First of all, I don’t know much about cars so I apologize for any ignorance!
Anyway, so a little over a year ago I had to have my head gasket replaced and when I picked it up they told me I had a cracked motor mount. After having just spent an exorbitant amount and being poor, I decided to wait to fix that. It seemed to run fine so I didn’t worry about it too much. Sometime last year I started hearing this rattling noise when I pushed the gas. It would start and then die off. But it didn’t do it all the time.
Fast forward to the past month or so and I’ve started to get vibration and shaking, usually between 60-70 mph. Thinking it was my tires, I took it in to have them balanced. It rode smooth after that for a few days and came back. The rattling noise has also become more prominent and is pretty constant now. I took it back to the shop and they told me it was more than likely the motor mount. So I went ahead and had that fixed today.
When I picked it up it seemed fine. The noise seemed gone and it rode smooth. But as I drove home and got on the interstate everything came back and sounds/feels just as bad as before. What gives???
