The front strut on every Tiguan is a load bearing part of the suspension.At the bottom it bolts to the steering knuckle. In the middle sits the coil spring that carries the weight of the car. At the top is the top mount, a rubber and metal block with a bearing inside that lets the whole strut rotate when you steer. A damper runs through the centre. Because the strut turns with the wheel, a worn top mount bearing makes noises you hear and feel through the steering.
Top mount bearings are the most common strut problem we see on Mk1 and Mk2 Tiguans in Dubai.Dust and water get past the seal, the bearing corrodes, and it starts to stick and release as you turn. You hear a creak or a knock on full lock in car parks, and the steering feels notchy. The rubber in the mount also hardens in the heat and cracks, which lets the strut move and clunk over bumps.
Coil springs break more often than people expect.Corrosion starts where the coating has been chipped by stones, and the bottom coil eventually cracks, usually close to the spring seat. The car may still drive, but that corner sits lower, the alignment changes and the broken end can cut into the tyre. We find these on the lift by checking each coil, the spring seats, the bump stops and the drop links, and by turning the steering while listening at the top mount.
Once we know the faulty part, there are two ways to fix it.A complete ready strut comes assembled with a new spring, damper, top mount and bearing, so the whole corner is renewed in one go. A rebuild keeps parts that are still good and replaces only what has failed. Either way we finish with a front alignment, because changing a strut moves the camber and toe and a Tiguan will wear its front tyres quickly if this is skipped.
