Ford F53 Jounce Bumpers Always Touching: Normal Design for 20K+ GVWR Motorhomes
Finally crawling under my Ford F53 motorhome staring at these front jounce bumpers constantly touching suspension components with no clue if this means something's actually broken. According to Ford Special Service Message SSM 53453 for 2020-2025 F53 Motorhome chassis with a GVWR of 20,500-26,000 lbs, this constant contact is actually normal.
