Vibrating at 50 MPH

Hi,

Can you drive through the vibration? For example, it starts at 50 MPH and by 60 MPH it stops?

Have you checked tire balance or for a bent rim? Are there any clunks or clicking when you place the vehicle in gear or make a turn?

Let me know. Also, let me know if you feel the vibration more in the floor/seat or in the steering.

Take care,

Joe

Hi Joe, yes, you fill vibration through the pedals, seats and the floor (front) and a little in the steering. Just had new tires so the balance is fine. stops around 70MPH. Gears go through each one as normal, no noises at all.

If the vibration is more noticeable via the floor and seat, it likely is coming from the rear of the vehicle. I would start with the basics. See if there is a rear tire balance issue and inspect the rims. I realize the tires are new, but there could be one out of balance or a bend in the rim.

If they are good, inspect the new tires to see if there is any uneven wear starting such as cupping. The rear of this vehicle is alignable. An alignment may be the cause. However, when you can drive through the vibration, it is usually a tire or wheel.

Let me know.

I have been told it could be something to do with the catalytic converter. The engine vibrates when parked.

That sounds like a misfire. If it is running rough at idle, there could be a few things causing it. For example, an engine vacuum leak, fuel pressure issues, compression issues, and certainly, a plugged catalytic converter can cause issues.

Is the check engine light staying on when the engine is running?

Let me know.

No, the engine management light is on. I need a new engine mount but do you think that would cause so much vibration?

Hi,

If the light is on, have you checked for diagnostic trouble codes? Here is a link showing how it's done.

If you don't have access to a scan tool, most parts stores will test it free of charge.

As far as the engine mount is concerned, yes, it could be causing the issue. Which mount is bad? Is it loose, broken, or what is actually wrong with it?

However, if the check engine light is on, it could be a misfire.

Let me know.

Joe

Hi, no engine management light is on, it's the top right engine mount.

Chris,

The mount could be an issue. What I suggest is to replace it if it's bad and see if that was the cause. Since it needs to be replaced, it won't be a waste of money.

I have a question. Are you in the US because I'm not showing the MK2 1.6L as an option?

Let me know.

Joe

Hi Joe, no, not in US, I am in the UK.

Hi,

That makes sense. I went through two manuals trying to find it, but I had no luck. Regardless, a mount can certainly cause it. The interesting thing is you can drive through the vibration which usually indicates a balance issue or bent rim.

Let me know if the mount takes care of it.

Take care,

Joe
