Remove the front wheel, having first marked its position relative to the hub.
Remove the ABS sensor from the bracket (if equipped).
Remove the brake caliper and hang it on a wire (see chapter "Brake system").
Caution! Do not disconnect the brake hose, otherwise you will need to bleed the brake system later.
Unscrew the nut on the steering tip. Press out the tip using a puller (for example, Hazet 779) or Opel KM-507-B devices.
Remove the cotter pin from the hinge support, unscrew the crown nut, press out the hinge with a puller or the Ore! KM-507-C device.
Remove the hinge pin from the hub manually. If this is not possible, press it out with a puller.
Support the front pillar with a jack to prevent it from falling when releasing the top mount.
Loosen the strut mounting nut at the top with a 24 mm bent wrench, while holding the rod with a wrench with internal teeth, for example Hazet 990-Lg-12 (some variants will require the Hazet 990Lg-10 key).
Lower the rack down.
Installation
Attention! If the rack has only been removed and not repaired, before installing it, check the tightening torque (70 Nm) of the thrust bearing mount.
Insert the strut from below, put the thrust washer on top first, then the fastening nut and tighten it to a torque of 55 Nm, while holding the shock absorber rod.
For vehicles with ABS: secure the ABS sensor with the bracket with a torque of 8 Nm. Secure the wire holder to the rack.
Lubricate the axle shaft splines with transmission oil.
Insert the axle shaft into the hub.
Caution! Use a new washer and castle nut. Screw on the castle nut without tightening it.
Insert the joint into the steering knuckle and tighten the crown nut to 70 Nm. Insert a new cotter pin into the nut and bend it.
Install the steering joint and tighten the new self-locking nut to 60 Nm.
Tighten the caliper mounting bolts to the strut with a torque of 95 Nm, after cleaning their threads and covering them with Loctite 262 sealant.
On the GMF caliper: fit new protective caps onto the caliper bolts until they stop. The caps should fit evenly against the caliper.
Install the front wheel, observing the previously made markings.
Release the car.
Tighten the wheel bolts crosswise to 90 Nm.
