Hey guys , I’ve searched through the threads for this one
I drove back from eastern Washington basically all day in 4wd because it was all ice,
I got over the mountains then was able to switch to 2wd, drove another 100 miles or so at around 80mph noticed the service 4wd light come on with a high pitch grinding sound coming from the front , the noise went away and the light went away, we made it all the way to our exit and when I let off the throttle the light turned on and the grinding noise came back, as I was slowing down the grinding noise went in time with the speed all the way to a dead stop the we heard a big thump, the noise suddenly went away. I checked under the truck and didn’t see anything out of the ordinary.
Start driving again , all good, then the light turned on at around 35mph and the grinding sound.
It kind of sounded like the transfer case ? I don’t know ,
I had my kid turn the 4wd switch while I was under the truck, the transfer case actuator and the 4wd actuator made noise like they are working.
I pulled the 4wd actuator on the diff, pulled that apart, played with the gears that run the fork, no binding or broken teeth, there was some moisture in there , cleaned it up and sealed it. The color in the diff slid back and forth very easily. I’m about to pull the transfer case motor
Any hints on what could be wrong would be appreciated.
