Lsd ?

[Mr2dude]

Hi,

How can I tell if my car has an LSD in it ? I need to order replacement driveshaft, but guy on phone says only way to tell is be removing existing driveshaft an looking inside gearbox for a "little hole, big hole or diagonal bar going across".

Is there easier way to tell without taking anything off. It means car will be stripped down a few days while i wait for parts, instead of getting whole job done in a day.

Cheers

Steve

p.s. Its a turbo engine btw

jack the car up, put it in first, and spin one of the wheels..

If you both wheels spin the same way - You have an LSD.

or if you dont have a jack to do that....

find a piece of private land, (gravel would be good), in 1st gear, drive in a circle at full lock, then floor the accelerator

If the inside wheel just spins, and the outside one remains at normal speed, you dont have a LSD

if you have one, then (apart from the car spinning around) the wheels will turn at similar rates..

[Mr2dude]

Just jacked it up...

Turn one wheel forwards, other wheel goes backwards.

But guys at fensport says, this is not proper test, because if i have a "bias-bar" ? (Is this the right word, mabey he said "balance-bar" ?) then it would happen with an LSD fitted also.

Does that make sense ?

Sorry it's not got a LSD fella.

It doesnt matter if it's a Tubo engine, It was only an option for a Rev 1 and 2.

But came as standard from Rev 3 upwards

Fidgits option is the more fun way of testing though. :P

Limited Slip Differential (LSD)

For models produced intended for the US, from the model revision in late 1992 onwards a limited slip differential was standard for all Turbos - previously in the 90-92 model years it was an option. It is not known if a LSD was also standard for Japanese Turbos from '92 onwards, although its appears to also be the case.

To verify if your car has a LSD, check the vehicle identification plate on the inside of front bonnet. There are a number of codes given there, including the transmission type, whose code starts with the sequence "A/TM"

For example,    A/TM:-    735/E153

If the last digit before the /E153 is a '3' or a '5' then the car has a LSD - therefore in the example above it does.

The second part of the code is the transmission type- E153 is a heavy duty manual transmission for the Turbo.

The car is not a complete car. The engine is sitting in UK 1992 T-Bar, so VIN wont help here much. Thanks for the post though.

Round & round we go......time to make "checking if I have an LSD" a sticky I think. A search would have found the answer. The stock LSD on the mr2 is a viscous type lsd. If you turn one wheel, it will act like an open diff so that WON'T WORK. The stock LSD is NOT a positraction or locked differential.
