Hi chaps my sport tdv6 2005 has got a whine coming from the front diff, is there any soloution to quiten it down? new oil? or thicker oil?
many thanks

New bearings or a new diff

As a guide I replaced my 2008 TDV8 front diff with a rebuilt (and guaranteed) one through my local Indie in April 2017 - cost £830  Robin

I have been suffering from a whine/drone for months. Starts around 35mph and stays whether accelerating or maintaining constant speed, not very noticeable when decelerating. It dissappears when you go into neutral and sound doesn't change when cornering.

Do actually have a rebuild kit sat in the lounge waiting for a time me and my mechanic friend can use his garage with lifts. But not sure if I can wait that long any more... It's even starting to annoy the Mrs now.

Has any one had a quote to have the diff rebuilt?

Disco Mike i understand its a huge job, any insight into the time it takes?

Regarding the rebuild, I've dug out my invoice and the cost of the rebuilt diff was £495 plus VAT. So I guess you can expect less than that if you've already got the bits. Labour to remove and install was £171 plus VAT so I guess that was about 4 hours work?? Robin
