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...

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...
