lucas Red "N" Tacky grease. You will need at least 2 tubes, better get 3 just in case. TAKE IT SLOW & EASY.

Hate to nitpick but for the record and as regards RV axle hubs that allow for in situ greasing of the bearings...

AL-KO calls it: Ultrulube
Dexter calls it: E-Z Lube
LCI (Lippert) calls it: SuperLube

"Ultra Lube" is a line of lubrication products.

Interestingly, LCI appears to be the only axle supplier that recommends rotating the wheel/hub to distribute the grease. I recommend that for any of these systems and be very careful when the axle components are cold - even with a double lip seal. I learned this the hard way. And if I may, when the integrity of the bearing assemblies on your new or new to me RV have been ascertained (inspected/replaced, repacked, new seal), and you tow infrequently, it is overkill to be pulling the bearings out annually. If you're feeding the bearings with a steady supply of good lube via one of the aforementioned systems, your bearing inspection interval (my opinion and experience) can be stretched to two, three or four years. I appreciate that many RVs sit inactive for inordinate periods of time. However, if the bearings are adequately packed with good grease, sitting idle for a year and then some will not normally be an issue as regards the performance of said bearings.

I would concur. There is another poster here that has never pulled his hubs on a 2012, well known one actually. I am at year 2 in July. I may pull my hubs then, can't at home my driveway is slopping too much.

Hey Guys.....just curious, regarding seal failure from over/greasing.....is the entire seal/assy. being forced out of position due to hydraulic pressure?....or is the grease only bypassing the seal/lip? ......Thanks for any input.....

Grease is blowing out thru the rubber seal.
The body of the seal is held in place by friction and the spindle nut.

Mine is a 2013 @ 3 years never pulled the hubs. I think a lot of the issues come up went the hubs / bearings are pulled too often by those not experienced in the proper methods. We won't even talk about the last time I did any of the utility / cargo trailers............

I have a 2011 5er, I haven't pulled the hubs, but inject a few squirts of bearing grease in every season. I only pull about 800 miles a year, brakes are good, and my tpms says heat is normal. I might pull them next spring, but I don't want to screw up something that presently works ok.

I pulled mine for the first time this year on my 2012 popup. It wasn't to pack the bearing it was to replace the brakes with a larger size. Bearing were in excellent condition; no leakage past the seals.

I was always told that if you pull the hub/drum off, you need to replace the rear seal with a new one; even if it is just to check the brakes.

Explain to me how the spindle nut has anything to do with the seal that is approx. 2.5"-3" away from it, other than holding the hub in place. The seal is held in place due to an interference fit between the hub and the seal outer diameter. The lips of the seal are designed to exert a slight extra pressure on the spindle when grease is added. The lip of the seal is angled in where it contacts the spindle.

Question. Even if the seal is held in place with an interference fit, doesn't it back up and contact the brakes assembly's backing plate? So it cannot move in that direction? I'm asking, just curious.

Guess I could go check the two I have in my going to the dump pile of metal parts.
