How Tight Should a Castle Nut Be On Boat Trailer Spindle
Updated 06/03/2021 | Published 06/02/2021
Question:
Had to replace a damaged spindle on my boat trailer. It is a 4 wheel trailer with surge brakes . boat is 23.5 foot trophy. Should the castle nut on the inside of the spindle which attaches the spindle to the trailer be a specific torque? Had to use a 38 mm impact socket and breaker bar to remove the damaged one. Any advice would be much appreciated. Ty

Expert Reply:
There isn't a torque spec for a spindle castle nut like part # 165931. The castle nut will need to be tightened until there is no side to side play with the hub and then backed off a quarter of a turn or until the cotter pin or retainer clip lines up. There is not a specific value for this.
