front axle disconnects

hadAjeep · Sep 27, 2004

I read a post that said a 94 axle doesn't use the vacuum disco, then what does it use? Do they have locking hubs? I did do a search on this and didn't find an answer.

They are always connected

So it just relies on the front differential to allow you to turn? Why did they get rid of the CAD?

It added weight and complexity, and was a weak point in the front drive. The original purpose was to save gas, but the savings were inconsequential.

So it relies on the differential. Does that mean you need to run a selectable locker in the front?

Why would you need a selectable locker in the front? The rear doesn't have to be selectable and it goes around turns. If the front is non-disco as a 94 is, when you go around a turn the diff simply acts like the rear and the side bearings allow the shafts to turn at different speeds. If you put a non selectable up front it will definatly chirp and probably scrub when you turn but thats the price you pay for trail performance and a cheaper locker. Just learn how to drive it and it will be fine.

It's not a problem in 2 wheel drive since the axle shafts and driveshaft are effectively disconnected at the t-case. There is some clicking with an automatic locker but it's virtually undetectable in normal driving.
