    Default Quaife Limited-slip Differential: how much noise is normal?

    I've got a Quaife limited-slip diff on my '07 Caterham and worry about the amount of noise that's coming from it.

    Do any of you guys have that diff and could tell me what living with yours is like?

    I have one installed in the Ford Sierra diff in my Westfield. I can hear it (not surprising given that it's 6" from my elbow) but it's nothing that really sticks out in my mind.

    What kind of noise does yours make and when does it do it?

    It whines under load at speed greater than about 30 mph.

    I have a video that has a good example of the sound.

    All the time or just while cornering?

    My car is in the shop of a guy who's supposed to be nth local diff genius.

    He may be asking me for the phone number of a parts source for pinion bearing and related parts.

    Nobody picked up at Rockey Mountain Caterham.

    Who next best?

    John,
    In my experience, Josh responds faster to email than phone, try him at josh.robbins@rockymountaincaterham.com

    They are noisy. You will get use to it.

    I had one installed in my 2005 SV. It made a lot of noise on acceleration and deceleration. There also seemed to be too much back lash on the ring and pinion. Twice I had Nathan Down (formally of Caterham and Rocky Mountain Sports Cars) inspect and drive it and both times he said it was normal.

    I had the Quaife installed while I was building the car so I didn't have a chance to compare its noise level to the non LSD that came with the car.

    I'll echo Scannon's input....the Quaiffe makes it sound like there's too much backlash in the gearing. I had one in an Elise and it sounded the same way.

    I checked and it appears I have a ZF rear end. Whatever is is. I don't believe I have a Quaife.
