Different wheel bearing housing versions with and without bushings

Wheel bearing housings with bushings are being introduced as of Model Year 2002 to provide optimum sealing of lower link bushes (track control link and guide link).

• ◆ Assignment => Parts List

• ‒ Wheel bearing housings with no bushings (old version) for wheel bearing ø 75 mm and ø 82 mm
• ‒ Wheel bearing housings with bushings (new version) for wheel bearing ø 75 mm and ø 82 mm

• ◆ A combination of wheel bearing housings with and without bushings is permitted.

• ◆ When installing wheel bearing housings with bushings, use is also to be made of the corresponding track control links (new type) and track control link/guide link fastening elements.

• Flange nuts are to be replaced by combi nuts as fastening elements.
• Guide links need not be replaced.

• ◆ Conventional flange nuts are to be fitted for vehicles with wheel bearing housings with no bushings and old type track control links.
• ◆ Bushings are not intended to be replaced. If damaged, replace wheel bearing housing.

Removing

• ‒ → Detach wheel trim. In the case of light alloy wheels, use puller from vehicle tool kit or suction grip -3208- to remove trim cap.
• ‒ Slacken off hexagon bolt for outer joint of drive shaft by max. 90° (vehicle must be standing on its wheels to avoid danger of accidents).
• ‒ Raise vehicle and screw out hexagon bolt for outer joint of drive shaft.
• ‒ Remove wheel.
• ‒ Secure brake disc with wheel bolt.
• ‒ Pull wire of ABS speed sensor out of holder at wheel bearing housing/brake caliper.

Vehicles with brake caliper HP-2

• ‒ → Screw out hexagon bolt -2- and detach brake pipe holder.
• ‒ Unscrew bolts -1- for brake caliper and detach brake caliper.
• ‒ Re-attach brake pipe holder. Screw in and tighten hexagon bolt -2-.
• ‒ Attach brake caliper to body such that its weight cannot bend or damage brake pipe.

All vehicles (continued)

• ‒ → Unscrew bolts -1- for brake caliper.
• ‒ Detach brake caliper and attach to body such that its weight cannot strain or damage brake hose/brake pipe.
• ‒ Detach brake disc.

• ‒ → Unscrew bolts -1- for splash plate.
• ‒ Pull ABS speed sensor out of wheel bearing housing.
• ‒ Unfasten nuts -2- and -3-.

• ‒ → Pull out rubber grommet -1- and unplug connector -2-.
• ‒ Pull wire of ABS speed sensor out of holders -arrows-.
• ‒ Guide wire through openings in wheel bearing housing and take out.

• Take care not to damage rubber grommet.

• ‒ → Unscrew hexagon bolt -3- and nut -4-.
• ‒ Pull out track rod end.
• ‒ Unscrew nut from joint pin of guide link.

• If necessary, support joint pin with 4 mm Allen key.

• ‒ → Press joint pin of guide link off taper seat.

Notes:

• ◆ Take care not to damage boot when doing so.
• ◆ Insert leather cloth to prevent boot damage.
• ◆ If applicable, pay attention to headlight range control .

• ‒ → Press joint pin of track control link off taper seat.

Note:

For safety reasons, screw collared nut back on again at joint pin of track control link approx. 4 turns.

• ‒ → Unscrew nut -1-, take out hexagon bolt and lift out both links -2-.

If hexagon bolt cannot be removed from wheel bearing housing, bolt and links must be pressed out of wheel bearing housing.

Slots in wheel bearing housing are never to be widened using a chisel or the like.

• ‒ Swivel wheel bearing housing aside in direction of arrow and in doing so pull drive shaft journal out of wheel hub.

• ‒ Unscrew nut from joint pin of track control link.
• ‒ Take out wheel bearing housing.

Installing

• ‒ Insert wheel bearing housing.
• ‒ Slip outer joint of drive shaft into wheel hub and hand-tighten new hexagon bolt.

Notes:

• ◆ New type of track control link must be used for wheel bearing housing with bushing.
• ◆ If use is made of wheel bearing housing with bushing and new type of track control link, flange nut for attaching track control and guide links is to be replaced by a combi nut.

• ‒ Insert joint pin of track control link and guide link in wheel bearing housing.

• ‒ Screw on and tighten new self-locking nuts.
• Tightening torques:
• Flange nut: 100 Nm
• Combi nut: 125 Nm

• If necessary, support joint pin with 4 mm Allen key.

• ‒ Insert both joint pins of upper links in wheel bearing housing.

• ‒ → Tighten new self-locking nuts -1- to 40 Nm.
• ‒ Press down upper links as far as possible whilst screwing on.
• ‒ Fit track rod.
• ‒ Screw on new self-locking nut -4- and tighten.
