Diff problem

[rrank badyin]

While investigating other noises, I became aware that the diff was noisy, sometime ago I lost oil, which had sprayed up onto the body above the diff.
Has anyone added oil to their diff
Would welcome any help with this

Hi Hugh, I've topped up my rear diff before, it was a bit of a pain because there is a chassis rail about 1" from the filler plug and as a result getting the new fluid in is a bit tricky, worth doing though, good luck.
cheers.....Tony..

Make sure that you top up with the correct oil. I have been told that the oil for the limited slip diff is different to that for standard diffs. I think all V8's had the LSD but it was an option on other S series cars. There has been post on here telling you how to tell if you have a LSD if youre not sure.

I've just put an lsd in mine, so have a spare non lsd diff, for not alot of money, £35 +carriage, say £30,or would meet anywhere between Bath and Brecon, if you should need it.
Can advise on fitting too, if required.
Not too difficult a job, provided you have a trolley jack and some big spanners.
Don't mix lsd oil with non lsd oil; it goes solid apparently.

I'm about to fit an lsd to a diff (4.27:1 for competition)I've just purchased - what oil does it require?

thanks tozerman,tonups2 and v6addict for your prompt responces. the problem due to a vivid imagination but i now know where the filler is and what to put in it once i have freed it off. this was my first post on s forum and i am impressed. thanks again hugh

Just pinching this thread for a quick question - what type of LSD do you need for the S3 to replace the standard diff, where do I get one, how much & how easy are they to fit yourself?

Cheers

Hi Jaye

the old shape Granada 24v and the original 3 door Cossy have an LSD (viscous)that fits (just change the whole diff as it is the same ratio 3.64:1) but any lsd for the ford 7 1/2" diff will be ok
- quaife - plate etc. but these are much mere expensive

Thanks Mick - I'll keep my eye out for one

Another project for the winter I feel - the list does grow

Cheers

Can I pick your brains a little more on LSD's please ?
Been looking on Ebay and they seem to come in 7 or 7 half inch and flanged or push in shafts ?
So is the & half inch flanged unit the one to go for or does the 7 inch fit?
One more question, were Sierra XR4x4 fitted with LSD and would that one be any good and finally some seem to be 3.62 (original 3.64)but can't see that making a huge difference even to speedo reading ?
Any advice gratefully recieved.
