4x4 in the first 1,000 miles?

Hey Everyone,
I read the break-in “rules and recommendations” about not towing etc and was curious to know if you could use 4Hi in the first 1,000 miles? I have never had a 4x4 before, so this might be a noob question. Thanks in advance!

 

Yes you can use 4x4. It is recommended that you put it in 4wd for at least 10 miles a month just to keep everything lubed and working. Go find some dirt and exercise it. If no dirt.... find a nice long stretch of pavement. Be careful turning on pavement in 4wd as the steering can bind up on to sharp of a turn.

 

As stated above, I personally would recommend using it as part of the break in process.

 

Why can’t you tow with a new truck?

 

You can, but it is not recommended.

 

But why?

What is different about a new truck vs one with 100,000 miles?

Geniune question.

 

I took mine off road on the way home from the dealer. It is not recommended that you use 4x4 on pavement so find some dirt or depending on where you live snow.

There was a tread a while back about this same subject. I'll see if I can find it for you.

 

New trucks have new ring and pinion gears, which haven't fully mated with one another. It's during this break-in period that the gears mesh through heat cycles and a small amount of wear. The manufacturer recommends you not tow while all of this is going on, because it exacerbates the generation of heat which can damage the fluid and/or gears.

 

The engine and drive train should have some milage on it before putting it under that kind of stress. Best I can give you..... I personally feel as you do. Use the truck for it's intended purpose right off the lot if you need to. Shouldn't hurt anything.
I used to break in my vehicles by going on a long trip and getting it up to 100 as frequently as possible and never drop below 80.

Fixed.
Let's not go through this again

 

I used it in the first 5 miles! It's made for it. Be gentle but use it all!

 

need more coffee.

 

I understand older vehicles required special brake in procedures but didn’t think that applied to modern vehicles.

If I used my truck aggressively right away I may change some fluids early but brand new shouldn’t work less well than old.

 

Bedding the brakes. Light duty cycles to begin with.
Every machine is like this.

 

Thanks, I appreciate the info. The Northeast where I live got some snow and was curious if I could use it or not for the first time. The roads were wet, some slightly slush and chunk covered. I was easy with it as first time use. Thank you!

Thanks! I appreciate the info.

Thank you, I appreciate the info.

Thank you, I appreciate the info. I will have to read through the thread.
