Hello and thank you for using JustAnswer.com

Front or rear? Which one the 17mm or the 19mm? Also let me know how many miles are on the car?

Let me know, thanks Jay!
Customer: replied 6 years ago.
i have only tried the front so far, 17mm and the car has 42K miles on it
Expert:  Jay replied 6 years ago.
How big of a ratchet are you using? I see you said you tried a impact wrench, do you mean impact gun?

Let me know, thanks Jay!
Customer: replied 6 years ago.
yeah impact gun, ratchet is about 10 inches long
Expert:  Jay replied 6 years ago.
1/2 impact gun? You have air? What is the air pressure?

Let me know, thanks Jay!
Customer: replied 6 years ago.
3/8 with air, pressure is at about 180 psi
Expert:  Jay replied 6 years ago.
you need a 1/2 inch gun. The 3/8's won't budge them. I would use a long ratchet and see if you can crack them free, then use the 3/8 gun. Other wise you need a 1/2 gun or a long ratchet to crack those bolts loose.

If you have any more questions on this, please feel free to ask. Thanks Jay!

what makes the 1/2 better than the 3/8? how long of a ratchet
Expert:  Jay replied 6 years ago.
More torque and a stronger socket. The 3/8 doesn't have as much torque and the socket side walls are thinner so the metal stretches a little and makes it harder to crack the bigger bolts loose.

You want to have a longer ratchet to give you good leverage on the bolt to crack it loose. Around 12 inches or so

Thanks Jay!
