whats the go with holden lsd's?

[vrcalais5ltr]

hi just a question. i had a zj fair with a 351c in it 2.88lsd diff and it spun both wheels no matter what. it was the standard diff.
now i have a vr calais 5ltr. it says on the diff high performance lsd diff. it has irs if that makes a difference.
but if u put your foot down it will only spin single wheel.
therefore i cannot get a good launch off the mark as it is only putting power down through the single wheel.
I am not a hoon drag racing in the streets.
it will be going down the strip. it is my daily but i will be working it slowly up to be a street/strip car.
well to the point is the diff buggered or is it just the way these lsds are?
is it possible to get it drive both wheels constantly?
it is like driving a car with a standard diff in it.
one of the boots is busted on the cvs if you are looking at it from the back of the car it is the inside right hand side boot. (which will be fixed as soon i get money)

I would also like an answer to this as i am unsure what type of diff i have as the tag on my diff also says high performance but does this necessarily mean LSD? As its a VS Ute and i am unsure if it is a single spinner or LSD? I have a feeling that just because it says high performance doesn't mean LSD? Is it written anywhere on the car?

[vrcalais5ltr]

it says on the tag on the diff: "high performance lsd diff"
but it doesn't say what ratio it is or anything

[SENNY]

Same as my car its got the tag
usually if the car is a V8 they came stock LSD
but thats what ive been told

[SENNY]

also in the 5L the LSD's are really dogdey if they been put through abuse
they dont last very long
you prob need a new one

[88GreenVN]

it says on the tag on the diff: "high performance lsd diff"
but it doesn't say what ratio it is or anything

The build plate on the fire wall will say the ratio GU4 = 3.08 for the VN's open wheeler and probably the same for VR.

I think the LSD option was G80 from memory.

[SENNY]

i think his LSD is just gone

i have heard that these things only do single leggers unless you put your foot on the brake. even with lsds in them? just incase you dont know what i mean it will spin both if you do a foot on. i have not tryed one because it buggers the abs and 2 dont want to destroy my tyres lol

...that would be for a non LSD..

[vrcalais5ltr]

no the person that told me that had identical car 1yr newer with lsd diff in it

in which case, it was f*cked!!!

[immortality]

the Holden LSD is set fairly soft from the factory and will single peg fairly quickly when abused, especially when doing dounuts.

the solution if the LSD isn't completly rooted is to have the diff shimmed and fit a new spring in the center.

[Disturbed_vegeta]

has the oil ever been changed? mine was shit in my senator untill i first serviced it, its pretty good now and always kicks twins. put some good oil through it and see how you go.
Also to answer a few questions
1. Not all v8s came with lsds...my stato didnt.
2. stock ratio is 3.08 unless you have a 215i manual model hsv
3. if the tag says "high performace" that means peg legger...it need to have "high performance lsd" on the tag. But the tag coud be bullshit, theres a how-to that shows you how to check if you have a lsd.

and if you service the diff and its still shit....get it shimmed. that'll fix it.

cheers mate didn't even think of servicing it common sense lol should have been the first thing i thought of. when i got it the coolant looked like it hadn't been changed in about 10years or so.

me i would say you have a cracked LSD gear. I have had a couple of LSD's go like this. It will cost between 3 and 5 hundred to fix. common problem with all makes.

[vrcalais5ltr]

i will have a look when i change the oil in it on wensday

[burnz]

GU4=3.08 (normaly auto)
G80=3.45 (normaly manuel)

standard 2 pinion (open)
sandard lsd 2 pinion ( i think these were deleted)
high performance 4 pinion (open)
high performance lsd 4 pinion

hope this helps

[burnz]

the diff requires torquo additive 8 f/oz

[vrcalais5ltr]

the diff requires torquo additive 8 f/oz

cheers whats a good quality diff oil to use in these?

[SENNY]

wouldnt have a clue

[immortality]

just use a diff oil thats specifies use for LSD. i use penzzoil 80w-140 gear oil

read this, diff, all you need to know

[shiftySLE]

Get a diff guy to service it and shim it up to tighten it right up, it wont be a locker at all but wont single spin either. If it is single spinning that hard, it is just ****ed, nothing else to it. A LSD is an LSD no matter what make or model. Both wheels spin with only Limited Slip to go around corners without hopping.

Common Problem????

I have had 4 commodores with LSDs fitted. These vehicles were purchased new with LSD specified and I have never had any issues with any of the diffs.

If you have a high KM car the diff will wear like everything else and in many cases owners never bother to change the diff oil - let alone check the oil level.

Many cars are driven too hard so if you or others have abused the drive train on your car expect to have expensive problems.

[ScoHar]

Yea i think it comes down to kms and how its been used by previous owners, had a 3 LSD IRS diffs in 3 different commodores (VP-VS) and they all seem to act differently, 2 of them worked the way OP is describing, but I have had one that almost felt like a locker.

[Silver_VS_II]

i heard it sounds like you have a lsd by what it says on it but its really not

The ZOMGWTFBBQLOL how to tell if i have an LSD thread:

quite sure i read it here.

also when you say LSD diff it annoys me. wouldnt that be like saying limited slip diff(erential) diff?
