@ For the past couple of months I’ve been experiencing a weird knocking noise from the front of my Vectra VXR. It’s been getting progressively worse recently and with the MoT looming, I feel I should try and get it sorted before it goes in. The noise seems to be from the passenger side and more prolific over speed bumps and uneven surfaces. I did let my local tyre place have a look when they changed the front tyres but they said the wishbone bushes and the track rod ends were fine. One thing I have noticed it that over rough surfaces, I can almost feel the noise through my heels. Appreciate that makes no sense but it’s difficult to explain. Hope you can shed some light and it won’t cost me a fortune! Christopher.
AThe Vectra C is prone to a few knocks and creaks as things get worn and tired and these can range from worn drop links, strut tops, ball joints, inner and outer steering joints, engine mounts and even the radiator pack mounts. The VXR with its low profile tyres tends to exaggerate noises which could be seen as a good thing as you can then resolve them before they get worse. Resolving said issues is sometimes rather challenging however.
It will either take a well trained ear on a test drive or the services of a flat ramp and a bit poking around. Despite the tyre place checking, it’s worth bearing in mind that with the wheel hanging down, certain worn parts can’t be traced, for example the top mounts as they have the weight of the wheel etc hanging on them, which can pull components tightly together and thus there’s no more play and no more noises. We wouldn’t like to guess at the cause but the upside is the Vectra, like many other Vauxhalls, is relatively easy to work on and parts aren’t ruinously expensive.
