Zoom and Print Options

Visually inspect the front suspension upper link rubber bushing (Figure 1, 1) on all four upper links for damaged bushings. Confirm wear as shown in Figures 2-5:

Wear may entail:

Zoom and Print Options

^ The rubber is clearly cracked, as in Figure 2.

Zoom and Print Options

^ The bushing insert is displaced due to a complete rip in the bushing, as shown in Figures 3 and 4.

Zoom and Print Options

^ At any stage of deterioration the link is always captured and will not result in reduced vehicle stability.

^ The bushing insert has a hairline crack in the surface, as shown between the green lines in Figure 5.

A hairline crack in the surface (as shown in Figure 5) does not require the bushing to be replaced.

If the rubber is clearly cracked (as shown in Figure 2) or the bushing insert is displaced (as shown in Figures 3 and 4), replace all four rubber bushings (Figure 1, 1) with part 8D0 407 515 C on all upper links as per the Upper Link Bushing Replacement instructions below and in ElsaWeb.

Upper Link Bushing Replacement

1. Remove front and rear links from the vehicle on both sides as described in the ElsaWeb Repair Manual, under 40 Front suspension >> Upper link, removing and installing. Follow proper predecessor repair procedure.

Carefully remove the link ball joint from the wheel bearing housing to avoid damaging the linkage stubs so the links may be reused.

2. Once the links are removed from the vehicle, hold the link in a vice with protective jaw covers. Assemble the 3348 and 3301 tools as shown in Figure 6, and tighten nut until the bushing is pressed out.

3. Place and align the new bushing in the link as shown in Figure 7 with the cutouts (see arrows) placed and aligned in the link according to Angle A. This angle must be 90° +/- 1°.

Improper alignment of the bushing may cause premature wear and failure of this bushing.

4. Press the bushing into place, assemble the 3348 and 3301 tools as shown in Figure 8 and tighten the nut until the bushing is pressed into place.

5. Reinstall the front and rear links on both sides from the vehicle as described in the ElsaWeb Repair Manual.
