Pulling to the left, excessive tyre wear, replacement exhaust, front suspension bushes, central locking on drivers side, replacement of steel water pipes.
Water ingress in nearside, cured by replacing pollen filter and reseating seal.
After many attempts to cure the "pulling" problem, I have given up and will live with the problem until I sell the car.
I will not buy another Mondeo.
Have you tried realigning the subframe to cure the pulling to the left. About £80 from a Ford dealer, I bet that's all it is.
Its the best car I've owned every thing needs tender loving care
