I’m still waiting for the DMV to process my title but I’ve been working on the truck and testing it around the yard. I tried the Ultra Low crawling gear. I heard a relay click in the dash and the 4WD light came on. Is this a normal feature? Also I have been coming to a full stop when I engage 4WD it engages and drives well. When I stop again and disengage there is a clunk I can feel through the entire vehicle. Is this also normal? I see it uses a vac solenoid back near the engine. I did replace the trans fluid with Redline MTL (gl4) and the diff with redline gear oil (gl5). I also replaced the right motor mount. The truck has 31k miles.
Yes, "Extra Low" puts you in 4WD automatically and engages your rear locker if you have one. Yes, you should feel the 4WD disengage.
