It's finally time to go camping this year, so I just serviced my hubs for the first time. Thank you Herk, for starting this thread. I was glad to be forewarned on the amount of grease it would take to fill the hubs.

My Mini-Lite is only a year old, but 2 of the rubber axle plugs were cracked through. I ran over to the local RV store & bought 4 new ones. Anyways, hope to hit the road next week.

The big chunk of rubber came out of 1 of my plugs this spring , as well as cracks in the other 3. Replaced them all at a couple of dollars each from a local horse and cargo trailer dealer.

As a recent member and being very interested in this subject, I've read all the contributions and comments in this thread, which has been very informative. One thing I'd like to point out is the AL-KO spindle lube design is NOT called Ultralube. The correct name is Ultrulube with a "u" after the r.

The problem comes in that all they are doing after assembly is screwing the Zerk fitting into the end of the axle (in some cases only a thread or two and hand tight) and NOT pumping the axle hub full like they are supposed to.

When you lube from the Zerk for the first time, you need to fill the reservoir between the inner and outer bearings, the space between the trailer side bearing and rear lip seal, push the old grease out of the trailer side bearing, push THAT grease along the outer spindle, and through the tire side bearing and then clean all that mess up.

Since mine had never been done before, it took an entire "large" tube of grease and almost a roll of paper towels.

IMPORTANT TO NOTE: With the easy lube type system, you do NOT need to remove the bearings to repack them. You just put the hand pump on once a month and give a few squirts. When you do your brakes, you should pull the bearings and inspect them for burn marks, wear, and damage. You will need to replace your seals when the bearings come out so make sure you order those too.
I truly appreciated this timely information. I am going to repack my bearings this weekend for the first time; I also have AL-KO Ultrulube that came with my Rookwood HW277. I noticed the pdf, attachments. I will use them as a reference for procedure, truly appreciated, thank you for that.

Do you have any suggestions as to doing my own break inspections as well?

I sure hope this is not a thread hijacking; the thread is about two years old, sorry if it is.

Without knowing your level of skill, I hesitate to say.
Since in PA the camper must be inspected annually, I let them do it.

As far as I know, there is no such law in Montréal for a tent trailer, I will investigate and let you know. As for my skills, I am not an auto or RV mechanic, so if it goes against your principles, I respect that.

I contacted Transport Québec, and they said an inspection is only required on RVs or any trailers over 4500 Kilograms or 9921 pounds. My Rookwood HW277 is GVWR 3859 pounds.

Dealer Repack! NOT

Been reading this and lot of interesting info here. Thanks to all who have posted. Have my 831 RLBSS, 2011, for some repairs( swung around to tight the back end of tt caught a solid object) so asked dealer to look at dark stains running down the outside, not the backside of the wheel on 2 of the 4 wheels. Its leakage from bearing grease, I believe. Anyway got the estimate at @$220.00, so I emailed them back asking for clarification as to what exactly would be done for $220.00. Dealer replied today saying "Repack bearings, replace seal, clean brakes." Unclear IF they intend to replace all the seals? Will ask for clarification. They also stated seals were not a warranty repair item even tho we bought extended warranty.(Thats another story for another forum I have the AL_KO Ultralube type bearings/hubs.
Anyway thought that to be rather high cost! TT has approx 15K miles.
