Rough Vibrating

[yousefi99]

I have an 85 318i. In the last two weeks, I have noticed a rough vibration progressively getting worse. I can feel it as I drive. It does not start until around when I get into third gear, and then continues at all speeds above this. The car runs fine, but I have this bad vibration. I have checked spark plugs and all related parts. All is fine. Is this my transmission or clutch? Any ideas? Help me keep my baby running smoothly.

Thanks

Could be a wheel alignment and balancing issue.

If it only starts after a certain speed it's a very big possibility. My car does this.

I just had new tires put on and balanced. I feel like the noise is coming from the engine or transmission area. Thank you.

Wheel bearings?

When I take my foot off of the gas, the vibration stops.
