When I got my car, the seller said that the it had lsd. I didn't really care about it, but now im curious. How can you tell if you have lsd? w/o disassembling the tranny?

btw, i got a '00 gsr

That is one way. You could just floor it when taking a turn in 1st or 2nd and see if you spin the inside tire. If you don't have lsd that is really easy to do.

yea. take his words.. my theory isn't accurate.

 

jack up the car. spin one of the wheels. if the other side spins with it, it should have an lsd.

or take out the axles and look through the hole. you see a bar blocking it, it's an open diff. if you can see straight through, it's an lsd.

 

u don't have to tear the tranny apart. u will have to take it out of the car, but thats no big deal. if u take it out, look through where the axles go into the tranny. if u can see straight through it, u have an lsd. if there is a pin obstructing your view, then u have an open diff. pretty much LSvtec03 is absolutely correct.

 

contact the seller and ask for a reciept for the LSD

thats the easy way

If it is an oem honda LSD it is helical and spinning one side to determine if there is LSD is not conclusive.

I am positive I don't have an LSD and I will leave 2 strips all day long.

go drive on some ice see if you can get one wheel spinning. or see if you can break one wheel loose around tight corners.

check the tranny code maybe you have an oem LSD equipped tranny. maybe it is aftermarket.

 

I have a YS1 with LSD, and yeah, I've done all the tests. Plus the jacking it up.


So yeah, just listen to what these guys say.

Why can't you do this with the tranny installed? All you have to do is pull and axle and look for the cross pin, if its there, then no LSD.

you can and that is the simplest most conclusive way to check.

 

is there any cons about LSD

 

no

yeah, you have to Buy it,
for most of our transmissions anyways.

 

Check it like you would check an ITR LSD (from the Helm manual):

Operational Check
Set the parking brake and block the rear wheels.
Raise the front of the vehicle, and support it with
safety stands in the proper locations( see section1 ).
With the engine off, shift the transmissionin to 1st gear,
Rotate either front wheel bv hand and check that
the other wheel rotates in the opposite direction.
lf the opposite front wheel does not rotate, or if vou
cannot spin the front wheels at all, the limited slip
differential is faulty and should be roplaced.

Rotating Torque Check
1. Setting parking brake and block the rear wheels.
2. Raise the front of the vehicle, and support it with
safety stands in proper locations( see section1 ).
3. With the engine off, shift the transmission into
Neutral.
4. Measure the rotating torque with a beam-type
torque wrench in the direction shown (top towards the rear of the car), Rotate the
torque wrench more than two complete turns and
take the maximum reading.
5. Shift the transmission into 1st gear and measure
the rotating torque again.
6. Calculate the rotating torque:
Service Limit:
(Measurement from step 5)/(Measurement from step 4) &gt;=2.5

7. Repeat steps 3 through 6 for the other wheel.

 

that is the procedure to check if an lsd is faulty not if you have an lsd.

If you do not have an LSD, it will show as faulty during the rotating torque test. I would expect the ratio of (Measurement from step 5)/(Measurement from step 4) to nearly equal 2.0 for an open differential since the only torque measured would be from frictional drag, not torque biasing.

 

sorry for my noobiness ...but what is LSD?

http://en.wikipedia.org/wiki/L...ntial

 

its a hallucinogenic
a drug which induces hallucinations and alters perceptions
---------------------------------------------------------------------
or its a traction system

A Limited Slip Differential (LSD) is a modified or derived type of differential gear arrangement that reduces wheel spin, especially when cornering at high speed by allowing for some difference in rotational velocity of the output shafts. Limited Slip Differential (LSD) does not allow the difference in speed to increase beyond a preset amount. By limiting the velocity difference between the pair of driven wheels, useful torque can be transmitted as long as there is some friction available on at least one of the wheels.

 

It was a popular drug in the 1960's that could cause ones self to hallucinate. It is also an acronym for Limited Slip Differential. A LSD is beneficial in both acceleration and handling, because it allows both wheels to remain powered even if one of them is not getting traction.

 

ok ive heard many different things but now i want the truth, will an oem itr lsd be compatible in a gsr tranny or do i need to buy a quaife..and im not lookin to spend 900 dollars so i m hopin an itr diff will go into a gsr tranny

 

sell your gsr and buy an itr much less hassle

yes it will work.
