Failing the 4H Test?

[MHG]

Got me 2025 Taco home. Live on Long Island so off-roading places are limited. Beaches open on April 1. Testing putting it into 4L and 4H Saturday. Did. It seem to disengage from 4H (although the 4H icon went out). Drove and heard a loud clunk on a the . Backed up and went forward all seams good.

Wanted to test my 4WD so went to a parking lot. Put the front wheels against the curb. Stepped on gas and felt a tone of resistance. Engage 4H and it feels the same. Engage 4L and it goes right up the curb effortlessly.

Guess my question is, is it possible for 4L to work and 4H to display its working but not actually engage? I would think it’s the same inside the front did, just a lower gear on the trans.

Again, all indications on the dash tell me it’s engaging. I may have had the traction control on so maybe that’s effecting the 4H.

You’re overthinking it, my fellow Taco enthusiast. I’m sure it’s just fine, I believe it’s just a matter of gearing. Wait till those beaches open up and enjoy. Can’t wait to get mine on the sand sometime this summer.

4H engages whilst moving.

4HI engages easier while you’re moving. I usually do it around 25mph with foot off the throttle, coasting

Well I guess I can add some movement to the test. Although you would think the ADD is still engaging and disengaging the same differential .

You don't have to jump a curb to test the 4wd. Just drive around in a circle. Then on a straightaway, engage 4H and circle around again. There should be a lot of resistance when turning on pavement. You can do this at very slow speeds.

Transfer case has to be turning, for the 4x4 to engage.

That’s what I was doing g when I heard the gun shot pop. Trying to avoid doing that again.
