question for all the suspension experts...

[comegetsome]

ok i picked up a 85 crew cab dually im bout to start bodydropping as soon as we get room in the shop...my only real question is how do i set up the carrier bearing...im gonna do a 3.5 inch z...ive got my 22 semis for it already so a 3.5 will be plenty to lay frame with stock arms...but after i move it up do i move the carrier up the same cause if so that gonna be a hell of a trans tunnel haha...but in this pic he z'ed the frame and stock floored it but didnt appear to raise the bearing...my bearing is on top of the crossmember and his is flipped but doesnt appear to be any higher...so anybody got any ideas

[comegetsome]

well aint that a bitch...nobody knows a answer

[numatk_07]

Sorry dude. You may be on your own with this one. Does the tranny have to point directly at the carrier bearing? Or is that what you're asking? I bet there's a way to leave it lower.

[comegetsome]

thats what im asking...can i leave the bearing where it is and raise the motor and trans or do i need to raise it the same...id rather leave it where it is but if it gonna viberate and have problems...

[04gmcridinlow]

i dont think it has to be strait with tranny

[sickgmc]

you should be fine. when we installed the 2 peice in my crew cab its higher at the trans than my carrier and i have no problems.

[comegetsome]

ok thanks man...i think im gonna try it where it is...as long as it dont viberate ill drive the shit out of it

[cajundragger]

I think you'll be fine.

if you have a question the guys at inland empire driveline or even a company like moser os something can help you out to make 100% sure.

Anytime i raise my transmission, i always raise the carrier bearing. I also raise the carrier beraing to work with my rear suspension so that I get a more usable working angle, while riding low. And honestly, the way the floor is built on these, the tunnel isn't bad. We've got the cab back on this one and its not bad at all. I will snap some more pics tonight

[narleycarley]

I think you SHOULD raise it to match to get back to factory

But I think you COULD get away with it. But if it's a daily driver it won't work very long

[squeak]

seems like it should be raised to be level with the transmission, otherwise the carrier bearing is going to be the lowest point. unless our ride height is really high, both driveshafts are going to angle down to the carrier bearing. you might can make it work but it wouldnt really be right

needs to be 3 degrees different than the shaft in front of it. Id say mount is as low as you can to lessen the floor hump or at least dont mount it any higher than the rest of the floor hump. Theres lots of room to move it up and down as far as driveline angles goes.

[comegetsome]

got it tore apart lastnight and worked on it all day today...heres a little teaser pic...will be pullin the cab and drivetrain monday and tuesday...ill start a build thread as soon as we get further along with it....and also...dont ever buy a truck that come from the beach....rust sucks ass

[squeak]

3-5 degrees yes, low as possible no. You ned to plan your driveline angles out. If you are running a massive wheel and tire, then the center of your pinion yolk will be much higher, so it will very difficult to find a good working drive height. I understand what he means by leaving it low to adjust it, but if you plan everything out, adjustment will not be needed.
