Citroen Removal of Wheel Bearings PDF Installation Instructions Manual

We goinstallation oftopic dedicated on with our to the wheel bearings. In this issue we will look at non-driving rear wheels, and consider two types
of bearings: – Cartridge double-row tapered-roller bearings, – Hub double-row ball bearings.

Cartridge bearings with two rows of tapered rollers are used for the non-driving rear wheels of compact and mid-size vehicles. They are usually mounted in “drum-brake hubs”, and sometimes in “disk-brake hub”. Hub bearings, also called “single-flanged bearings”, integrate the hub function in their outer ring, to which the brake rotor and the wheel are directly attached. This solution, which facilitates assembly and increases reliability, is mainly used on the non-driving rear wheels of upper mid-size vehicles. Note: The last page gives important recommendations regarding the nstallation of wheel bearings and provides a list of vehicles and kits corresponding to the two types of assemblies discussed in this document.

I. REMOVAL
1 Remove in sequence: – the brake drum or the caliper and rotor, the hub cap and the spindle nut, – the hub bearing (by hand
or with a bearing puller).
2 Before installing the new bearing, check the overall condition of the spindle and the cleanliness of all surfaces that will contact the bearing. The SNR kit contains all parts necessary for assembly. Sometime, a sheet metal slinger ring is mounted on the steering knuckle. In this case, the bearing seal should have a front lip that rides against this slinger ring. Do not remove the slinger ring.
3 If the seal has a front lip, apply a bead of grease under the latter. Install the hub bearing on the spindle either by hand or with a threaded chuck positioned at the end of the spindle.
4 With a torque wrench, tighten the new spindle nut to the torque recommended by the car manufacturer. Re-install the hub cap. Re-attach the brake drum or the rotor and caliper.

PRECAUTIONS TO TAKE WHEN INSTALLING BEARINGS
1. Always refer to the technical manual of the vehicle.
2. Prepare all necessary equipment and tools before starting installation. Make sure they are clean and in good working condition.
3. Verify the kit part number. Remove the bearing from its packing at the last moment, and always place it on a clean workbench.
4. Clean parts and components that are in the vicinity of the bearing and check they are in proper condition. Check particularly that the hub, steering knuckle and driveshaft are free of scratches, scoring or indentations. Replace any damaged parts.
5. Do not remove or damage parts that are not provided with the kit (e.g. slinger ring).
6. Never remove or separate the components of a bearing.
7. To ensure a correct bearing installation, use a press (approx. 10 tons capacity).
8. Always apply the load to the ring that is being fitted. The fitting load must never be transmitted through the rolling elements (balls, rollers). Never apply pressure to both rings at once.
9. Apply the torque values recommended by the car manufacturer.
