- ⚠ Some states may require inspection after brake modifications
- ⚠ Never drive the vehicle until brakes are properly bled and tested
Step-by-Step Instructions
1 Gather all parts and verify fitment
Before starting, ensure you have all necessary parts. Verify that your CRV knuckles are from a 1997-2001 CRV (RD1). Check that the trailing arms or hubs match your year. Test fit wheels to ensure proper offset and clearance.
2 Remove front wheels and brake components
Lift and secure the front of the vehicle. Remove wheels, brake calipers (support with wire), and brake rotors. Disconnect the ABS sensor if equipped. Remove the castle nut and separate the ball joint from the knuckle.
3 Remove the front knuckles
Disconnect the tie rod end from the knuckle. Remove the two bolts connecting the knuckle to the strut. Carefully remove the entire knuckle assembly. Note: You may need to use penetrating oil and heat for stubborn bolts.
4 Install CRV front knuckles
Install the CRV knuckles in reverse order. Bolt the knuckle to the strut (torque to spec). Reconnect the ball joint and tie rod end. Reinstall the ABS sensor. Install your brake components (you can reuse your existing calipers and rotors with proper spacers, or upgrade to larger brakes).
5 Remove rear wheels and brake drums
Lift and secure the rear of the vehicle. Remove wheels and brake drums. If converting the rear, you'll need to either swap the entire trailing arm or press out the old hub and press in the CRV hub.
6 Install rear 5-lug hubs or trailing arms
If swapping trailing arms: Remove the four bolts connecting the trailing arm to the chassis and the bolt connecting it to the lower control arm. Install the CRV trailing arm. If pressing hubs: This requires a hydraulic press and should be done by a professional or with proper equipment.
7 Bleed the brake system
After all components are installed, bleed the brake system starting from the wheel furthest from the master cylinder (usually passenger rear). Ensure firm pedal feel before driving.
8 Install wheels and test
Install your new 5x114.3 wheels. Torque lug nuts to specification in a star pattern. Lower the vehicle and perform a test drive in a safe area. Check for any unusual noises or vibrations. Get a professional alignment immediately.
