Well so far i think i got it fixed, ive driven about 150 miles but it has sliped twice but i think thats just the connection. I now have another problem, my 4wd wont engage it gos into 4 hi and 4 low but only has 2wd. What could it be?

 

Check the cad..

 

Whats the cad?

 

Central axle disconnect. It's on the passenger side of the front axle. Vacuum controlled from a switch on the t-case.

 

Shold i check the switch itself or the vacuum lines? And does anyone have a routing diagram for the vacuum lines?

 

Mine had a leak in the rubber vacuum manifold that presses onto the switch on the T-Case. While running, in 2wd, pull the hoses (ONE AT A TIME) at the CAD. Feel for vacuum on one hoses. Put it into 4x4 now. Check again, there should be vacuum to the other hose now. of not, you either have a vacuum leak at one of the hoses, switch or the switch itself is bad. If you don't get vacuum at all, there's a vacuum leak leading up to the switch from the back of the engine.

 

Well i havent got a chance to look at the vac lines but my trany and a new problem once i shift into o/d it shutters really bad, but only in o/d if i shut o/d off it works fine.

And suggestion's?

 

Engine miss. When's the last time you looked at plugs/wires/cap/rotor? Fixed the plenum??

 

I havent with this truck, but i did just get the heater core flushed todY maybe the guy wiggled something loose

 

If it was an engine miss wouldent it do it in other gears also?
