My rear tire on my audi a6 2.7tt quatro is not straight what is bent?

where does it leak from, investigate, you may need to tank, could be hoses. Unable to investigate take to repair shop.

If your model is not quatro , then it may be wheel bearing or uneven worn(rough) tire.

Your Checklist

The alignment was poorly done
You need new brake calipers, the right one could not be letting go
Get the Rims Checked they could be bent
Did you also align the rear wheels
Tires - Condition / Quality
Bent Rims
The new tires you purchased.....are you sure they were first grade and not second grade tires?

This is a manual transmission? If so the clutch probably needs to be replaced. When you say "VIOLENTLY" what is going on, what is the road speed, what are the RPMs at? The more specific information the better. And this problem ONLY occurs between gear changes, right? The other times, everything is normal?

Sounds like universal joints going out.

It's good to shop around for new tires, the mechanic may not have a good deal from the supplier. Therefore, he needs to charge more. Just shop around in your area for better deals on tires.

As for the other repairs, the first thing you'll need to get done is the front lower control arm ( the worn ball joint ). Worn out suspension parts will cause premature wear on the tires. Because, it would not be holding the tire steady and it would be basically " out of alignment ".
If I remember correctly, the whole control arm would have to be replaced, because the ball joint isn't changeable in the control arm. I believe that's why he's asking $700.
The mechanic again probably doesn't have a good deal on his parts supplier. I think it's too high myself. I would call around other shop for better prices. Other shops that have better deals on their suppliers will usually pass the saving to the customer.

If you have an Audi Q7, locate the "Car" button on your console, the screen will prompt you to check settings, select TPMS and then select new tires, this will recalibrate your TPMS.

Hope this helps.
