As I suspected, 99% sure that the PTU actuator failed because of the internal motor that moves the forks to engage 4H and 4L... The dealer will aways replace the whole PTU set. If you weren't covered by warranty, other options would be available.
@Pombinhoecia my Cherokee is only a latitude, so there isn't a 4L option. How it was explained to me is that the Jeep is in front wheel drive, and when the front tires lose traction, the ptu transfers power to the rear, making it 4wd. I do have snow, mud, and sport selections for the 4wd, but again, no 4L. I come from the transfer case days where you had an actual stick that you moved to engage 4wd. 2H, 4H, neutral, then 4L. I think you're right, though, about the fork. I've never split a ptu in half to see how it works.
@Pombinhoecia that makes sense. I read that some jeeps with bad PTU's have actually rolled away while in park. Maybe that fork has something to do with it?
Hey mate, rod here from Australia. I have a 21 model grand cherokee.. got the same light on dash, aswel as the traction control & Fca lights on dash.. dealer can't get me in till next month.. car hasn't been running the same since. When it happened I was away on holidays so had no choice to keep driving it.. just wondering if you keep driving it will it damage other components, I'm not worried as the cars still well within warranty.
@deslauriersadventures we have a lot of snow, went to put it in 4wd and the light came on, flashing with the exclamation point. Traction control comes on (even if I have it off). Won't engage into 4wd, lose power, and acts like I don't have front wheel drive. Eventually the lights go away, but not right away. Very frustrating. RUclips videos say check wiring, the main switch to engage 4wd, wheel bearing, wheel bearing sensor.

@@deslauriersadventures yes, even single speed PTU has actuator and that fork to engage 4H when the terrain demands for it

@@deslauriersadventures nope, these are cases of splines wearing off and losing grip.

Hi my friend please
where is the put located ?
Is it in transmission or in the 4wd thanks
Was you 4wd light with exclamation point flashing or just on?
@lisaromeo7284 If my memory serves me correctly, the light originally flashed intermittently. Then, it eventually stayed on full time.

That was crap.
