Check your nuts ladies and gents...
Went out for a quick drive this afternoon and after a while I noticed that something just didn't feel quite right.
Going down a straight road wiggling the steering left and right slowly I could feel the rear end moving around more than it should do!
So I drove it home steadily and low and behold, the wheel nuts on the rear offside where a bit loose. No idea how they became that way as the rest of the nuts on all the other wheels where on nice and tight.
So before you go out tonight or whatever, check your nuts and while your at it check and adjust if necessary your tyre pressures too.
