Right Front Shock Replacement

[73FJ40]

@NellieFJ40

Thanks SO much!

You might be able to help me out one more time also. Do you know the torque values on the castle nuts and large top nut? I've looked at the FAQ but am not sure what's what.

If the "large top nut" is the nut that holds the upper shock pin in place for the front shock towers, I would replace the lock washers (94512-01600) and just tighten it snug with a 1/2 drive ratchet handle.

Regarding the castle nuts, you don't torque them; my understanding (others, please chime in!) is that the concept is to tighten them up to slightly compress the rubber bushings, align a castle slot with the cotter pin hole, and pin the nut in place.

And thank you once again! I now have all the info I need to finish up my suspension install...I think!

Update on the large lock washers for the shock tower pins: 90204-16001 is the new number, superceding the 94512-01600 number.

If your shock tower looks like this, and if your 1980 is the same as my 1973, the nut thread is M12x1.25. (fixed a typo; had been M14

I have a castle nut because my shock stud is drilled for a cotter pin.

Anyone know the size and pitch of the big nut on the right?

Anyone know the size and pitch of the big nut on the right?

The part number signifies 16mm, I don't remember the thread pitch offhand.

In any event, the nut appears to be available from Toyota, part no. 94115-41600, for $1.64 list price. The lock washer is 90204-16001, about $2.10 list.

I pulled the shock pin and took it to the hardware store to find a nut. It's 16mm x 1.5.
