1990 Chevy Silverado V8 Four Wheel Drive Manual 115000 miles
1990 K3500 Dually, manual tranny. 4wd on floor.
4wd is not engaging while in 4HI. I can sometimes get it to engage while in 4LO. I was able to get in 4wd yesterday, but felt like it was not fully engaged.
Would this be an actuator problem or a weak one?
ordered a posi-lok for the truck to truly eliminate the actuator issue.
I also have read this could also be tied to an ABS issue, looking for feedback on this. I will try to pull the ABS fuse to see, need to wait for the blizzard here to pass.
have the same problem?
