I will be there early Saturday and hope we get more guys from SS to stop by. I sure hope the weather will be a little better and hope the trail is not a mud slide. That mud is like concrete and a real bitch to get off the trucks. Mark

Always good to keep it simple. Great for tailgate parties.

I concur. Start with the basics. I suspect you have a real problem with at least one battery. Those caps don't just "pop" off. Mark

An very old engine cleaner was to add a qt of kerosene to the oil with the engine cold then bring it up to temp and let it sit and repeat. Change the oil and filter. The kerosene will cut though and dislodge the sludge buildup and hopefully clear up any issues. It does help. Mark

Make one of those quarts of oil a quart of Marvel mystery oil as it can help get things unstuck. Mark

Pick up an inexpensive Stethoscope to help localize the knocking. A bad injector could be the culprit. I had picked up two nos injectors for 40 bucks shipped from flyaway just in case I may need them in the future. mark

Good point!

Check the tranny mount. Mark

Never said this is a permanent fix for a broken boot. If a reg boot is good for 80k which seem to be the standard then even if I get half of that or even a quarter of that it would last me years. If it fails I will replace the shaft. Not trying to reinvent the wheel here as I was just looking...

You can pull the head but as many of us here think it won't be pretty. I would pull the head for the hell if it but start searching for a replacement engine. It happens. Mark

With the engine ONLY at 3k rpms the CV shaft speed is around 1200 rpms. That is the only number I have been looking for. If you change the difs gear ratios the CV shaft speed will also change given the constant 3k engine rpm. The portal and the tire are after the fact as I was just looking at CV...

If you add in the portal gearing you end up with a final ratio of 1.92:1 you end up with a final ratio of just less than 4.46:1. With 37" tires the math all works out.

Thank you. I fail to see that our half shafts are running any faster than a reg trucks half shafts. Mark

Forgetting the tire and the portal for a moment at 3k engine rpm and with the transmission in 3rd 1:1 and now we add in a 2.56 dif would not the CV shaft speed be 1172 rpms? I only simplified this as 3k would be the max rpm and given this the maximum rotational speed of a standard M998 with...

The pumpkins are a reg ratio in the HMMWV the portals rev up the system to handle the tall tires. With these diesels maxing out most of the time around 3k the boots should see a lot less rpms than boots in a car reving to 6k. Mark

Had my outer pass front CV boot fail. It had just happened so all the grease was still on there and no water. After doing some measuring and then research I found the proper speedi boot for our 10k outer CV shafts. Quick install and repacked with grease provided. I like these speedi boots...

The ground connection spade should be a direct connection to the shell of the assembly and when using the ground line to the mounting bolt the assembly is now grounded to the truck. Knowing the connectors put 24v to the power connector and the ground wire to the new battery. The unit should...

Which wire are you calling #27? On the schematic the top wire is ground. The second wire down is power. The third wire down is to send power to the washer pump. The ground ring wire goes to one of the mounting lugs for the assembly. If you are bench testing the unit, use a meter to determine...

Yes Dex III is the one I would go with. Mark
