Are you talking about the front driveshaft? You don't have to remove and of the crossmembers or anything on the petrol version. I would assume it's similar for the CRD. All you need to do is remove the 6 bolts on each end of the shaft and the shaft comes out.

The CV boot on the front driveshaft? That's what I'm referring to.

In order to do that, you need to remove the entire front driveshaft. It's not a hard procedure. Once the shaft is off, remove the joint, and replace with something like this:
Jeep Front Driveshaft CV Joint Kit: Driveshaft Parts
There's a How-to on the forum somewhere for doing this. Try using the search!

So the CV axle? That's not a driveshaft!
The fellow above posted a couple of threads for replacing the axle. You can't JUST replace the boot on these axles. You need (and should) get a new replacement axle.
I think the exact term is : cv boots. Look at this picture : ImageShack ® - photo en ligne et hébergement de vidéos.

Please refer to my post earlier in the thread. I probably does not make sense to replace just the boot -- if you can install a remanufactured half-shaft (with inner and outer CV boots already in place) that would be ideal. If you want to try and seal up your existing boot I have had good luck with black RTV sealant.

There is nothing wrong with replacing just the boot if the race/cage and bearings are fine.... the difficulty is you won't know what shape they are in until you remove and inspect. I've done it twice. CV's are still going strong.

From the factory service manual:
It looks like the outer boot (nearest the hub) from your picture so below are instructions from the FSM.
REMOVAL
(1) Clamp shaft in a vise (with soft jaws) and support
C/V joint.
(2) Remove clamps with a cut-off wheel or grinder
(Fig. 4).
CAUTION: Do not damage C/V housing or half
shaft.
(3) Slide the boot down the shaft.
(4) Remove lubricant to expose the C/V joint snap
ring.
(5) Spread snap ring and slide the joint off the
shaft (Fig. 5).
(6) Slide boot off the shaft and discard old boot.
(7) Mark alignment marks on the inner race/hub,
bearing cage and housing with dabs of paint (Fig. 6).
(8) Clamp C/V joint in a vertical position in a soft
jawed vise.
(9) Press down one side of the bearing cage to gain
access to the ball at the opposite side.
(10) Remove ball from the bearing cage (Fig. 7).
(11) Repeat step above until all six balls are
removed from the bearing cage.
(12) Lift cage and inner race upward and out from
the housing (Fig. 8).
(13) Turn inner race 90° in the cage and rotate the
inner race/hub out of the cage (Fig. 9).
INSTALLATION
NOTE: If C/V joint is worn, replace entire C/V joint
and boot.
(1) Apply a light coat of grease to the C/V joint
components before assembling them.
(2) Align the inner race, cage and housing according
to the alignment reference marks.
(3) Insert the inner race into the cage (Fig. 10) and
rotate race into the cage.
(4) Rotate the inner race/hub in the cage (Fig. 11).
(5) Insert cage into the housing (Fig. 12). Rotate
the cage 90° into the housing (Fig. 13).
(6) Apply the lubricant included with the replacement
boot to the ball races. Spread the lubricant
equally between all the races.
(7) Tilt inner race/hub and cage and install the
balls (Fig. 14).
(8) Place new clamps onto new boot and slide boot
onto the shaft to it’s original position.
(9) Apply the rest of lubricant to the C/V joint and
boot.
(10) Install the joint onto the shaft. Push the joint
onto the shaft until the snap ring seats in the groove
(Fig. 15). Pull on the joint to verify the span ring has
engaged.
(11) Position the boot on the joint in it’s original
position. Ensure that the boot is not twisted and
remove any excess air.
(12) Secure both boot clamps (Fig. 16) with Clamp
Installer C-4975A. Place tool on clamp bridge and
tighten tool until the jaws of the toll are closed.
