Hi, I wondered if anyone has any theories on this issue I'm having with my '03 Zed (GT pack, LSD & Brembo's) before I go about stripping & inspecting bits..
Symptoms are as follows;
-I'm getting an intermittent 'metallic dry whirling' noise coming from the NSR hub area.
-Noise more noticeable when travelling slowly (Potentially as there's less engine & wind noise).
-Noise levels don't get louder as wheel speed increases - which indicates this may not be wheel bearing related.
-Left foot braking while accelerating, or operating the handbrake whilst moving don't appear to stop or have an effect on the noise.
-If I coast in gear then accelerate this can provoke the noise to quieten as I accelerate, although I get a squeak as I accelerate. Sometimes the noise does persist though.
-Turning right can provoke the noise to start or get louder. (My Z has an LSD. The NSR wheel is the outside wheel when turning right, therefore noise gets louder when the wheel/hub assembly is under more strain from the LSD as it's trying to take the larger turning circumference.
-I get 'pinging' & 'clicking' noises, although I think this may be a separate 'axle clicking' related issue (Which I plan to fix at the same time..).
-I've jacked up the car and can't feel any play in the wheel bearing.
I have two theories;
1-Wheel bearing. I believe the pinging noise, and the fact that turning right provokes the noise are signs of this?
2-In my eyes the more likely cause - Handbrake shoes not returning properly, and therefore rubbing. This would explain the dry sounding whirling noise, and the squeak I get as I accelerate as adding power forces the brake shoes to break free from contacting the inside of the disc? I just don't know why turning right would have such a bit influence in the noise if the handbrake were the issue?
Sorry this is a hard post to reply to without hearing that dreaded noise in person..! Thanks in advance for anyone that could shed some light on this
Am I wrong to have ruled out that I could be the Driveshaft or Diff?
