Lmao! I have been thinking about doing axles though.

 

^^^ At least get them under it. You can build them later on as funds allow.

 

The funds have to allow for me to get them first

 

I really don't know 'bout this throttle body spacer thingy... Aren't those for carb'd engines?

 

^
*facepalm*

PLEASE tell me you're joking about not knowing....

 

It's just a joke Dlyter and I like to pass around from time to time.

 

Good... Cause I don't see any way they would do anything on these fuel injected engines.. LOl

 

Sorry for getting back to you late and thanks for indulging the questions.

Consider that the whole drivetrain is rigidly connected, all bolted up, there is no flex. Only bouncing or flex goes through that tranny/tcase mount. I asked about its condition b/c I've seen a picture of a broken one....2x. It will then allow movement and bending loads to occur b/t the tranny/tcase in a bad way. Even the degradation of the bushing/rubber material can/will behave negatively for this. I'm sure you'll replace new given the new tranny/tcase coming in anyways.

Furthermore, my other questions are all related to the stiffness of the drivetrain/alignment and expected movement. For example, if the ubolts loosened up or something in the perches etc. allowed movement, then you might get the axle to spin a bit. Honestly, this would probably be something noticed very easily as the perch(s) would probably fail... Putting that aside though, consider if your axle pinion angle was out of spec. By itself also probably something that wouldn't contribute to your failures. Yet couple it with a possible binding slip yoke on the tcase. If the slip yoke is not slipping, then what will it do? It will bind. The bind will then be able to put a load into the entire case (bending).

Hard to show the latter b/c you've been through 4 tcases and I can only infer the same thing happened. I probably missed it. Other thing is consider the breaks to all be progressive. Meaning something else was stressed before that didn't yet lead to the current break that included part of the tranny.

Buddy of mine wheeling on original axle ujoints. Goes hard driver and in reverse. Driver side HUB breaks. Cool, easy fix for the most part. 2 weeks later same fricken move, breaks the passenger side ujoint, additionally splays open the stub shaft yoke. The first break 2 weeks before also contributed to the 2nd break.

Some things to consider during the time you put this thing together. Hope it was helpful.

 

this might be a sorta stupid thing to say, and I am slightly uninformed here, but have you guys checked your mounts?

And not just the engine and tranny/t-case mounts..

What about the rear axle.. how old are your springs.. how far is your axle twisting now-a-days on load up??

on a side note, I always stop before shifting into 4 low.. as for 4 hi, it says on the fly.. i've shifted in and out at 140km/hr with no issues, no banging clanging etc, several times.
