Can the rear bump stops be changed without removing the rear struts on this car or is there access to the bump stops without removing the struts? Thanks

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

No it is separate from the strut. It is by the two bottom bolts of the strut. It is a rubber insert in the shape of a eight. Had someone install new struts and they left them out due to not being able to line up bottom strut bolts. Car rides fine but felt they were there for a reason. I have not looked yet but wondered if there was access to put them in without removing the bottom of the strut. Thanks for responding.

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.

That is what I thought was going to be the answer. I need to look at it and hopefully there will be a couple of bolts holding the rubber bump stop in. The rubber bump stop is actually on the leaf spring and not the strut, it just came out when the strut was removed. They were suppose to have ran a bolt down the center of the rubber insert to keep it from coming out which they did not. The bolt comes with the new struts. I was told that as long as I don't put a lot of weight in the car and bottom it out it should be okay. I do not have the tools needed to remove the strut myself so I might just let it go for now. I definitely do not want to take it back to where I had it done. Thanks

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.

My rear struts do not have coil springs on them. I have put a photo of what I am talking about. It is located by the bottom of the strut.

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

I have a 1991 Chevrolet Lumina Euro and it only has a strut with no coil spring and the rubber 8 shaped insert that is separate from the strut itself. It is located at the side of the bottom of the strut. I have never seen anything like it. Strut and strut mount is fine. I just wondered how to get the rubber 8 insert as in photo back in or is it really going to be a problem if I do not? Thanks for all your assistance.

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.

Thanks for that information, it was very helpful. So basically those rubber inserts are just for ride height? If you ever remember how you got them back in I would really like to know how you did it. I should have just taken the car to someone who knew what they were doing. Thanks again

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.

Definitely not a job for a do it yourselfer like myself then. Unfortunely it will have to remain the way it is for now. Hopefully I won't break anything. Thanks again, you answered my question.
