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.

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.

Looks like my old boot was held by plastic wire ties, and there wasn't much grease left.

Remove the snap ring on top of the shaft and gently tap the tripod bearing until it comes off. It's VERY tight.

Once the bearing is removed, you can pull the boot off and wipe everything thoroughly.
