Hello All.... I recently purchased an M101A2 trailer. I have been actively working on it, trying to remove the rust, repair/replace the tail lights, etc. While working on rust abatement, I noticed that the chassis is an M116 while the trailer is an M101A2. I have read the TM (found on this site) and have found that all M101 Series trailers utilize the M116 chassis. I also read that all M101A2 and A3 trailers have large U-Bolts in the sides of the trailer, front and rear. These U-Bolts provide lift points for new-style cargo body and are located at each of four lower corners of cargo body. My M101A2 does not have these U-Bolts. Is this disparity common? Additionally, my trailer has a rear stabilizer leg which prevents the trailer from tipping over when loading and unloading cargo. Unfortunately, the stabilizer strut is frozen in place and cannot be extended by threading the lower portion into or out of the strut tube. Basically, it will not unscrew. Does anyone have ideas on how to free the threaded portion of this strut?
