Rear Suspension Rebound Snubbers

Post by brokencase » Thu Feb 08, 2018 7:33 pm

I'm looking for a good picture of the original rebound snubbers for the Scorpio. They are inside the rear springs.
I was going to try to 3d print them in 90 duro polyurethane. But I need a good picture to model them in CAD.
If someone has one laying around and could maybe take some dimensions off of it that would be great.

Rebound model is made. It will take 16 hours to print one.
I'll take some pics once I get them mounted in the car

What do your current ones look like?

I just took these pics of mine ((150K miles). How/why would yours need to be replaced?

Ed, your pictures show that your rebounds are gone. They probably totally disintegrated.
What your pictures show are the metal pedestals that the rebounds mount to. The rebounds pop onto the "stud" in the center.

I've printed out the new ones, I just did not have opportunity to mount them this weekend because I was without power due to the storm.

Aha; I get it. Thanks for the enlightenment.

The apparent similarity of the cone shape in your Thingiverse rendering and the snubber supports suggested that was what you were printing.

So, I'm a buyer of a set if your prototypes work as intended.

Just an FYI, the ones I printed are actually a little smaller that the originals (diameter wise). I did this in the hope that I can squeeze them through the coil spring too ease installation. Nonetheless, I believe they are slightly more firm than the originals to make up for this difference (but they not 100% solid). This is the plan anyway, but we will see how it goes. One minor concern I have is if I will be able to snap it over the "stud". I have a 16mm hole that I measured off of the original, but the new polyurethane rebounds don't stretch as easily as the original foam units in this area. I might have to do a razor "cross cut" to allow it go over the stud.
