With the snow we received over the weekend i used 4 hi most of the weekend. While starting my car for the day I decided to see what 4 lo is all about. It will not engage. It flashes 4 lo on the dashboard and also beeps at me. ANything I am doing wrong, or does something need to be fixed.

If you hear a beep most likely you are doing something wrong.

To go into 4LOW you have to be stopped and put the transmission in Neutral and than try to select into 4LOW. Try that.

I was stopped and in neutral

[chmura]

When was the last time you had it in 4LOW?

The actuator is notorious for freezing if not cycled regularly.

I cycle mine once a month.

You might have to replace the actuator with a new one. $700 part.

I have never had it in 4 lo my brother recently purchased a 4runner and they had to order a part because his would not engage. so I decided to check mine. any ideas on how to get it unfrozen?

[LUVDA4RUNNER]

How often do you need 4 lo?

[superg3]

I bought my 4runner used and had the same problem. I could hear something ever so quietly try to actuate and I was just persistent and toggled between 4hi and 4lo for around 20-30min until it engaged. Now I cycle it every few months and haven't had a problem since.

I rarely use 4Low, maybe twice since I bought my 4runner. So, I decided to test it since I read this thread. No issues, yes!

I occasionally need to move a few feet in either direction and then back into neutral before mine will engage. This was a little nugget in the owners manual.

well after messing with it for a few more days. nothing but the whine. gonna have the mechanic buddy give it a few lovetaps

Bought a 2006 Tacoma 4x4 TRD Offroad a few weeks ago. With 124,000 miles on it, I was concerned about the 4H and 4L, as well as the rear diff locker. Made the sales rep find me an off-road trail so I could test them. All worked fine.

Salesman got nervous when I crawled over some rocks.

[toyota08]

well no luck just the humming sound. im confused if it is humming why will it not engage?

[NuclearN8]

tested my 05 sport today (bought it a month ago or so...) no issues, slipped right into 4Lo, 4Hi and center diff engage and disengage with no issues. phew!

The 07 on the other hand still has issues (beeping) and refuses to go into 4Lo... when I don't have to lay on ice or snow to get under the truck I'm gonna give it some love taps while the wifey turns the knob, it's her truck after all... gotta make her work for it.
