Lexus has two distinguished front springs for my '96 Sc400: left and right. On the spring there is a blue marking for one and white on the other.

Can anyone tell me which is the left spring? Thanks,

 

right is the one with the white marking...
but actually i dont' think it matter much, just make sure the spring is aligned..
marty i think eveyone knows that the right side depends on where you are facing...

 

The reason I'm concern is with the rear springs the marking is similar thus they're interchangable.
However the front springs have different marking and they have different part number thus that was why I believe they're not interchangeable.

 

Can't remember off the top of my head however the marks should be on your factory ones if you are going to replace them. Always judge the right and left side by sitting in the drivers seat. Driver Side=Left side and Passenger side-Right side.
