Trying to charge me $160! blah!

[Twin]

So my local mechanics are trying to charge me 160 to remove and replace my 16 wheels studs. The dude says theyre gonna have to remove the spindles on the front wheels because they will get in the way and theyre going to have to replace the bearing as well. Replacing studs i can do myself but i dont have the time nor an impact gun. I dont know if doing it without an impact is safe. Also, im not too sure about the spindle and bearing deal. I think theyre just trying to jack up the price. What say you fellas?
