    The "getting worse when you accelerate and better when you let off" points to u-joints.

    Do you hear a "clunk" when you put it in gear or a "ping"

    Also, get under neath your vehicle, see if you can "spin" the drive shaft even just a tiny bit w/ it in park. If it moves at all, replace the joints.

    Replacing a transmission mount couldn't hurt, especially if you don't know the last time it was changed. They are easy to change and cheap.

    I have a vibration in steering wheel around 50 mph that I believe is wheel balance. My concern is the low rumble and vibration I get when I coast. Under power it's not bad. Let off the gas and I get a low tone harmonic and a deep vibration. Thoughts??

    you can very quickly eat up and destroy a tire when driving too long on an imbalanced tire/s. Carefully check the tires tread for uneven wear patterns and more specifically any tread height differences such as cupping and irregular tread block wear patterns.

    Once the tire has become damaged.. there is nothing that balancing after the fact can do to restore the damage. And unfortunately, once that damage has set in the carcass will continue to wear in an uneven fashion to promote future imbalances. No way to stop it even if you continually rebalance them in shorter time frames. This is also part of the reason why insurance companies will write off a seemingly good set of tires if the car was involved in a skid type collision. The tires will have suffered slight flat spots and will continue to wear irregularly and always makes noise from that point onwards.

    I've flat spotted several sets and can personally attest to the difference a new set of tires will make. Beyond that, work on your driveline angle.

    The right questions to be answered. In addition to illness - cures listed, I've also experienced worn tires or tires coming apart on the inside and warped rotors.

    back in the day (70s), tire stores had a machine that could "cut" a new face on unevenly worn tires. haven't seen one of them in years, seems like all the stores stopped doing it at the same time...:huh:

    That's definitely a new one on me. Seems similar to the machine they use to prep the carcass for retreads. Sounds reasonable for damaged tread but still wouldn't do squat for separated/damaged belts though.

    Guys use to do it to brand new tires to "true em up" before balancing too. Here's a video of the machine in action...
