EZ Lube

I have a question about the EZ Lube. I have a 2011 travel trailer and I want to put grease in before I head to Florida. It says to rotate the hub as you pump the grease in the EZ Lube. I unfortunately cannot jack up the travel trailer to do so. Can I put grease in without rotating the hub? I have Coach Net and Good Sams in the event that I need to have a tire changed so that is why I don't have a jack. I was just wondering if anyone ever did so like I just mentioned above. Thanks.

I don't think you're going to hurt anything but you won't be evenly distributing the grease. You could try pumping it until grease comes out, drive it a ways and pump it full again. Or just get you a bottle jack. (6 tons works, 12 tons is better) My philosophy is better have it and not need it than to need it and not have it. But you need it.

This topic has been extensively cover on iRV2 and on many other RV internet forums. I suggest you look there.

My recommendation is to do a complete repack of all your wheel bearings and do not touch that zerk fitting.

Bob, he doesn't have a jack.. He's not going to be re-packing. At least not without a jack. And I don't know that I'd recommend that *everyone* repack unless they know what they're doing. It'd be easy to get something too tight or too lose.

Greasing the zerks before leaving (with the trailer sitting) is better than not adding any grease, but I agree with above.. When you hook it up, grease it, drive it 2', grease it again, repeat.

I wouldn't own a trailer without a jack. Even with coachnet and GoodSams, you're still subject to the availability of someone in that local area... And if you're out somewhere that isn't urban, it can take hours... Lots of hours...

You need the jack to be able to inspect the bearings. Before *any* of my trailers go on a trip, I'm under the axle and checking the bearings for play. You do this by "wiggling" the tires. It's easy. If you feel play (in and out) - you've got a problem. If you've never done this, I can almost guarantee that you need adjustments.

Use a Quick Change Trailer Jack. Lite and easy to store.

Thanks everyone. I purchased a jack. My understanding is that you have to place the jack under the axle and not the frame of the travel trailer as it will damage the frame. I did talk to a friend of mine who is a mechanic. He said I could put grease in the EZ Lube and drive forward a bit each time as he does that with his 5th wheel. I am going to give it a shot. I am a bit nervous on using a jack as I have never used one before. Am I correct on placing it directly under the axle? Thanks.

I have seen it in other threads where you can blow the seals by not rotating the tires. I have the same system but I do the repacking manually...do a quick search for more info before committing to the roll your tt method, which I don't think is anywhere near good enough.

Nj1963,

Get some help. Jacking it up is easy - but if you axles are round, jacking on them can be a concern. Find a neighbor that has done this sort of thing before.. Likely it'll be a 20 minute tutorial.

Contact the TT's manufacture for instructions on where to place the jack. On mine the jack is placed on the frame a near the springs as possible.

Before going on the trip he has planned, I agree he should have a jack. In his situation I would hookup and tow it to the nearest good brake shop. And repack. Here is the consequence of using the zerk should the grease follow one path of least resistance, i.e a seal that offers less resistance than the needed path going through all the bearing interstices.

Make sure the grease you use is EZ-Lube compatible.

You can get grease that doesn't work with zerks?

You do know that there are different types of grease and they are not to be mixed? Do you know what type is in there now? Do you know what your mechanic uses?
