Top strut mount (3 nuts): 58 N.m (43 ft.lbf)
Top strut lock nut: 28 N.m (20 ft.lbf)
Bottom nut: 157 N.m (116 ft.lbf)

Rear Struts:
Top strut mount (3 nuts): 64 N.m (47 ft.lbf)
Top strut lock nut: 27 N.m (20 ft.lbf)

I have the shop repair manual for 2004 LS430 , so please let me know if you need other specs for this model year.

Yes.

Go to sewell lexus parts and you can see diagrams and parts/parts numbers for all this.

It doesnt really show a front bump stop.. but ive figured it out..

now on the rear the cap above the strut mount, curious on why its got a different torque spec.. It appears to be a large washer between the chassis and strut mount..

Here's a picture showing the strut lock nut that holds down the large washer (torque to 20 ft-lbf), the 3 strut top mount bolts that hold the strut/spring assembly to the car (torque to 47 ft-lbf), and the strut mount cap with rubber seal (torque to 18 ft-lbf).
