Wheel Bearing

[jqjet]

I have a 2001 Boxster S that has only 37K on it and ive loved every mile! Bad news today that I need to replace a right rear bearing on the tire. I thought it was my Yokohama's that were making the noise but i was wrong. Dealer tells me $90 for the part. No biggie. Strangely couldnt tell me the labor which is a bit distressing. Ive asked him to hold off on work until he gives me an estimate.
(I really dont like this dealership and am thinking of changing or finding a non-dealer Porsche certified garage).

Anyone have a clue what I can expect for labor ? Ive looked around on the web and I found one estimate of 4hrs and another of 5. There seems to be uncertainty on the issue of an alignment being required. Ive seen more folks say no than yes to the alignment.

Any thoughts? Id really appreciate any information/experiences others have had with wheel bearings.

Thanks for any help advice
