Transfer case custom mount
- Thread starter 73K5BlazerSS
- Start date
If it makes you feel better, it was designed to be that way hanging off a turbo 350 which is smaller and less bolts.
A couple of things. Yes you are overthinking.
I have added a mount and had no issues with it breaking the trans on a 203. 203 is a big girl! It was peace of mind but totally not needed.
The biggest issue I have seen with nearly every aluminum transmission is pulling the threads out where the adapter bolts to the trans. If your gonna do anything helicoil ( or a like idea) those holes

I'll leave it alone (I'll remove the wood blocks of course). Thanks for all the help convincing me!
I just realized I may have really screwed up. I didn't think about the front driveline angle at highway speeds. I kept the 203 and converted it back to full time 4 wheel drive. I got the rear drive line set (rear is 6* up / xfer rear is 6* down / front pinion is 6* up / xfer front is 5* up). Will those angles in the front create vibration even with a double cardan joint at 65-75 mph?

Never driven a square in 4wd at highway speeds, but i would give a reputable driveline shop a call. Could be workable with the right shaft. What shims do you have up front? Removing those may help
just curious why you opted to go with a 203 vs other pass drop options with a 6L80? Was it for the full time 4wd?

I've gotta check I don't think there are any shims up front but I may be wrong.
The 203 came with the truck. I like the 205 but I couldn't find any at a reasonable price. After a ton of research on the 203 I felt that it was a pretty good case for my use. I'm not going to be doing any real off roading when it's done.

Is that a pressure treated 2x4?
Haha of course ! Should I rip some azek and box it in with cortex screws so I don't have to worry about painting it?
Would think there are probably some shins if the pinion is pointing up, i believe it is usually pointing down. What size lift springs are on it?
I know you said you had the rear squared away, but if you were to run a cv shaft in the rear, then you would have alot more flexibility on rear angle to accommodate better angle for front.
How did you accomplish the angles for the rear? Is the tcase dropped at all?
That's a good question. I can't see any part #s or names on the springs. I'm guessing its a 2" lift? With the engine, trans and xfer case (no body) it measures 12" from bottom of frame to top of axle. It didn't drop much when drivetrain went in.
I mounted the engine with dirty dingo brackets. I just angled it down to match the rear pinion.
How far can I shim the front axle without causing other problems? Right now it's pointing up 6*

I want to say you can point it down 5* but its been a long time since i messed with shimming front axle (longer shackles, and shackle angle can accomplish same thing). Shimming it up too much can create death wobble, but again I dont recall the degree at which it does that.
Try doing a little searching on here for front axle pinion angle, hopefully that helps a little bit

Beware of frame flex. Rigid mounting the case can lead to busted trans cases
Thanks for the info. Would you know what the stock front pinion angle was ? I'm guessing if my front pinion is 6* up, then I probably have positive caster which is not good.
That's a good point... obijuank5 mentioned that as well. At the very most I will get a mount just like my trans mount and rest the TC on it. Thanks guys !
Caster is measured at the ball joint axis and is 6* +/- 1* but 4* realistically drives well enough.
Is that 4* with the top tilting back?
Also am I understanding it correctly that any tilt forward is bad for front end wobble?
Yes the axle leaned back. The closer to 0 you get the more like that crazy shopping cart wheel you get.
I just measured it this morning. I have 0* to 1* negative measured from the top of the ball joint threaded post. I'm thinking this will give me an accurate measurement but I could be wrong.
So if I were to roll it back 4-5 degrees that would give me good caster and my pinion would be about 0. Is it acceptable to do this with a longer shackle and a shim?
Just curious... how would it get this far out of wack? Maybe my aftermarket springs were designed to be used with a shim?

Do this measurement when fully built.
Then you’ll realize why you want a part time kit.
