Hi, I recently became the owner of a 1974 914 1.8. The car has been checked over by a UK Porsche specialist and been found to be mechanically sound but there is an intermittent strange whirring/rubbing noise that comes from the rear.
I say intermittent as the noise only appears after 20 mins or so of driving and stops when driving under 25mph and returns again when driven over 30mph. The noise doesn't get any worse with speed, in fact it appears to get better but that maybe due to being drowned out. The mechanic could find nothing wrong. Does anybody have an idea of what could be wrong or how to identify the problem? Many thanks. |

OK, so assuming it is the rear wheel bearings, how tough of a job is that? Is there a "DIY How to" somewhere? I did a search on the list of articles but did not turn up anything there.
Thank you |

Thank you Yup, you can do it yourself. It's no easy task to do correctly though. CV axels have to be pulled which means new gaskets and re-packing those while your at it. Lots of write ups on 914/911 Rear bearing replacement. Good tip: Stick those new bearings in the freezer the night before the job. (IMG:style_emoticons/default/wink.gif) |
