Exclamation 4WD turning

When I put my 2011 JKU in 4WD HI or LOW, it does not want to turn easily and jerks around a ton. Is this normal? My 2004 Grand Cherokee never did this in either of the gears...
Any comments is greatly appreciated. I have a few other issues going on with the Jeep as well.. Just want to make sure it is nothing I need to worry about. Thanks

Don't do that.

Your Wrangler uses a "true" 4wd system. Once engaged, the front and rear driveshaft need to spin at the same rate and therefore won't allow for the slightly different rate at which your wheels must turn when they all have essentially perfect traction on pavement while trying to go around a corner. The resulting binding causes the "crow hopping" you experienced.

When you engage 4wd while you have normal traction (i.e., on dry or even just wet pavement) you therefore risk damaging some of your drivetrain components.

Your Wrangler's 4wd system should ONLY be used in low traction situations. Generally, that means messy offroad conditions or completely snow covered roads.

Your Cherokee had either select-trac or qaudra-trac depending on the year. More of a AWD I believe.

Totally agree with MTH. You will do damage if you use your 4WD on pavement and attempt tight turns.

Oh I've been doing that and getting banned in the process from the JK-Forums. Pretty sure I'm done with that place.

Yup. Tried to give advice there that came from other sites...blocked. Their site, their rules, but seems counterproductive to the whole Jeep experience...

As for the OP's question, like many others, all I can say is...



Oh, and Hilldweller, even though he's the proud owner of a Power Wagon, and therefore the enemy merits consideration.

What about a switchback on the trail at low speeds? Normal for it to occur there too?

If it's a real tighty, I switch to 2wd for it (if that's safe).
That front diff can bind and be a bear to swing around a tight turn. That can send you in the weeds if you're not careful sometimes.
