That's for sure! Mine took a LOT of grease the first time. And that is an important first thing to do when you get your new trailer.

Grease
Use a high temperature, automotive type wheel bearing grease produced by a reputable manufacturer. The soap type should be lithium complex or equivalent. Use NLGI Grade 2 product
with a minimum dropping point of 440o F.
I assume the link you posted meets these specifications.
I will look for it or a comparable product at my local NAPA outlet.
Thanks again for all the help.
Jim
The drop point in Red n Tacky is a bit thicker than the minimum and still flows very well using my hand grease gun. I like the red color as it makes determining when the old grease is out. Any NLGI #2 lithium complex exceeding 440 is good to go.

Yes, on the Red N Tacky with a Drop point of 540. I went 3 years before repacking. just because I didn't know any better. Sort of Out of Sight out of mind. When you first buy your camper that sort of thing isn't discussed nor brought up. You either find out the hard way which is when something happens or by accident when it happens to someone else and you hear about it and the wheels start turning. I would do what the manufacturer recommends. It is always good peace of mind to do it and know that it is done before you start traveling. preventative maintenance.

This is an important point. The technique in my post assumes you start from known good freshly packed bearings. If you have never had them done, don't start just using the Zerks.

Get them inspected and repacked by a competent mechanic; then you can maintain them yourself using a similar technique. Obviously you can have them repacked and inspected as often as you feel comfortable with.

The MFR states annual inspections and you can certainly go with that if you are comfortable repacking them yourself. Having a shop do it annually is an expensive option, though.

Thanks to all of you for the good info,we are heading out on our first trip of the year this Friday. So i thought i needed to address the bearings. I have a 2011 Roo 23ss so i have 4 bearings. I had bought grease a couple of weeks ago it was Lucas brand Marine grease NLGI Grade 2 Lithium with a drop point of 550,so it exceeds the specs. It took 10 pumps each to get the grease to start coming out then i put another 30 in each, thought i might be running out so stated over puting 5 in each then 5 again and new grease finally started to come out of the first one and i ran out, so i think i am good to go! I do have the Ultra Lube Axles that Herk 7769 talked about. So again THANKS everyone, Now time to start CAMPING FINALLY!!!

I've had mine repacked once already and will be due after this summer. My RV dealership said after so many miles, but I can't remember how many he said. We didn't camp much in '12 and did mostly local last summer, but just took the Roo to TX, so once I winterized in the fall, I'll pay to have them repacked.

Repacking wheel bearings is a dealership moneymaker.

Too each his on but from reading other forums I believe that the EZ Lube has mixed success. Seems some grease with the wheel off the ground and go on down the road while others blow seals and ruined brakes. As a minimum I would inspect each brake to ensure that grease has not gone past the seal and onto the brakes. That will give you an idea the condition of the system.

Wife's cousin followed the jack it up, spin the tire while injecting grease. After nearly crashing he found the brakes coated with grease and $600. later he decided that inspections was the route to take. As for me, I inspected the brakes when I got my rig home, repacked and do another inspection every 2 years. The manufacturer of the EZ Lube system says you still need to do an inspection of bearings. Sometimes by age and sometimes by mileage.

No matter your flavor of maintaining, I've never seen a well maintained cage bearing fail. All that I've seen failed were neglected or improperly adjusted. YMMV, all disclaimers apply.

Seen quite a few in our Test Dept. @ IH East Moline & Hinsdale. IL years ago and some were in oil bath systems i.e final drives/transmissions. Bearings do fail from defects as well as from improper maintenance/adjustment.
