Title: Bearing noise
Post by: danzigfan on 07 August 2016, 06:59:30
Hi guys, yesterday I replaced both front bearings - I was certain that was the cause of typical failing bearing noise BUT no...There is still bearing noise coming from somewhere. When I try to find where it comes from it doesn't sound like rear wheel bearing at all - the noise/grinding is constant from the move. It's deep sound like an aggressive tyre tread from under the car and doesn't vary when taking corner. It gets oversounded by the wind/tyre noise when driving faster.
A member gave me an idea it could be diff bearing or a diff itself.....Never had this problem before, how can I test it?
Thanks in advance, Stan

I jacked up a rear end of the car today and it seems that diff pinion seal is knackered - there is oil around propshaft and diff.
Would it make any difference if I replace the oil in diff tommorow? I'm just guessing but there must be low level oil in the diff :-\ Fastest solution to try for now

A bad bearing should alter with taking corners (when you load up the suspension of the bad bearing).

Try slaloming the steering on a quiet road with no one around obviously! And seeing if the noise changes.

As for the diff I think they all do that. I checked mine and it was still full even though the leak looked bad. But no harm checking  :y

The noise is constant,  no differene when cornering....that's why I suspect diff. I'll replace the oil in it tommorow anyway just to be shure.
Thanks Webby

 I think that's more likely mate. Plus check tyres and tyre pressures. My mates Megan's had an awful bearing noise......that turned out to be shit tyres!  ;D

Have you checked the bearings for play?

No play in it but the tyres?... Well that could be the cause as well, I bought them second hand last year....I'll find out in October when I have to put winter tyres on I guess
