2000 Dodge Ram 1500, Laramie V8 - 5.2L
While trying to figure out why the 4WD light flickers on and off (when in 2H, it is off while stopped, will come on or flicker after 15-20mph, may randomly go off at 60mph) I was looking under at the front axle and I noticed there is a red/black tube pair.
When I followed it up (just a foot) I noticed the red tube was broken. When I pulled the protective sleeve down to see the red tube , the red inside the protective sleeve snapped off.
So my question is, what is the importance of this red tube, and could it be related to my 4WD indicator light issue?
After closer inspection both the black and red tubes had broken apart. I managed to patch them using some thermal tubing, but I suspect that won't actually hold any pressure.
