Whining diff . . . . .

[paulj]

I've just come back from a great track evening at donnington park. It was awesome....

but,

as I pulled out the circuit to go home I noticed that there was a whining noise coming from the diff area whenever I was coasting, as soon as power was applied it stopped.

Its not the gearbox as this happens both in and out of gear.

Anybody know what this might be ? Is it something I can repair or replace myself ?

Thanks

Paul.

Its a 1994 Chimaera 4.3 by the way!

Could be the wheel bearings - does the noise change on bends?

A lot of older Chimaeras and Griffs are needing diff rebuilds now - mine was done last year and if you do a search you'll find a load more. Unless you're a pretty competent home mechanic type I'd leave it to a specialist.

Check there is oil in it - if you can reach the filler.

Exactly what happened to my 1992 Griffith. It got worse and worse. I fear you're eventually going to be in for a recon unit.

How much can expect this to cost me ??

That's worth a thread on its own but I think the chap who bought mine spent £7-800. It will vary a lot on where you go, ie main dealer or grimy-handed genius in shed!

Is it still whining now its cooler, because I thought 'they all do that' when very hot and have had a hard day at the office i.e. been on a track day .

Hi Paul,

I had this exact same problem a couple of months back. At first I though it was just a noise I'd never heard before but had always been there. But over the course of a couple of weeks it got louder. It sounded a bit like the noise you get when in reverse, or an Austin Metro gearbox makes all the time!!

Turned out to be the bearing on the diff. I got Top Cats in Aylesbury to replace them, cost about £500.

Hope you get it sorted
