The adjuster has a c-clip on it that needs to be removed before it will come off. Other than that, spray all bolts and splined ends with PB Blaster (not WD-40) first, then just take 'em apart. I'm assuming you have a 87-95 Pathfinder? The 96-ups have struts, no torsion bars.
Loosen tension on the adjusters after jacking up and supporting the front end, then take 'er apart. It's about as simple as it looks. The adjusters will come out of the crossmember pretty easily if you wrangle them around a little.
