A lot of that is probly due to the front end binding due to it actually getting too much traction. The left and right axels are trien to turn at the same rate over different distances they are travelling. The outside tire travels farther than the inside tire. My truck doesn't make touch pavement in 4x4.

 

Double post on app

 

Thanks. I think you raise an interesting point. Perhaps I should rethink when/how I go into 4H or 4L. Perhaps I just don't need to use it unless I get stuck.

However, regarding the wheels trying to spin at different speeds - shouldn't the front and rear diffs take care of that? Again, I'm not too knowledgeable on the topic. I thought the diffs were there to allow either side to spin at different speeds so you don't get understeer. Does throwing it into 4H or 4L lock the diff? I thought throwing it into either of those modes would send power to all 4 wheels without locking the diff unless you had a locking diff.

Pardon my ignorance if I'm missing something very obvious here.

Thanks again.

 

You never know until you ask so no worries. I have a tenth Gen truck so but Ford hasn't changed the way 4x4 works so here goes... the rear end functions as it does in 2wd even in 4wd unless a locker is engaged. The front differential however engages the front right axel and tire until slipping occurs then it will engage the opposite tire. 4x4 on any vehicle not equipped with a front traction aid will only engage 3 wheels at any one time. I'm thinking when you turn giving it gas the front outside tire is being percieving as it slipping and shifts power to the inside. Our trucks are shift on the fly so I use 4wd when going in a straight line on asphalt but doable it for turns.

 

When you turn the truck, the front wheels and real wheels travel differing distances; the front wheels and rear wheels do not follow exactly the same path.

So, although your diffs will account for differences between wheels on the same axle, they don't account for differences between axles. For that, you would need a center diff. These trucks don't have center diffs.

Thus, you need to use 4wd only on surfaces that allow for some slip in the drive lines, e.g., mud or gravel.

 

Yes the hammer trick worked. Maybe it was the pretty girl sitting in the front seat clicking the switch back and forth. 4WD again You guys rock.

 

Glad to hear it

 

haven problems with my 2003 4x4 will not work checked all fuses all good no lights and do not hear any relays turn on any ? thanks
