wait, hold the phone. those upper arms aren't known to go bad, especially both at the same time. what is his reasoning? why did he tell you they are bad?
if they are bad they are simple to fix.
jack up the car, support it on jack stands and remove the wheel.
step 1- loosen the 2 nuts on either side of the strut mount, but don't remove them quite yet. shown below, the circled one is hidden under the plate(16-17mm):

step 2- remove the cotter pin from the castle nut on the control arm ball joint. remove the castle nut(12-13mm). take a ball peen hammer and smack the steering knuckle while pushint up on the control arm until it pops loose. it will then look like the pic below. Be careful that you don't let the assembly flop too far forward, it might pull the axle slightly out of the trans and then you will have fluid everywhere and risk damaging the axle seal

Step 3- remove the 2 upper nuts the rest of the way and use your hammer to tap on the studs lightly until the arm pops down and falls out.
Step 4- reverse the process to install. Torque the 2 upper nuts to 70ftlbs and the castle nut to 14ftlbs. Please double check my torque specs, I just guessed :blush:
it's possible to do both in a half hour to an hour
