Rear bump stops

The stops on the strut shaft themselves between the top strut mount and strut?

I have never ran across those type of struts, but sounds like you could just unbolt the bottom of the strut and put them back in.

You do not have leaf springs in the rear. I posted a picture of your rear strut see the part of it? That is your bump stop, you would have to disassemble the strut to replace that.

You have a 1991 Chevrolet Lumina with rear leaf springs? I looked up the strut assembly and that is the one it shows.

Hi guys. I have worked on a few of this style, and you are right, it is a single leaf that goes from under the left strut to under the right strut. It is a real pain to get those cushions back in. That is why you are supposed to bolt them in place to hold them there while the strut is removed. I am sorry that I don't remember how I did it, but I did get them back in. That was a long time ago.

You are going to find that without them in place, the rear ride height will not be correct. As a suspension and alignment specialist, I get very picky about ride height, (and I refuse to work on any lowered car or raised truck). That is for liability reasons. Altered ride height changes braking front-to-rear balance, steering response, handling, as well as comfort. If you are involved in a crash caused by the other guy running the red light, his lawyer or insurance investigator will shift part of the blame onto you because you were less able to avoid the crash, and they will be right. These are the types of things we have to keep in mind every time we work on a car. Your mechanic opened himself up to being party to a lawsuit, and you could become involved as well because you are knowingly driving a car with an altered suspension. You can always play "stupid", but someone will follow up on the missing parts. If the mechanic says, "the customer said it was okay", it is all over but the sniveling.

The dealership I worked for was the county's impound yard for all cars involved in fatal crashes. The cars were locked up so no one could tamper with them until the lawyers got done inspecting them. You would not believe the things they find to shift the blame from their clients.

I DO remember I had the cars on a regular frame-contact hoist that let the wheels hang down freely, so there wouldn't have been as much pressure on the spring as normal;... And I know there was more than just me working on it. I seem to recall using a really long pry bar. The cars would have been a few years older than yours, but it's the same suspension system.
