Rx 300 Rear Axle Lsd

kybucks · February 11, 2003

I just bought a 1999 RX 300 and love it so far (I have only had it for two weeks). How can I tell if it has a limited slip differential in the rear axle? If it has the rear LSD is there any special oil additive that is required? What about the center LSD? Does it require a special oil additive.

Any tips or web sites containing maintenance information would be appreciated. I am planning on changing all fluids.

Park one rear wheel on the grass, drive off and put the foot down!!

If you leave a deep skid in the grass, you ain't got an LSD.... :(

Thanks, I could try that but I might tear up the yard. Can I tell by just looking at it or is there a special tag or number on it?

Hi;

According to www.japanvehicles.com/newcars/toyota/HarrierMC/main.htm you can't have the rear "Torsion" differential with VSC fitted.

However, both are extra-cost options, so you may have one, ot the other, or even neither! ...but not both...

I'm waiting for a manual, so I can't help with VSC yet, but if you can determine whether it's fitted to your car, then you can be sure you won't have a "rear Torsion LSD".

I hope this helps.

Thanks,

I don't think VSC was available on the 1999 and 2000 models and I don't think that the limited slip rear diff was available after 2000. I am going to try calling Lexus to see if they might know by the VIN number.
