Hi all
Has anyone got pix of the above rear diffs?
I bought a rear diff that's supposed to be a plated diff,but i am not sure what i should be looking for in there.
I've removed the rear plate .
Also what does a vlsd look like with rear cover removed?
Thanx
Chris

Hi,thanx 4 the pix,has the left one been cut open or do they come like that?
What is it off? The vlsd,where is the viscous coupling?near the crown wheel?
Is the housing(round part) bigger in the vlsd than in the open.
Will post a pic of mine soon

One on the left is a standard open diff, that is what they look like when you crack the rear cover.

a plated clutch has a very distinctive 2 plates inbetween them..unlike the vlsd where it looks enclosed (as it is for the oil) the plate lsd has very visible clutch plates in it that sit in the middle

Here's a couple of pix of my "plated lsd"
What do you guys think?

that looks like a clutch pack to me but i cant see inside

vhte viscuc LSD tend to have a completely sealed section inside the housing..this is where the high viscosity oil is housed between the plates

That looks just like the insides of my one (clutch pack from an RX turbo Leone).
I havn't seen the inside of a VLSD one before.

It looks like VLSD, but could be clutch pack LSD as I havent seen/opened up CLSD.
Another thing to ask - pull out the RHS drive shaft, it will be hard but will pop out, what does the end look like?
Do you know any history of it ie. where and which car is it off from?

Oh another thing - I'm against to open the LSD centre up because once you do it wont be the same again. Get the pros do it.

its got late model wrx "male" cv's on it,so its the long one on the drives side.
Still confused ,it looks a lot like the vlsd in the earlier pix

Wouldn't this be an open diff because it still has spider gears? I've got one exactly the same here and when I rotate one side the opposite side rotates in the opposite direction.

PeeJay · Post by **PeeJay** » Wed Nov 28, 2007 9:12 pm

But it can't be an LSD, you can see the gears through the hole, identical to mine. Unless there is something I'm missing? Mine was supposed to be a VLSD as well.

a viscus LSD has no visible spider gears

the viscus coupling is several plates inside a sealed area that has a very high viscosity oil. hence the nam VLSD

a clutch pack still has a couple of gears visible in the centre but has different forms and different ways in which the clutch plates work..come hav eplain simple clutch plates in place of the spider gears, but most have several gears there which are joined by a clutch system to even out the load and provede the limited effect....ill try find the photos of mine somewhere caus i have had both viscus and clutch pack...IE: my current wrx diff is a clutch pack that i have had repacked and its highly visible clutch packs in there as well as gears(sspider gears) in the centre...and my liberty had a VLSD...which had a closed of secion for the oil and plates
