GC8 STi Factory with rear LSD?

[Lynx]

Did a search but couldnt find anything.

Did the GC8 v6 STi come factory with rear LSD?

My scooby seems like the rear has an open?

Cheers

whats the Gearbox code.

it wont be open. viscous as worst. an lsd if your lucky.

TY754VBAAA Trans Code

Seems like it is, one wheel spinning in the mud/gravel/Uneven surfaces

Thanks

a viscous will do that

il put $100 on an open front diff, viscous center and viscous rear. unless it was changed from factory.

How to tell if Front is open?

Oh so whats the next step? Shitty viscous!

Although a viscous unit should still bind eventually, once enough friction is applied to the fluid. Otherwise it is poked I would have thought.

look in the stickies in the GD section, one of them has a link to SDPA gearbox chart put your gb code in, look it up

they get old and worn and dont behave like they should from factory.

point to note sam - my outback.. when jacked up the rear diff is pre loaded and both spin the same way..- lsd me thinks

Funkytown you are correct.

Can these lsd be shimmed?

[funkytown]

sorry nfi. ;D

i know the mechanical 2ways like mine (from v2 sti RA) can

talk to geartech i think it is in palmy. real good cats to deal with.

STi v6 came with a Suretrac rear LSD.

If it feels open it might be munted.

no no it says sure 'truck' ;D

the viscous mechanism is a sealed unit within the diff. you may be able to cut it open but the cost involved wouldn't be worthwhile. just my thoughts, if your serious i would speak to a gear/diff mechanic. as Funky said, talk to Geartech

[Lynx]

Thanks for the reply guys.

I will be looking at getting a secondhand diff, seems like my one is stuffed.

Anyone got one for sale?

Thanks

i know r200 viscos lsd can be shimmed . you push the viscos unit harder in.. may be able to do the same to r160 and 80. i have an r160 suretrac. awesome diff locks real solid as there's nothing to shim or adjust in them. need the right oil though. but red up on them and the do spin spider gears if one losses drive. ie Wheel spinning 1 Wheel. when my axle broke in Rear it would just spin spider gears and go no where. but when you say Wheel spin ie launch or power over etc just straight locked up . lol hard to explain. you may have suretrac

I don't get it. What was the point for me?

[WRXONP]

Im saying you may have a sure trac . may have wrong oil. like i said when mine had broke a axle it would spin spider gears. when you spin one In mud that's also spinning spiders. haven't tried mine in mud. know it locks up when its suppose to swell.

[Guest]

in mud is enough to apply load to apply the lsd operation

[WRXONP]

if its viscous like said before the heat generated when the fluid shears is suppose to lock the unit. I've had heaps of r200s where when it locks / shears there is still no lsd action. fit a shim to push the unit in harder and walla problem solved. but like i said Im not sure about r160 and 80. plus we don't know what diffyou have . the way to test a lsd is to measure the break away torque and the torque neede to keep it going. so to do this you need a torque wrench and to jack one Rear Wheel up and leave the other on ground and measure the torque that's neede to force the lsd to slip. if its easy to break away there is a problem . . .

I used castrol for both my gearbox and rear diff. Diff was a 1l black bottle. G box was a white bottle, cannot remember the exact names, but got replaced about 1 year ago.

Were these the right oil to use? I searched on here to know which oil to buy.
