I think i know the answer to this but dose any ony know if there is a top speed to go while in four wheel drive like on my truck it's all buttons like i have 4x4 and then low range so which one is the one that is to drive faster if you could answer that would be great..

THANX..

 

It should be in your owners manual. However, I've heard no faster than 55MPH in 4-Hi and 15MPH in 4-Lo.

Depends on the transfer case as well. I do know that 4wd trucks at dragstrips and such dont have problems when running 4wd...
As long as you dont turn in 4hi you can go as fast as you want.. [img]i/expressions/face-icon-small-happy.gif[/img] 4lo is another story. haha


But yes, Stick to those numbers.

 

Also never run a truck very far or very fast on dry pavement in 4 hi. I have driven down the road at 65 in 4 high but it was on snowy roads. The drivetrane in your truck binds up on dry pavement in 4wd and it is hard on it. I had a room mate in collage that swor there was no reason to put it in 2wd durring the winter. He never took it out of 4wd from first snow till it was obviose we where done with snow season. I told him every chance i had that he was an idiot. Suprisingly he could never figure out why he had to replace or rebuild his transfer case every year. (literaly every year.)

 

I know on my dodge the manual says not to shift into 4-hi going over 55 mph. but doesn't say anything about top speed. ive been in the 70 mph range.

 

The issue is not when going straight at higher speeds but at lower speeds when you are turning. If the surface is dry and your tires can't slip like on dirt or snow, you will get "driveline Wrap up" which can do damage to your drive shafts and transfer case. The drive line is loading and un loading causing binding which can twist parts pretty good.

Look at the sitution: If you can do 50-70 MPH, you do not need to have four wheel drive engaged
