Throttle bogged down in 4H

I got my Tacoma (2017 TRD OR) about a week ago. First 4x4 vehicle I've owned. After lightly reading the owners manual it states to drive on 4H for at least 10 miles per month to lubricate front drive components. Driving round my neighborhood I decided to use the 4H setting to give it a try at slow speed (10mph max) to see how it works and to get familiarized with it.

Something I noticed is that while making a sharp turn the throttle bogged down. Is this something normal while on 4h setting?

Any 4x4 do's and dont's I should now about that aren't mentioned in the manual?

Thanks in advance.

 

First rule: Don't drive on dry pavement in 4x4

 

don't use 4 wheel on dry pavement, you can shift into 4h on the fly up to I believe 62mph, but I wouldn't go that fast, if you do use 4w on dry pavement stay straight and don't turn. Find you a dirt road and just use it on that for a few minutes. You'll be fine.

edit: if you do use 4w on pavement and turn, you'll bind the components and run the risk of something breaking.

 

...oh no. you are not supposed to turn in high traction situations when in 4wd. the front tires will bind up because they are attempting to rotate at the same rate but the inside tire is going to rotate slower than the outside tire. its not a big deal that you did it but don't do it in the future. its fine to do it in low traction situations like on dirt or in mud or whatever. be ready people will probably give you hell here.

 

You were just getting bound up in a turn, which is what will happen in 4x4 unless you are on gravel or snow ... etc. Try to keep in a straight line if you are on dry pavement. Turning in a high traction environment probably won't break anything for a while, but it's certainly going to wear parts out quite rapidly.

 

Don't ever use 4wd on any surface where the front wheels can't slip if they need to, you'll bind up the drivetrain (which sounds like what you experienced) and can cause damage to the components that way. If you have to for whatever reason then make sure you're going in a straight line.

Damn in the 20 seconds it took me to type that, several others beat me to it lol.

 

Welcome to TW. Good advice above. Congrats on the truck.

 

Thanks for all the quick replies and the information. THAT WAS FAST!!! Hahahaha Won't try it again then.

 

OMG, HOW COULD YOU... OMG...

 

The people who are saying don't use 4WD on dry pavement AT ALL are wrong. You can activate 4WD on dry pavement as long as you maintain a perfectly straight line. Turn it off before doing any turns.

I meet my monthly 4WD lubrication needs on a long perfectly straight road into work. I turn it on once a week for a half mile or so. It's not the full ten miles but it does the trick.
