Enganging 4x4

Just had 4x4 light blink but won't engage, dealer replaced actuator assy. Under warranty.

When 4x4 is turned on is the wheels supposed to spin when turning? I also have to push the gas pedal a little harder as well...is this common?

Sorry a newbie here, any replies would be appreciated.

 

This worries me. If 4x4 is engaged you shouldn't be turning to much unless on mud/gravel that can allow for wheel spin.

Sorry if this comes across as condescending because I don't know your level of 4x4 experience, but when locked into 4x4 all wheels are trying to spin at the same speed. This makes it difficult to turn and can actually cause binding in the drivetrain if on dry pavement. Your wheels need to slip a little in order to turn.

Hope that helps, feel free to ask more questions!

 

That makes a lot of sense, Thanks!

 

You bet, welcome to TW!

 

It is hard to determine your sensitivity to "press the gas pedal a little harder". If you are going down a straight, dry, paved road I don't notice any additional power requirement, but I've been driving 4x4's for nearly 40 years so my senses may be dulled a bit as opposed to somebody who is driving one for the first time. Since you have had issues already with your actuator, you might as well swing by the dealer for them to confirm "normal".

 

Basic rules of 4wd. Only use it on slippery surfaces or while driving straight. As stated, the front and rear driveshafts turn at the same rate, and cannot vary speed to accommodate the difference in rotation needed between the front and rear axle during a turn. You can use 4H all day on any road while going straight, turning is where the issue is. Only turn in 4wd on soft or slippery surfaces that can allow wheel slippage.

 

I second this.

 

Slight technicality. It's actually the front and rear driveshafts that are locked to the same speed. Beyond that we have open diffs so we are not locked side to side even when in 4x4. The rear locker of course serves to do this in the rear and A-TRAC achieves locker like functionality in the front.

 

Who needs a locker when you make more brake dust!

 

Thanks guys!

 

Another 4x4 newbie here... How do I handle icy street turns? Should I be switching back into 2x4 for the turns? Roads have been pretty icy the last week and I've experienced the drive lash with tight turns (driveway) and 1x u-turn. Thanks!

 

OP read the manual it's all in there

 

Not really - if icy or slick that will allow the slippage needed. I avoid really sharp turns if at all possible in 4WD. Definitely read through the owners manual about engaging and using the 4WD system. Lots of good info in there.
