FWD

What exactly happens after I pull the lever from 2 Hi to 4 Hi?

I understand that the front wheels now recieve power from the engine but how is this done?

Its magic.

the lever engages the sprokets for the FWD.

The movement is transmited by a large steel chain that connects both the rear and the front shafts. When you pull the lever, the front shaft connects to the large chain and there ya go [img]icon_smile_big.gif[/img]

So if I understand you then, the front drive shaft (and everything ahead of it)does not spin until I shift into 4Hi (or 4Lo) ...right?

No, it all spins when you drive just not getting power from the motor. The spin comes from the ground.

So the forward drive train is always in motion and wearing out?

its spinning but theres no powert oit, so theres not alot of wear goin on there

If you didnt want it to, you could get disconnecting hubs, and the front axle + driveshaft would never turn untill you engaged 4hi, and the hubs.

But I dont think it wears as much as you think it would.

depending on what year xl theres a front axle disconect too

Mr. MeatCleaver · 01-05-2005, 04:28 PM

Yes, but it only disconnects one side. I still dont understand why jeep put that in there.

With a XJ with front disconnect axle (it disconnects the front diff and the passenger axleshaft), the front driveshaft doesnt spin.
