Correct me if I'm wrong, please do, but there have been multiple conversations about the high speed gears, and multiple conversations about the longterm driveshaft problems with our trucks. If I am contemplating the high speed gear change (not delving into the reasons/logic, that has been beaten to death already), which is the best way to kill two birds with one stone?
1). have a custom CV driveshaft made for your LMTV, and it will reduce your likelihood of having a problem, but not too terribly much better off than stock configuration with a stock driveshaft in specs
2). clock the rear axle up 2-3 degrees, (both of these options would use just the high speed pumpkins)
3). replace the rear axle of your LMTV with the intermediate axle from an FMTV (fabricate new mounts, new driveshaft, lock the solenoid in the rear differential, and what to do with the spinning output yoke?)
4). 3rd member from FMTV intermediate axle into stock rear axle of your pre-2008 LMTV? I ask because BRYCE has high speed gears in the following options (complete front axle, complete intermediate axle, and intermediate axle 3rd members only).
5). combination of 1+2
It was mentioned that the intermediate axle 3rd member commonly fails if left engaged in the 6x6 configuration; is that just too much fighting between the axles, or do the complicated nature of the intermediate axle reduce the robustness?
