Hello all i'm trying to find out what differential is in my 99 au falcon. If anyone could help it would be much appreciated.


Regards Brad.

what do you mean? IRS? Solid. single wheeler? LSD? what ratio?

Would like to know if it has a LSDor not the gear ratio i can figure out.

if its a forte or futura= no lsd fairmont=no lsd , xr6 solid axle= optional lsd. and not sure about ghia or xr6 with irs..

otherwise you can find out if it is lsd by jacking the rear of the car up with both wheels of the ground, turn the drivers wheel and if the passenger side wheel turns the same way its a lsd, if the passenger wheel turn the oposite way its not lsd...
