  • Rear axle nuts - nylock only, no cotter pin - is this safe?

    I guess the title says it all, I am putting my car back together after the key way pin saga (If you have been following it) and I notice that the nut holding the rear hubs on is a simply nylock nut! On all my previous English cars it has been a Castle nut with a cotter pin.

    Thoughts on this please? Seems rather unsafe....
    Thanks, Pat

    Are they both right hand thread or is one right and one left?

      They are differently handed and naturally torqued. The initial torque of 200 lb/ft (if memory servers) is quite a bit. I've never heard of any coming loose.

      *edit: The above is for DeDion setups. Don't know about live axles.

        My Lotus owner's manual shows 110 ft-lb for the axle nuts on the very similar Standard 10 axle.

 - page 116: Hub nuts 200 lbft / 271 nm.

          As Ron pointed out, it probably differs between model years. The guide is for a 2002 car.
