Larry,
This MIGHT work for you. It somehow worked for me.
Put your car on jack stands, remove both rear wheels.
Put a sissor jack under the trailing arm just below the
shock link attachment. Push the T/A upward a little
with the sissor jack, 1/2". Remove the shock link assembly.
Now lower the sissor jack slowly and the coil spring
will push the T/A downward. The axle will move downward
and the U-joint will permit the middle to rotate upward
as well. The axle will bump the frame on it's way downward
and then seperate enough for you to slide the gaiter in place.
If that doesn't work, take a time out cruise. I hope this
helps a bit. If not, the experts will have better methods.
