Squeaking noise during acceleration

Is it true that I need to lift the car up and take off both wheels to get to the plugs? I only have the jack that came with the car.

(I don't believe the dealership for 1 second)

It's easier with the wheels off, with only the stock jack it's unsafe to slide under even with the wheels on. If you can barrow some jack stands you can do one side at a time, might as well replace them. You will need a metric allen set for the coil packs, long extension and flex coupling for the plug socket. Best to have a torque wrench for the plugs (don't know the factory spec) but in a pinch you can just make sure they are a bit tighter than snug, I also suggest using Bosch plugs.

Here's a video that actually works.
