Top front wishbones

[TVRleigh_BBWR]

I can't find my bible, plus don't have a cortina manual,

So does anyone know how tight you do the bolt on the top wishbones, I know they have a castle nut and split pin so assume they are not done up too tight.

I've fitted polly bushes on them, but they was quite expensive.

The bible says the following
replacing the top wishbone
The process is the reverse of removing the wishbone
The ball joint nut should be tightened to 30-40 lb /ft and then tightned a bit more to align the split pin hole and the slot in the castellated nut. Refit a new split pin. Do not exceed 60 lb/ft torque when doing this


But not sure if that helps ?

Cheers

Thanks Paul,

But I've got nylock's on the ball joints, was looking for the instructions for the wishbone to the chassis.

My book of words says 'Upper arm pivot bolt 52 - 70 lbf.ft'. Lower arm is 52 - 59 lbf.ft.

Thank you, seems a bit tighter than I would have thought. on the lower I have rose joints so that will be different.

Don't forget the arm is not supposed to pivot around the bushes, nor the bushes around the bolt... the bush compliance is supposedly included in the springing and damping 'calculations' whereby the bush distorts under load and regains its ahape once released. Supposedly
