Hello all, went for a nice drive up on the moors today, driving back I noticed that the steering wheel was wobbling, not shaking but gently moving left and right. This from about 20/25 mph up to 50mph but getting worse with speed. This is as fast as I went. Checked over the wheels when I got home but can’t see anything wrong, no weights missing from the front wheels but there is one missing from the rear near side. Is there a slim chance that this would cause this to happen. It is bad enough for me to not feel comfortable driving the car. Here’s thanking in advance.
