I just replaced the rear shocks in my 1999 GS400. I've included step by step instructions below.
Remove Rear back trunk wall cover to expose Shock mounting bolts *in other models you have to remove the back seat to get to the shock mount bolts. This is not the case with this GS. I found this out the hard way. That's why the back seat is removed in the pictures.
Unbolt two rear, silver hook-brackets on each side of back trunk floor
Remove 5 plastic fasteners by popping out with screw driver
Pull out the rear back trunk wall cover
Jack up car and remove rear wheels
Remove break calipers
I use a screw driver to compress break pistons a little in order to remove caliper easily
Remove two 17mm bolts on back side of break caliper mount
Suspend caliper or place on stand in order to prevent stress/kink on the break lines
Remove plastic cover on the forward side of the lower control arm
this is necessary to access the nuts to take off the anti-sway bar, strut, and wheel assembly
There are two screws attaching the plastic cover to the lower control arm
Remove bolt that connects the anti-sway bar to lower control arm
This bolt is the one behind the shock mounting bolt
ensure anti-sway bar is free to move in lower control arm
Remove bolt connecting bottom of strut to lower control arm
Remove large bolt connecting wheel assembly to lower control arm
Remove 3 strut mounting bolts in the trunk
Remove shock assembly from car
slip bottom out towards you and then lower and remove from wheel well
Replace strut in shock assembly (or entire assembly)
Mark with scratch the position of top shock assembly with end of spring coil.
Compress spring with spring compression tool until strut is loose in assembly
Remove top nut connecting strut to assembly by holding strut tip with vise grip pliers
Slide out top of shock assembly taking note of position of inner and outer washers and cap
Slide old strut out of assembly
Place new strut in assembly
Replace inner cap, top shock assembly, washer and nut.
Tighten nut by holding strut tip with vise grip pliers
Align mark with top coil end.
Release spring compression slowly making sure mark on top shock assembly is aligned with top coil end
