transfer case will go into lo and hi, but hubs are not locking.

what are some things i should be looking at?

01 2500 gas

 

Front axle central disconnect is all vacuum powered, with the engine running, see if you have vacuum at the front axle. (there are two lines, one should have vacuum in 2wd, the other should have vacuum in 4wd.) If you don't have vacuum there, work you way thru the system till you find out where it went.

 

are you talking about the 2 lines that run side by side into a saucer lookin thing on the CAD

 

That would be them.

should i be able to move/rotate the vacum shift motor? the little saucer thing?

 

yes, i think it will sort of rotate back and forth some. its just a vacuum diaphragm, attached to a shaft with the fork and collar attached.

the best way to get familiar with it and troubleshoot it, is to put the truck up on 4 jack stands and play with it. notice how right front (passenger) free wheels in 2wd, and locks up with the front drive shaft in 4wd. also since you have an open diff, when spinning tires by hand - one will turn backwards. you'll have to have the engine running in order to get a shift. but when you turn the engine off it'll remain in that 2wd or 4wd position.

 

i got vac out of the left hose on the motor, im guess its the whole motor, think im jus gonna get posi lock for it, id love to get a free spin kit and just eliminate the cad and unit bearings but i dont have 2k to through out there haha

 

Does the vacuum switch when you change from 2 to 4 wheel drive? (T-case lever.)

 

no same one
