Help me solve a mystery. I have an annoying rear rattle/clunk from the left (driver) rear that seems like it got worse after I had a rear tire, but that might have been a coincidence.
I saw this as an excuse to do some rear suspension work, and I have replaced the rear shackle bushings, two broken leaves, and rear shocks. It maybe got marginally better with the shackle bushings. I get it both when I am engaging the clutch and if it is just coasting, so its not clutch chatter, but I am wondering if it is driveline related.

Let me know of what ideas. It is annoying more than anything.

Maybe a u-joint.

When our 49 Deluxe made such noises…Master Mechanic, Alex Alfaro finally determined it was the rubber seal around the trunk lid of all things! We replaced the seal…No more noise. Ernie in Arizona

I had a rattle/clunk sound coming from the same area and I looked and looked and could never find it. I happened to find the source by chance one day while working on something completely unrelated.

I don't know if you have a track bar like my '53 Cavalier, but one of the mounting bolts broke on the bracket that mounts to the spring. The bracket would jump up and down when I hit a bump, particularly noticeable going over train tracks.
