Vibration turning left, not right

[pilot4fn]

Good candidate is also engine mount. If (when) that is done, ethe engine-transmisson setup moves fairly well in the car..

So here is another update:
- changed our transmission mounts
- changed engine mount
- changed the front ball joints and supports
- full alignment completed

Realized that maybe the vibration was actually coming from the back.
- changed out both left and right axels (CV)

The sound seems to be a bit less but unchanged.


So now I’m going to start looking at the power steering pump.
…


The craziest thing is that there is no vibration if I turn off the car and glide at any speed and go straight or steer.


So the vibration is for sure from the engine in some way.

I now think it is either the power steering pump or steering but no way to easily verify….

Do I just replace it to find out?!

The "craziest" thing is that you just keep throwing money at it... in an effort to "find out".

Or, in the wise alternative, you could pay a pro to diagnose it. With all the parts you've thrown on it I suspect it wouldn't take long for a pro to arrive at a diagnosis.

You do have a car set up for the next 50,000 miles, though.

Good luck?

I agree I could hire a pro, but what is the fun in that? I dove into this car head first to learn. And I often learn more from my failure than my success.

I’m here on the forums for mentorship and education. I’m hopeful for some suggestions on root causing this vibration.

And setting up the car for the next 50k mi is absolutely the secondary goal.

When I picked up my 98 I was all over it... replace this/that looking for a fix. That car has instilled in me a greateer sense of patience and, now, when something goes wrong... I'm trying to avoid throwing money at it instead trying to diagnose then fix.

I'm really interested in what is causing your vibration and when next you throw a part on it that stops the vibration I hope you report. Good luck.
