Run through 4h and 4l to keep transfer case loosened up?

I periodically run my jeep wrangler through 4h and 4l (yes appropriate conditions) to keep the transfer case loosened up. I would like some opinions on the need to do the same with the AWD 4Runner. Is it necessary? Thanks.

 

I believe it has electro-mechanical actuators to engage the center diff and 4lo, so I would cycle them regularly.

 

yes 100%. Been our Limited the city vehicle there was a time more than a month I did not use the center diff and when I did use H4L I felt it engaging little harder. Ever since I used to engage center diff lock on a straight road.
And L4L when possible, but sometimes cannot exercise L4L religiously every month.

 

Find a straight road for high and a parking lot for low.

 

Agree, 4L and center diff lock no longer work on my sequoia and 4H is very slow to engage I believe primarily because the wife never exercised them. It’s abuse it or lose it senerio.

 

Or a nice stretch of dirt road! I exercise my 4WD on wash day.

 

My Sequoia doesn’t go into 4L anymore because the wife never exercises it. 4H kinda works. I never drive it.

 

I do it almost everyday for a few blocks on a straightaway on my way home and typically on stretches where I know I will be going straight only. (referring to the 4x4 system but same idea)

 

Thanks to all. Will do.

 

I usually do it at the 1st of the month, easy for me to remember.

 

I usually need it once a month or more.

 

Yep, exercise those actuators for the transfer case and that little sleeve that connects the front axles.
