Yes, the procedure shown here http://www.therangerstation.com/Magazine/Apr04/offroad.htm will absolutely work even though your vacuum system is broken.

Ah, ok. That is fairly common with the PVH system. Here are a couple of things you can do instead of permantly locking them.

So what are the positives and negatives of fixing my hubs rather than permanently locking them?

You get to maintain your current fuel economy. With hubs locked you can expect to lose about 2-3mpg (atleast thats what I lose with the hubs locked).

Thanks, I'm gonna lock them for now untill I can get some avm ones

Save the money, just do the mod in the second link I listed. I've had mine like that now for almost 2 years, with no problems yet.

You won't lose 3 mpg... I only lose about 1.5 mpg with my hubs locked in and they have full ujointed shafts, not CV's... I say you lose less than 1 mpg... Just permalock them...
