    I would strongly advise the use of grease and not oil to lubricate the trunnions.

    There were some design changes made in attempts to cure the understeer that the Marinas suffered from.
    Primarily this increased the thread engagement length between trunnion and swivel pin.

    The fundamental reason for failure of the setup is lack of maintenance. If you do not strip clean and grease the trunnions on a regular basis, or as a minimum re-grease them, with an excess of grease, driving the old grease out then problems will occur, whether you use the standard or Walford Trunnions that are intended only to replace the worn or corroded thread on the swivel pin.

    An interesting document describing the changes to both the trunnion and swivel pin can be found here or there

    The reasonable man adapts himself to the world; the unreasonable one persists in trying to adapt the world to himself. Therefore all progress depends on the unreasonable man.

    Loads of Marlin Reference can be found documents here or there.

    I am with Steve on this one - had a one snap for that reason back in the 70s, think the car was only 5 years old.
