Pull 'em both apart and clean 'em both out. Compare spring tension and travel with each other. If they're noticeably different you may want to replace.

Per my posting in the parts repository:

Superwinch manual hubs
D50
Montero/Pajero 83-90 (doesn't specify engine or trans)
MFR P/N 400543

Between $110 and $130 depending on where you go. Very quick and easy to install. Also more reliable to stay locked when you want them locked [Linked Image] and unlocked when you want them unlocked [Linked Image].
