boodog1937 Report post Posted June 20 I have one Jack right front that leaks down under load about quarter inch every twelve hours, it will continue to drop four or more inches off level. No signs of fluid leakage anywhere? Any advise on how to test or what might be causing the issue would be appreciated. 2013 Thor Tuscany 40 foot diesel pusher. Am wondering if that one Jack has an internal leak. If so can it be rebuilt and where? Share this post Link to post Share on other sites
wildebill308 Report post Posted June 21 I would clean and lube the shaft and run it 5-6 times. If that doesn't help I would call Lippert. Bill Share this post Link to post Share on other sites
