Does the TT Use a Pin Adapter on a four point lift arm that fits into those rubber cushioned donuts alongside the sill jack points?

I did a tire rotation in the drive way (one side at a time) and after I got done I got some wheel noise right away. tried re-torquing everything, no joy. it sounds like a wheel hub bearing is going bad. i just can't understand how rotating the tires would ruin a bearing. Any ideas?

Sure you rotated the right way?

ThanosNaranja

Front to back right - they're radials...

Any unusual wear on the tires?

Just discussed recently, the rubber pads are fine for jacking.

cause the noise. If it's really bothersome, reverse the proceedure, restoring the tires to their original locations. If the noise quits, you know your wheel bearings are OK, and it's just the tires. I'd probably just leave them if it quieted down, run out the rest of their useful life, and purchase new. Is the small increase in tire mileage worth the aggrivation of the noise??

Left and right swerves / lane changes... this often gets the tyres settled into their new front location
I had the same problem, it really can work!

I was amazed by an Audi "factory" fix that showed up on the A6 board for tire noise. Temporarily rotate in an X pattern. Left rear to right front, etc. So the tire rotates the "other" way. It supposed to quiet them down. And yep, they meant this to be used with directional tires!!! hmmmm?

Fixed my Pilot Sports when they really loud at speed... and I do mean VERY hard & sharp !

I'm retired Navy and so I have access to a full four point shop lift at the base auto hobby shop. i went over and put it up on the lift. and checked the whole suspension system wheels for belt or wear problems controls arms rod ends frames bushings etc. and could find nothing unusual or out of the ordinary and everything was tight. I've tried the slalom (Audi Rep Suggestion) and I've been driving on them for two weeks no joy

I thought I would include some pics I snapped with my phone (hope they turn out okay).

There are a set of rubber padded adapters that are available for the four point lift. I used them on the rear lift points because the rubber donut is located so deep in the surrounding frame work and I was concerned that the standard steel foot-pads would contact the surrounding sheet metal structures. The amount of front end tilt when on the lift definitely gave me the ******* at first, but it didn't go anywhere. I definitely agree that these lift points should not be used singly to lift a corner of the front end. Too much weight, but people will do what they feel comfortable with I'm sure.

I also noted that the Audi tech bulletin listed elsewhere in the forums is no longer valid so here is a good location:

in closing I am pretty sure there is a 50% chance that there is a front hub bearing going bad. But what should I do? take it apart with no assurance its bad? it only seems to make the noise under load and worse when the car is turning into the left front tire, which probably means that's the bad bearing. And if its not/ may as well wait a while and see if it gets worse.
