Just to reiterate, I'm not overly concerned about it. Reproduction is possible. Even though they charge more, there are many top-notch custom fabricators out there who can make parts that are superior to OEM options. At some point, though, I suppose, it becomes pay to play with any automobile ...

So, I was hoping to find a facility that could fix this by Friday, so I'm planned to say 1) on a road trip when I call tomorrow morning. 2) I am experiencing vibrations in the drive line at speeds of 75 mph and beyond; these vibrations become worse as the speed increases. 3) I am very suspicious ...

Tomorrow morning, I will phone each of the stores on my list in San Francisco to see if they can get it fixed this week.

I know there's more to diagnostics than just looking at the motor mounts and flex disks, but they seemed fine.

Oh, I see another piece of information that could be helpful. The vibration frequency somewhat fluctuates as the acceleration reaches 80 mph or higher.

Just so you know, Claude said that I probably shouldn't travel faster than 75 mph, especially when driving across the desert in extreme heat, just in case it's a flex desk. Seems like wise counsel. The additional MPG is also something I will not dispute.

At the next stop, I shall give that a go. Going uphill or downhill doesn't change the sensation. It doesn't appear to be as bad going downhill. My guess is that it's because I'm reducing my throttle input when descending.

To compare the old and new feelings, "planted" probably isn't the right word ...

At 75 mph, I'm experiencing high-frequency vibrations within the cabin. Before I had the tires rebalanced, I thought it was the new/used tires I had purchased, but now I'm not so sure.


I can completely eliminate the vibration by briefly releasing the thin pedal. Going 75 mph is bearable, but after ...

I am grateful.

Sure, I'll give it a go. How would one go about connecting the ground wire to the head unit?

As far as Bluetooth, USB, and CDs are concerned, it does it all.
