Hi Daren

I break the LS400s and have a couple of good low miles used ones if your interested

To remove the old ones , remove the front strut [ shock + spring ] then undo the sway bar link bracket that is attached to the straight lower arm that goes from bottom ball joint to ally sub frame.

then undo the 2 x 19mm nuts that attach the lower strut bar to the straight lower arm , then undo the 22mm Nut at the Bush end of the strut bar , and remove its camber adjust bolt.

Refit is a reverse of the above.

Torques are : Strut Bar - Camber bolt / Nut 181Nm + the 2 x 19mm nuts 164Nm

Sway Bar Bracket small Bolt 59Nm + Nut / Bolt 113Nm

Shock Absorber Lower Nut / Bolt 157Nm + Top 3 x 14mm Nuts 58Nm

You may want to undo the Top control arm for access and you should support the bottom of the wheel hub as the whole assembly is heavy and will but strain on the straight lower arm bush

Good Luck

Hi Daren

Just remembered , mark the position of the camber adjust bolt with tippex , so it is in the same position after refitting

The independant double wishbone suspension fitted to the front of the LS400 is virtually the same set up from series 1 to series 4.The information regarding torque for fastenings is relevant but is supplied by the second post.
