I went to a tire shop and they told me it is possible the motor mounts need to be replaced.

Here is the scenario. I am driving at 20mph in 2nd gear and accelerate to about 30mph and shift into 3rd. When I shift into third I let go of the steering wheel and the car tracks straight but as soon as I shift into 3rd the car starts to pull to the left.

Anybody with any input? My mileage is at 33K miles and it is a MY00. Car is lowered on Swift Springs and I'm running 18" wheels and I have not done an alignment yet.

Another problem I have is when I just installed the 18" wheels without the lowering springs, the car use to vibrate and you feel it in the driver seat at 75-80MPH but the steering wheel has no vibration.

If anyone has a clue please chime in.

Thanks.

 

 

and check tire diameter or you can swap rear wheels from left to right and see if it pulls the other direction. dont worry about the rotational direction because that is only for treading water

 

Sounds like you have lots of problems.

1) Car pulls under accelleration. If it just started doing this with no other changes to the car, then it's most likely a tire pressure issue. Check your pressures (likely a low left-rear tire). If this started when you put the springs on... get an alignment.

2) Vibration from the rear. It started when you put the 18s on, so I suspect one of the rear wheels wasn't balanced properly. Take it back & have it re-balanced. If it started at the same time that the pull started, you probably hit a pothole/curb and damaged the tire (and possibly wheel). I'd get the whole thing checked out.

Good luck.

 

Also, you need to get the car aligned ASAP.

 

Huh?

Check the tire pressure.
