transverse spring isolator pads

I have a 1993 Regal Custom. The friction pads on the transverse spring had worn off. I replaced with the aftermarket isolator pads. These work well. The problem I am having is that after a few months they tend to shoot out. You will hear a large bang and then see the pad shoot out in the rear view mirror. This seems to happen when their is a load in the rear of the car. Has anyone else had this happen and what can be done to prevent this.

I'm thinking that you're not installing them correctly. When installed correctly they can't come out unless you raise the spring off of the pad. Make sure the flat side is facing up against the spring.

I installed them with flat side up. The pad straddles the pocket area of the spindle. Once I was able to retrieve an ejected pad. The lip on one side was broken off. Sometime they will last for quite a while ( 6 months or more) Other time they will eject after just a month of use. Can weak shocks in the rear affect their performance.

I know what you are talking about....but never had to replace the pads on the end of the spring....did they have to be glued on?

They are not glued to the spring or attached in any way. They are an aftermarket solution to when the original pads have worn off. They are plastic blocks the sit in the spindle and the spring rests on top of them. They work well. I'm just having a problem with them staying in place.
