Despite having over 410000 on it, it does still run very well. And being a daily, changing these things just gives me a warm and fuzzy feeling knowing its new and shouldn't fail any time soon.
Next big job will be a new rear diff housing as mine has the slightest bend in it, according to the blokes that did my last wheel alignment anyway, so will be a good chance to source a cheap one and rebuild it.
