diff shudders

anyone interested , the shuddering while turning tight lock at low speeds
in our diff was remedied by changing the oil to mazda spec limited slip
diff oil. the oil removed was clean and looked good but the properties are
crucial

the oil came from a mazda dealer,(its mazda branded oil) its made for lsd's
, its expensive but very viscous and it does the trick
a 2 liter pack but you only need 1 liter

Shuddering LSD's that get fixed with either LSD specific oil, or LSD
specific additive in normal gear oil, are only for clutch-type LSD's.

Early MX-5's had Viscous LSD's and later ones have TORSEN LSD's from the
factory. Neither of these types require, or respond to, LSD specific gear
oil... normal gear oil is fine. Neither factory LSD works on friction, and
thus, friction modifiers will have little if any effect...

The only MX-5's that will behave differently with LSD oil are ones that have
had a clutch type diff installed... the most common being a Mazdaspeed
item, or one from an RX-7...

local mazda dealer

Hi,

I actually went to Mazda today to find out about this. Its called something like "Mazda Slip Resistant LSD diff lube". Their parts system lists it as for "all rear end differentials".

My torsen has a whine under light throttle, so I am keen to try anything before having it pulled apart at great expense. Cost me under $30 for 2l.

I will report.
