wet bolt on suspension

The wet bolts I got from eTrailer had zerks pressed in, they were not threaded.
A third of them also wern't drilled all the way. Just far enough to press the zerks in.

Maybe that should be something that should be checked before installation.

I typically remove the zerk and use a properly sized drill bit to remove the old grease. I realize this doesn't remove the grease in the "cross" hole but I have never had one to not take grease after the drill bit trick.

I know of no kits with grooved bushings, you have to roll your own.

If you use a small bottle jack and place it right at the end of the spring within the hanger, and then jack till it takes grease. You may have to jack till that tire comes off the ground.

What is happening is that the bolt and bushing wears to a perfect mating and the small grease hole would take thousands of pounds per square inch to flow some grease. To head off that problem and get grease to flow to where it is needed, carve a figure eight inside the bushings before installing, you can't make it very deep because the bushings are thin. Here are some examples of what I am talking about.

Having never seen a wet bolt kit, I didn't realize that the bushings =weren't= grooved. I know all the bronze bushings I dealt with on our farm over 40 years were grooved. Does anyone make a kit with pre-grooved bushings?

When I installed mine I tested each one for taking grease before installing them. Even then with them installed in the horizontal or correct position some still wouldn't take grease. As others hear mentioned take the wieght off and it should work.

The weight should be you would think on the top or bottom, same here tested before, and will still not take grease regardless of what I do. Don't have much solution for that other then removing ,and greasing them ,and reinstalling , not a fun job.

When greasing wet bolts the weight should be removed.

If only that worked all the time, no guarantees . The just flat too tight in there ,no matter the position they won't take grease. I know ,been there, yet they will out of the springs .

Cummins2014, that's great to hear everything was in such good shape. What kind of fiver and mileage?

2008 Montana 3400RL , have had it since new . It was like three years old, when I changed out the nylon bushings to the MorRyde wet bolt kit . . At the time hearing the horror stories about these nylon bushings, and as I was doing it I kept seeing these nylon bushing coming out looking like new, and thought why am I bothering doing this ,but I had the kit, so I went ahead with it.

I only had a few thousand miles on it at that point. Now I never kept track with my previous truck this new one keeps track of the towing miles, averaging the years and mileage, and going off of that I am right around 50K on the fifth wheel after nearly 12 years , average just a little over 4K per year, not a lot.

This coming year ,its Alaska for the summer , thats probably going to be around 10K when finished. Bearings are packed this spring, and it only been 600 miles since, and no plans this winter for Arizona staying home . Had enough traveling this year . So tires are three years old, bearings packed , new shear springs on the suspension, good to go. Actually the fifth wheel for its age is in pretty good shape. Had to replace a few graphics, and hydraulic hoses.
