Fellows..

I reckon i had an LSD...the seller gave me assurance that the LSD was working okay...was surprise to see that when tested via the wheels, both were not moving in tandem...so lets set aside if he is truthful or not, what i am interested is how to move from here...can we fix it (assuming that the LSD is faulty)...how can we assure that the LSD is faulty...am i to change to a new LSD or a helical ITR LSD...what would the best choice....

 

Sorri fellas..specs are as follows:

i have a B20Vtec hybrid with a B18C1 head...exedy clutch, lighten flywheel...b18c traynny at 4.40...

 

That is not the best test, that will only work depending on what type of LSD it is.

 

Go drive it around, hard acceleration around a corner will smoke the inside wheel without LSD

 

I'm confused.... so you want to make sure the LSD still works? I'd say you'd probably have some VERY bad noises if you have an LSD and it's busted. If you want to check if a car has an LSD, jack up the testing end, and with the car in neutral, turn the wheels. The wheel you're not turning should rotate in the opposite direction.

 

Only a clutch type LSD will cause one wheel to spin in the opposite direction when the other is turned while the car is in the air. Honda uses a planetary gearset LSD (it's actually a torque biasing differential, but whatever) which does not respond to the wheel spinning test.

I believe the only way to check for a Honda LSD is to look through the diff housing when the transmission is out of the car. If you can see all the way through you have an open diff, and if you can't then it's an LSD. Or...it might be the other way around, I always get stuff like this mixed up.

 

:chuckles: Or you can always pull a sand test

I think with the LSD, you can't see through, so you're right.

 

Yup, you can never go wrong with the sand test

 

what s sand test

 

One wheel in sand, the other on concrete, make sure there's nothing in front of you, and give it some gas

If you have an LSD, the wheel on the road will grip. If you don't have an LSD, the sand side will spin.
