Is there a link to how to change the diff fluid on a 94 sc400??? any help would be great!!!

 

if its like a 92 sc300 you just take the drain bolt off the pass. side of the diff and let it drain(jack the car up higher on the driver side to drain the fluid better.)

and then pump the new fluid in until its full.
BOOM your done.

 

when he means pump till its full he actually means till it starts constantly flowing out of the fill port. anymore that that can actually be bad on the diff.

 

search user "Blizzy," youll find everything you need for diff. info

 

This is for the LS400, but it is the same procedure.
