Question LSD Diff Question

I've got myself a 94 ED Fairmont Ghia V8 and I guess Im right to assume it has LSD.

Im asking this cause I started doing a burnout to christen it and was told by mates that only one wheel was spinning!!??!
Isnt LSD suppose to move power away from the wheel losing traction to the other, hence both will spin.

I checked the tag on the diff and its a black tag with high performance stamped on it.

If theres something wrong with the diff, i can get it check out under warranty.

Thanks.

btw ill post some pics of the beast someday.

chances are its not LSD if its not spinning both wheels. But if its like the XF's then it should have a tag on that clearly has "LSD" on it.

Don't know if 94 ED Fairmont Ghia V8's were LSD but if it did come with LSD tmaybe the previous owner blew it up and replaced it with the "High Performance"

Just my 2 cents...

Cheers
Matt

I had a look at the tag on my LSD yesterday. Interestingly enough the tag is labelled "Spin Resistant Diff".

I had a good laugh wondering whether I had an LSD or a SRD

You will know If you boot It around a corner. If It just spins then It isn't LSD. If It kicks out you've got LSD.
I don't Know If LSD was standard on V8's but It was optional on ghia's as far as I know.

Just checked Redbook website and it reckons an ED Ghia V8 should have LSD as standard equipment.

BTW, i know your pain. My EF Fairmont V8 (not a ghia) didn't come with an LSD and lighting up the inside wheel every time I turn a corner sure is pissing me off!!

I have some experiece with LSD in my old ed fairmont ghia.

The LSD's have a clutch pack that wears every time you drive it. The hard one wheel spins the more force it puts on the clutch pack to get the other wheel to spin. and every time you corner the clutches are wearing. therefore after a 100,000km the clutches need replacing. These things just wear out from use.

My 2 cents

It is only a l.s.d not a locker[Detroit Locker] where they lock up if pushed with torque..Can promote big oversteer!!
But generally they should spin both esp if both wheels are of nearly the same grip..

Not sure on Ghia but manuals only had l.s.d -std
Auto was a L.s.d extra option in v8's ...

Jack car up,put "ON STANDS"& choked put auto in "N",hand brake off, turn one wheel the one on the other side should spin the same way, if spins back the other way[opposite] its an open wheeler....No lsd.... h,t.h.. Graeme...

Chances are if your car is a '94 model, the LSD is very worn. These Diffs are not a clutch pack type, but a cone-type, so they wear relatively quickly, especially if you give them a hard time. We have a pair of gravel stage rally cars (XR6 and XR8), and rebuild the diffs quite frequently (about every 2500km) to keep them within the specs we want. They do work pretty hard though. I suggest jacking the car up and putting it in neutral as previously suggested, and seeing how the wheels spin. Chances are it just needs a rebuild.

if it's says high performance on the tag, its definatly not an LSD.

I have the same tag on my Nf V8, i was also greatly disapointed to find out i didnt have an LSD.

Is it possible to just swap over the insides to make it an lsd?
