Hi, Well seeing ive just done mine and it all went well id'e post up how i did it.
Firstly i parked on a reasonably level driveway,Chocked rear wheels and in gear with handbrake on.
I got under and set up jack stands roughly to the height it was sitting at, One under the diff housing,between radius arm and swivel housing, ( Oh one side at a time)
Then another stand under the chassis behind where back off radius arm meets chassis.
Jacked the whole front up, took off wheel and placed stands and lowered onto them.
Next i undone the rear nut of the radius arm where it meets the chassis. removed the rear mushroom bush.
Then with rattle gun loosened the bolts holding radius arm to diff. ( these are Tight,Had to grind one off)
Next you have to remove Tie Rod joint on the side your working on and swing out of the way.
Punch out bolts with brass punch while supporting radius arm, slide out towards the front of the car.
Pressed out old bushes and replaced with new rubber ones.
To install , put new mushroom bush on the back off arm and slide in, put rear mushroom bush on, washer and tighten,you have to tighten the rear nut to squash the new bushes so the front bushes line up, Put new bolts and nuts through front bushes ( $30 set from nissan ) had to jack up a little to line them up,
Done them up (not tight) Put wheel back on removed stands and jumped up and down on the front end.
Undone all the nuts enough to put locktite on thread and torqued them all up with car sitting on wheels (important) if you torque them up while jacked up you will tear the bushes when the cars sitting where it should. This apply's to any suspension bush!!!
Hope this helps, found it an easy job.
