Loss of Traction After Alignment

I hope someone can assist. I have a 1995 90 Quattro Sport (82K miles) in mint condition. Last week I replaced a wheel bearing on the rear passenger wheel and did an alignment as well as after the wheel work, the steering wheel was off center by 20 degrees.

Since the wheel/bearing/alignment, the car seems to "drift" and feels like a loss of traction. While the car tracks straight, at times the car seems to feel like it will loose traction at anytime. This has never been the case prior. At present, the car does have snow tires on it (Colorado Mountains), however, did not have these issues prior.

Could it be the bearing, the alignment or both. Any insights would be appreciated as I am now fearing driving the car. Thank you,
