And no it isn't the rear seat passengers! :D It's sounds very low pitch and it used to get louder going round right hand corners but since I have had poly subframe bushes fitted it now seems to vibrate the whole car slightly and is louder AND goes quieter when going round corners!? :confused:

 

Any ideas boys? Wheel bearing? Diff? Shox?

 

Ivan

id vote wheel bearing or diff whine!

Yup, at a guess right rear wheel bearing, when the weight shifts it will whine more. Gradualy the bearings will grind away and fall apart under the weight becoming very loud. No idea if they are sealed units on the Z and you need a new hub or you can replace individual bearings. Never done it or looked into it.

wouident be diff!my mate had a diff that whines and its f**king loud new diff noise gone

if it does it more round right hand bends, then its prob the left bearing, as the weight gets transferred to the opposite side :)

 

jack the rear of the car up & get someone to "drive" it. listen to both sides to identify where its coming from.

yeh that what I meant lol, misread it :slap:

 

Once had to drive 150 miles to some pikey to get a hub for a prev car I had, started off ok but a bit noisy, with 4 ppl in the car and the weight shifting as I went round corners putting on more pressure it was getting louder and louder and louder.

 

I didnt think I was going to make it there! In the end had to fit it there, the old hub / bearings just fell out a load of ground up coffee beens it looked like lol. Then I kept getting attacked by his two german shepherds :O, and he was a french pikey at that!

Nice steveo. I would have thought tho' that as the wheel gets loaded it would get louder? i can hear it well over my de-catted mongoose exhaust with the stereo on.
