Wheel Bearings

[lwmcguir]

I agree with you Iwmcguir.
But there are people that will surely place the jack way in on the axle.
In this situation you are asking for trouble, so the manufacturer has to protect itself from people not doing proper lifting procedure.
I to have lifted my RV by the axles for the last 17 years and use blocking to backup my jack. But its under the springs.
The previous trailer had underhung springs, and the newer units have overhung springs that cause a problem of being directly on the axle tube.
The old method of backing up on a ramp surely is a no, no, to these heavy units.

Glad there is someone else on the same page as I am.

Does having wet bolts help the situation, or is that for another purpose?

Wet bolts are just to make the plastic bushings and the 9/16 bolts last longer. Keep them greased and you might get 20K or better before having to change them.

When Lippert changed my springs and installed the wet bolts they pulled out the plastic bushings and installed brass ones. They will last a lot longer being they are brass.
