Mystery Clunk When Backing Up Solved!

[Fifty150hs]

Awhile back I posted about having a weird clunk when backing up. I can find the post, but I thought I'd post that I accidentally fixed/figured out the cause. Last month I pulled my brake pads and scraped off the "glue" type anti squeal and replaced it with anti squeal grease. I did it because I had developed a squeal during low speed braking like in stop and go traffic. Very annoying. I had intended to replace it with new "glue" but my bottle was all dried out and the auto supply store didn't have any. So I went with the grease.

The grease worked and no more clunk when backing up! So, maybe the "glue" isn't the best way to go for anti squeal. I don't know, but seems to work and it eliminated another problem.
