Diffs

[rossco]

I have just had a £800 bill to rebuild a the diff for my 94 chim. It was bought with only 29k (6k miles ago) on the clock. I have also has to replace both rear wheel bearings. Is this normal or have i been sold a car with an potencially incorreect mileage?

Sounds like the previous owner had a passion for Santa Pod race day syndrome to me. I know its a powerful car but a diff and bearings should last longer than that

I've got a 97 Griff 500 with 35k on the clock. I've just had my rear wheel bearings done however there is still a droning noise so think the diff will need looking at soon...

Where did you get yours done?

[rossco]

Does the droning noise start from very low speeds? I had mine done in Aberdeen which is probably of very little use to you. However, one owrd of advice is to fine a garage with low labour rates, as it is extremely labour intensive. The usual TVR engineering problrms where you need 4 arms to lift the diff out and everything had to be removed from the gearbox back.

the job itself is relatively easy just time consuming so a TVR dealer is probably not necessary. I would even have trid to do it myself if I had all the kit.

The parts alone are £325 plus vat.

Similar problem - My 96 chim 500 is approaching 50k miles. I've been told my 'noise' is both rear bearings. I've done one side but the noise still persists, but has reduced. Am hoping that the cure rest with completing the job.

Fingers crossed that the diff doesn't need doing.

Not really sure when the noise starts...my exhaust kinda over powers everything at low speeds.

I can certainly hear it at about 40mph. If /when I get it done I'll probably go to Thames Valley Racetech which is near me, Im in Reading. I've spent a fair whack of money on it lately so am lothed to spend much more at the moment!

Cheers,

Graham
