Less material, less strength. I would not do it. It would be nice if the spring eye was larger to accept a proper fitted grooved bushing. the 3 and 9 positions are best as well as a high pressure grease gun.

Has anyone ever considered taking a file or grinder to the wet bolts? Small lowered area (use round file to avoid notch) "groove" to allow the grease to get between the surfaces if clocked wrong? I know in some of our hydraulic jacks at work, they machine circular grooves and a cross way so oil can get under the piston if it's all the way down. Anytime you get fluid between the surfaces it helps to "lift" and possible get the fluid around to flow.

But, I built a brick slab to park on and set it to the correct height so the trailer was level from side to side. I was using my Level Mate Pro to adjust the hitch so that I was level from front to back. But interestingly, the Level Mate Pro shows that the heavy side is now 1-1/4" higher than it used to be. So I guess my spring sag under load was a little more pronounced than I though it was.

BTW I started through my MorRyde kit and so far I have found all the grease holes at the 3 OC position or close on the fabricated HD shackles. I still need to check more. I still need to get my axles ordered - been busy shoveling snow . I plan to mark the other wet bolts by the zerks for the proper orientation when installed..Did you ever get a picture of your blocking system?
Thanks - Keith

Yoda Hi Keith,
If the grease opening is pushed hard against the bushing, you will not likely be able to push the grease in. I know that it seems like this is where the grease would be needed the most . . . but, first we have to get it into the small clearance space between the bolt and the bushing. As the suspension moves, the grease will creep around the entire space . . . at least, that is the plan. The 3 or 9 o'clock positions are usually not on the heavily loaded path, so this is what most choose.
The point of the earlier discussion is that, even though MorRyde knows this, they provide components with the grease opening at random angles, requiring disassembly of bolts and shackles and proper alignment before installation.

This may sound like a dumb question. In what orientation do you put the grease outlet hole during installation, or does it matter? I understand that a 6 OC it could be under suspension pressure and hard to grease, but that is that not where the grease needs to go. Is the 5-7 orientation better or 4-8? I have read folks say 3-9 position to have the least pressure. Maybe I am over engineering this - like usual

Now I get to have fun checking all the welt bolts I have in the MorRyde kit and those from the X-Factors. Good to know this going in. Jim - can you explain how you determined which hole needed to be deepened? Did you just insert a stiff wire and compare depths? Hope I don't need it but I do now have a drill press - some assembly required.
Thanks

I've only installed one wet bolt so far, I'll check all the other ones to make sure they work fine. After all, they're from MorRyde, what can go wrong? All of the wet bolts easily passed grease through them! BUT - I had a teeny tiny nagging feeling about the one I'd already installed. But, if statistics mean anything, if you have 13 wet bolts that take grease, what are the odds that one won't? I'll tell you what the odds are - they are 100% that son of a gun is defective. I had the entire suspension assembled and all the bolts took grease.... EXCEPT ONE!!! Yep, that rascal would not take grease at all.
So I removed the wet bolt that was holding the CRE3000 to the hanger, and tried pumping grease while it was out of the RV. No dice. It was plugged solid!! I took it to the garage and switched the zerk. Still plugged. Come to find out, the small hole on the side of the bolt was not drilled all the way through. I put the proper size drill bit in the drill press and had to drill a few thousandths before it opened up. I put the zerk back in, and boy, did that baby take grease!!! Yipee. Ten minutes later it was reinstalled and torqued with a new nut and took grease just fine.
There are two lessons.
1. Try pumping grease through new wet bolts BEFORE installing them.
2. Listen to Rob.

Hi Jim,
Thanks for the compliment . . . Murphy is always watching over whatever we do. You can guess how I learned that not all wet bolts are correctly drilled .

Don't laugh at the name too hard, but these were handy when in WI for a winter. Useful for round object rolling resistance (put in middle let bag deform) or counterweight in the bed of the truck. https://www.homedepot.com/p/Quikrete...5960/100318522

I have had the OTC combo for several years and use it for many more things that we can discuss without the OSHA GODS from dying and rolling over in their graves fast enough to power a small country. I can honestly say it has gotten me both into and out of trouble more times than I care to discuss. It's done everything from help change tires, to being a torzue multiplier for breaking caliper brackets loose where I could not get an impact on the bolt.
We will not discuss using a jackstand upside down against the spare to lift the rear of the truck to "unsprung" the rear leaf springs.....
