Front Axle disconnect problems - Can I lock it in place?

Hello all!

I have a 91 XJ with the front axle that includes the vacuum disconnect. I'm starting to have some problems with it engaging and disengaging properly and I'd like to just eliminate it by locking it in the engaged position.

First, is this a good idea? Can I expect any repercussions from this when I drive the vehicle on the street? Will it hurt my gas mileage?

How about the Transfer case? If I lock this up, is it still okay to shift from 2 Hi to 4 Hi while rolling? Or will I grind gears now?

Lastly,.. what is the best way to lock it in place?

Thanks for your help!
Whiskey

The best way?? I replaced the axle shaft with a solid shaft from the junkyard, not sure of the year. Then I got a CAD delete kit from Warn (pretty cheap). This comes with inner and outer axle seals, and a cover plate w/ gasket to cover the hole from the CAD 'pump'. Had to pull out my carrier, but to me this is the most durable way and made sense to me.

Edit: I have seen no ill affects in doing this.

On my '84, I just used a large hoseclamp to hold the collar over. Worked great for me. I did develop a small leak on the driveshaft seal as it probably started turning more.

Yes, the simple mods work just fine.

That deal with moving the E clip worked fantastic! I did it today while I was doing my oil change and swapping out springs.

Thanks for the help!
