My 75 Delta has just a hint of sag on the right rear. I think this has been discussed before but whats the skill factor for replacing leaf springs.Do you do all of them , both sides etc. Car has 95000mi. The ride is ok and I don't see any frame rot. It just looks bad from HER BEHIND.

 

Rear springs on these cars are very easy to replace. I don't think you can buy just a single spring - to quote Woody Allen, "they usually travel in pairs".

Jack the car and support it under the frame. Use your floor jack under the rear axle center section to raise it up. Disconnect the bottoms of the shocks. Lower the floor jack until the springs fall out. You'll need to hold the new springs in place while a helper raises the jack. Connect the shocks, and you're done. Be sure to take note of any rubber isolators. Also, there may be a preferred orientation of the spring ends on the pads. The Chassis Service Manual spells this out.

 

Thanks Joe.
