I had a slide bolt freeze up on my driver side rear a few months ago I ended up removing the caliper and using a regular old propane torch to heat the sucker up and I was able to free it.
Hi forgive me for never introducing myself... But I believe I know what that noise is and unfortunately what will happen if left unattended... Last January I purchased my very first LC and after about two months I noticed a sound very similar to that in the YouTube video... One morning on my way...
