The Holland Group has two publications to answer the question of whether to rebuild or replace a fifthwheel.
Holland has developed a service bulletin, #XL-SB058-01. By using this checklist, a decision to replace or rebuild can be made. The second publication, Fork in the Road, addresses the economics of this rebuild-vs-replace decision. For more information, contact Holland, 467 Ottawa Ave, PO Box 2099, Holland MI 49422-2099.
