Today, I went for a trail drive, and about 25 miles in, I heard a clicking while driving somewhere in the front of the truck (I had to guess T case or front drive shaft).
After hearing, I switched it back to 2wd, and it went away, then back to 4wd, and the sound came back then to 4wd low, and the sound was a faster pace back to 4wd high and sound slowed down and finally to 2wd where it went away again.
Shortly after, my "Service 4wd" light came on.
I stopped, had lunch, then started the truck, and it was off again.
When the truck made this sound, the 4wd was working both high and low.
Also, I heard the noise for the first time last summer when switching my truck to 4wd to pull the boat up the ramp.
I figured maybe it wasn't engaged all the way, so once I got up the ramp, I switched it back to 2wd, and it didn't want to change.
I had to back up and forward and put in neutral to take it out of 4wd high.
I hadn't used the 4wd since then until today.
Any ideas or thoughts?
My front drive shaft CV Joint boot is torn, and grease leaked.
I thought the front drive shaft always spins 2wd and 4wd.
