LSD

[nolc]

Can you tell if an LSD is fitted without taking it out and looking ?Local lad scrapping a 6 cylinder 2.0 reckons it has one fitted.

spinning the back wheel when its jacked up is the best sighn if the other wheel spins in the opposite direction then you have lsd..........i thing someone may need to back me up on this one

[Theo]

Yup - easiest way is to jack the car up on the diff so both rear wheels are of the ground (remember to chock the front wheels) Have the car out of gear with the handbrake off, spin one of the rear wheels, of the other one spins in the same direction - it is an LSD!

[nolc]

Im thinking same as you,just better to ask

Both wheels should spin the same way with a Lsd

same direction

[Theo]

When I posted the 'yup' was in response to the initial post, not the advice from the first chap!

[nolc]

Thanks for that

[DJ_B4L]

so if they spin in the same direction this its a LSD?

or if they spin different ways then its a LSD

which one?

[Speedtouch]

Same direction = LSD

Opposite direction = Open

[DJ_B4L]

thanks for that

2 thick black lines lef ton the road behind u is the easy way to find out

[Douzeper]

Would jacking one side up and trying to spin the wheel by hand not give you the same conclusion?

Doesnt spin by hand - LSD

Does spin - open

[cliffybabe]

no cos u cant see if both wheels spin the same way

[Douzeper]

Yer probably right but..... if it was LSD it wouldnt spin? if it was open it would?

No?

[jpboost]

Douzeper's right,

If the car's got a slipper, and you only jack one wheel, then it's difficult to turn. as it's pretty much linked to the other wheel that's not moving. Not impossible to turn though, I can turn mine (just) by hand. I think they can get easier to turn as the diff wears. Mine's rebuilt less than 5k ago FWIW.

[Speedtouch]

Can't you just fill an open diff with thick grease to get the LSD effect?

[H35-IAN]

hehehee just put it on full lock and drop it at about 4k rpm lol if u can do rings u got a slipper if u start spinning just a wheel its a homo diff!!
so be carefull in this weather either can be good fun tbh but lsd pisses on homo open diffs!

homo diff

not a def there either
ive left 2 lines with an open diff

quite a few at lakeside can confirm that

think booty blaimed some chavs in a nova after me and karan pratting about

[Globulator]

'ss easy. An LSD links the two wheels together.

Stick car in neutral
Disengage handbrake
Retrieve car
Chock front wheels
Disengage handbrake, check for neuttral.

Jack up ONE read wheel.

If it is very difficult to turn you've got an LSD - as it's trying to turn the other wheel
If it moves pretty easily you haven't, as propshaft just spins.

[clubfx2]

Nice response cliffy, that's how i'd check it tooo....

yes sounds right or u could just toe and heel it n find out if both wheels light up or spin her round see if it goes round easy enough as u can normaly tell if u try and donut as it will push on or you can hear 1 wheel spin

[yz_250]

Normaly only the 325is,M3 and the 333i got lsd and 318is was optinal lsd but other then that the other e30 was open saw it when i did some resurch on lsd a wail back !
