4x4 issues?
 
whats up guys...i got a problem or maybe not but anyways i got a 97 TJ automatic. well when i make a sharp right or left turn on 2WD im fine but once i shift it to 4WD and make those turns it seems like my front wheels wobble and want to break off.....so just wondering is this common or i got some problems?...thanks

That is a common issue for new Jeepers that is easily prevented from happening... never shift into 4x4 while on a paved surface. In other words, stay in 2wd when you're on the street.

The Wrangler's 4x4 system is a "part-time" system that was not designed for use on paved streets. It was designed only for use when on loose slippery surfaces. Dirt, mud, rocks, snow, or ice.

Why does it cause the steering to jerk back & forth & make it feel funny when you shift into 4x4 (4Hi or 4Lo) on the street? Because the Wrangler's 4x4 system mechanically locks the front and rear axles together so the tires on both axles must rotate at exactly the same speeds/RPMs. The problem is that when you turn left or right, the front tires must rotate faster than the rear tires and being in 4x4 prevents that from happening which is why the steering feels funny... the front tires are fighting with the rear tires.

Only Jeeps like the Liberty, Cherokee, and Grand Cherokee have optional "full time" 4x4 systems that can be used on the street.

The Wrangler's 4x4 system should not even be used on the streets when they are wet from rain. Even wet streets have too much traction for the Wrangler's part-time type of 4x4 system. :)

That's called 4wd. Your front tires are grabbing an trying to pull your vehicle as opposed to when you're in 2wd and they're just rolling free (being pushed). You should never, NEVER, run your Jeep in 4wd on dry pavement. Unless you want to hear a loud bang, some odd metallic noises, and the sound of your wallet being emptied.

Dang, Jerry types faster than me. Um, what he said.
