I recently replaced the lower passenger left contol arm on my 1994 850 wagon. I'd say it was relatively easy, a couple of hours or so. I used a Haynes manual as my guide, along with some common sense.Double check things to be sure nothing changed bwtween 94 and 96. Besides typical soctket and combination wrenches, You will need a set of metric hex wrenches that will fit on a socket wrench and also a torque wrench to set the bolts to the correct torque spec. the haynes manual lists all those #. The dealer wanted way too many $$$$ for the part so I purchased from autohuasz.com in arizona, very inexpensive and it was identical. remember not to use the old bolts over again, new ones come with the new control arm and don't skip the final torque with a torque wrench. good luck
