[..^ up ^..]

Inner CV boot replacement on a 1996 Saab 900SE turbo. The repair had to be done because the old boot developed a crack and started leaking grease.

Tools and supplies:

new CV boot kit: boot, clamps and grease;
32 mm (1¼") socket: hub centre nut;
17 mm socket: wheel bolts;
15 mm socket: control arm to subframe bolt;
13 mm socket: lower sway bar link nut;
11 mm open wrench: upper part of sway bar link;
10 mm Allen key: caliper bolts;
5 mm Allen key: rotor index screw;
snap ring pliers;
torque wrench;
car jack and axle stands;
breaker bar;
hammer.

	13.10.2005 Wheel removed With the car still on the ground, remove the centre cap from the wheel and loosen the hub nut using a 32 mm socket (a 1¼" will do) and a breaker bar. Loosen the wheel bolts while you're at it too (17 mm socket). Raise the car and remove the wheel.		13.10.2005 Control arm Remove the brake caliper (10 mm Allen) and rotor (5 mm Allen). Now you can choose to either separate the ball joint or unbolt the control arm from the subframe. I find the control arm to be easier.
	13.10.2005 Driveshaft Tilt the strut and pull the driveshaft out of the hub.		13.10.2005 Inner joint The inner CV joint is located right above the subframe. These grease splatters are an indication of the leaky boot.
	13.10.2005 Separated Cut the clamps and separate the shaft. It's much easier than the outer joint, this one just pulls right out.		13.10.2005 Driveshaft Looks like my old boot was held by plastic wire ties, and there wasn't much grease left.
	13.10.2005 Snap ring Remove the snap ring on top of the shaft and gently tap the tripod bearing until it comes off. It's VERY tight.		13.10.2005 Disassembled Once the bearing is removed, you can pull the boot off and wipe everything thoroughly.
	13.10.2005 Boot kit The kit comes with a new boot, two rather awkward clamps and a bag of fresh grease.		13.10.2005 Cleaning Clean the companion flange too.
	13.10.2005 Fresh grease Assemble the joint and fill it with fresh grease.		13.10.2005 Installed Pull the boot over the companion flange and crimp the clamps tightly. Refer to this guide for tightening torque for suspension bolts.
