2001 1500 4x4
I had my front diff rebuilt, the mechanic had the axle removed from the truck and after I got the truck back I started having these issues.
1. In 2HI, my 4x4 light comes on when the engine is under load: hard acceleration on a level surface or moderate acceleration up an incline.
2. In 4HI/4LO driving off road, the front end clunks and the 4x4 light flashes rapidly during a loss of traction.
3. When switching from 4HI/4LO to 2HI, it sometimes takes a few cycles of the shifter to get the 4x4 light to turn off.
I am thinking this is a vacuum issue because of the light coming on when the engine is under load. I have inspected the CAD area and found that the hose clamps on the CAD actuator were not installed correctly, I replaced them with brand new spring clamps and the acceleration under load trips the 4x4 light even more frequently. I made sure the vacuum connector was oriented correctly. Soon I am going to remove the CAD assembly from the axle and inspect it and vacuum test the actuator.
If anyone has some pointers I would gladly appreciate them.
