Both later model Saab 9-5’s (2002 and on), and the 03+ Saab 9-3 feature very similarly designed wheel bearing and hub assemblies. If you suspect your Saab wheel bearing (whether it be 9-5, 9-5, or otherwise) is going bad, first check out this article [click here]. Once you’ve discovered a bad bearing or hub, and purchased the required components to do the job at eEuroparts.com, you’re ready to get the wheel in the air and start replacing parts. You will need:
A 36mm axle socket and nut (this will be different if the car has had aftermarket axles installed)
Impact tools aren’t necessary but greatly recommended
Wheel Bearing Step by Step
1. Start by raising the car and securing it on jack stands
2. Remove the brake caliper and hang it safely out of the way, be careful not to tweak the hydraulic brake hose
4. Remove the axle nut with impact. If you don’t have impact tools you will have to go through the extra steps of removing the wheel, popping the center cap out, reinstalling and putting the car on the ground, and removing the nut with a very large breaker bar.
5. Disconnect the lower ball joint
6. With the spindle free, pull the axle out of the hub to allow clearance to reach the bolts
7. Remove the 3 E18 inverted torx bolts and pop the hub out of the spindle
8. Apply a small amount of high temperature anti-seize to all the surfaces that will see metal to metal contact, either with the spindle or the brake rotor
9. It is recommended to use new hub bolts, and torque value is 90 Nm +45°(66 ft. lbs. +45°)
10. Clean and install the brake disc, ensuring it is free from grease, replace the set screw
11. Reinstall the brake caliper, torque value is 140 Nm + 45°(103 ft. lbs. + 45°) for the Saab 9-5 and 210 Nm +30°(155 ft. lbs. +30°) for the Saab 9-3
12. It’s recommended to use a new axle nut, reinstall but don’t torque down yet
13. Install the wheel without the center cap, and lower the car to the ground
14. Torque the axle nut to 230 Nm (170 ft. lbs.)
15. Install the lug bolts to 110 Nm (81 ft. lbs.) and install the center cap back into the wheel.
That’s all it takes to enjoy a refreshed, smooth, quiet ride. Generally a wheel bearing can last over 200k miles, but depending on what stress the bearing has been put under, whether or not the axle has been replaced and torqued correctly, as well as other circumstances will factor in to the life of your wheel bearing.
