Hi

My rear diff seems to be banging and clunking recently, I've heard changing the oil can help this?!?

What sort of oil do I replace it with?

I've topped it up with hypoid 80/90, but speaking to a mechanic friend, he said to put in a Lucas oil?

Any ideas?

Thanks

Is it cracking and whining too?

The rear axel is fitted with a LSD and needs LSD specific oil to enable for it to operate correctly :!:
Putting in hypoid 80/90 is a NO NO :adminfinger
Hopefully not to much damage has been done :fingersx
Drain the differential and refill with a LSD oil such as Comma http://www.commaoil.com/passenger-vehic ... s/view/195 which is sold in many auto factors or posted from ebay or from here but they are expensive http://www.smithandallan.com/prodpage.aspx?id=1867
Get 2 litres as the diff holds about 1.2 litres and should be changed every 36,000 miles/3 years or sooner if towing or used off-road

It would be worth dropping your back plate off when you drain it ....

Look at my ****** diff:

Hi,

Thanks for all your advice, replaced the oil with the comma oil! Made a difference straight away! You may have saved my diff.

Cheers guys!

maybe for piece of mind drop it out again after 4/6 weeks and any **** left inside will come out with new oil.
then fill with new again, after all its cheap enough and a quick job :thumbleft:

Agree as these diff oils rarely get changed at the correct periods and it can only do some good for sure :thumbright:

Hi

My diff is now whining a lot, is it going to let me down?

Did you open up the casing?

No tbh just drained the old oil, there was a few iron filings on the bung, and replaced it with the new oil!

 

[eddmurphy]

I'd be fetching the back plate off and inspecting it....

 

[wozizname]

I've drained mine a few times and found some iron filings on the magnetic bung from time to time due to working the truck hard, very hard
For the price of £10-15 for the oil I'd drop it out and see what's on the magnet again and at least you know you've flushed through the LSD friction plates :wink:
What have got to loose :fingersx
