wonder if it would be a good idea on truck with some miles, some of them towing miles, to go through the effort to drop valve body, find the bolts and remove them, add some maybe blue locktit and reinstalled at proper torque.. ?? sounds like an expensive problem that can be corrected quite cheaply. not having to be towed somewhere is alway better in my book. who how hard is this to do?? any video of the procedure??

Per the manual: "After removal, discard the feedbolts. The bolts will not retain torque specification if reused. "

The reason they say not to reuse them is they are coated with a dry threadlocking sealant. If the threads of the Feed bolts, Center Support, and OD-Intermediate Cylinder are cleaned & dried, a threadlocker can be applied and bolts retorqued. One of the reasons the bolts loosen is wear on the Center Support pads; causing movement as the clutches apply. Retorquing them can buy some more transmission time, but does not address the root cause.
Do JW or BTS Transmissions solve this problem with a new center support?

DUAL LOAD CENTER SUPPORT MACHINED FOR MORE STRENGTH
Here are some pics of the wear on the Center Support Housing and what causes the "walk" within the Trans Case and loosening of the Feed bolts. Also shown are the solutions to this: Machining of this Housing and the addition of a Spacer Ring to eliminate slack and increase surface area contact. Some go a step farther by machining the Center Shaft smooth and the inside of Support Hub to add a bushing w/ oil grooves. I am not a fan of the bushing add-on as you can see what can happen in the last pic. I went with the machined aluminum Housing/stock steel Support Hub, new bearing, and a cryo'd Center Shaft after it failed. I haven't had any issues with just using the machined Housing/Spacer Ring combo.
