My 2007 Ford Focus ZX3 SES (65k miles ) has a vibration at all engine speeds. Other research has led to a high probability that this is from worn out motor mounts.
I have read after market replacements will typically wear out again in a few months and that I should get them from Ford. True?
I have also read that all three should be changed at the same time, or the others will go bad very quickly after one is changed. True?
I've watched some videos about changing them, and it looks to be pretty straight forward. However, they all use an impact wrench in the videos. Do I need one, or could this be done with regular hand tools? Do I need a torque wrench also?
