What wheels? If they're aftermarket, are they hub centric? Correct lug seats on the lug nuts?
I have an 2003 Jetta 24V VR6 Tiptronic. Vibration started before changing both axles to raxles, ball joints, vf mounts, bearings are good and no movement, new tires less than 30 miles on them, Every nut and bolts are within torque specs. Transmission flanges/axle are in excellent shape. Vibration starts at low speed at 2mph and increases when speed increase...almost like a bubble on the tires. Using Bilstein Pss9. Many thanks.
Have you had your wheels balanced recently? Sometime the weights can come off. Also check the bushings. I know you've stated that they were changed to HD, but that was 4-5 years ago. With our crappy roads and weather they could have deteriorated by now.

A little more on track how has it been working w/ Stuttgart. Its been a week any progress?
All bushing was replaced a few years ago every suspension components are in excellent condition. I talked to Marty at Raxle and gauranteed that the axles are not the cause of the vibration and Gary and Raul agreed since they tried another axle and the vibration are still present. Raul mentioned that the engine may have shifted towards the driver side binding the axle joints when loaded. When car is on jack no hint of a vibration since the axle have some play. His going to make the adjustment tomorrow and see if that works.
The rotational vibration is notcaused by a the axles from raxles. The engine shifted toward the left side after many years of driving. A couple of causes, the rubber motor mounts deteriorates on the driver side, leaking silicone filled motor mounts on the passenger side. New axles do not have wear on them since the joints are replaced new vs. worn cv joints. In addition with the new axles are put into placed, it is a fraction longer and the edges are still new. So, with a lowered car this tend to bind. When the car was on the lift no vibration is detected due to the suspension being relax or no load on the suspension and no load on the axles. When the car is on the ground the suspension has a load against it therefore the axle bind (loaded) = the vibration. To remedy this problem move the engine towards the passenger side as much as you can (in my case) and coil up...raise the front. This is a common problem with a tiptronic trans. Marty at raxles sway people of lowering their VW with tiptronic due to the binding complaints on lowered VW. I have driven my Jetta for 7 years now with 106K miles in the odometer with PSS9 coilver and after changing the axles it started vibrating. With the option of raising my car's coilover the vibration stops. I'll wait and see after a few 1k miles i'd lowered her again. So I learned something that rotational vibration is not cause by a the axles but other components within the system. Marty from raxles may one day built a special axles for tip cars when there is a great demand for them.
