Hi, I have a 2010 hilux diesel d4d. The vechile has 530000 km on it and has until recently not given a days trouble. I now have a rattling noise when I pick up speed. The noise appears at 2200 rpms and then lasts for a second or two until I am past +- 2300 rpms. I have told that it is the balancing shaft. I would appreciate some advice.
Thanks
