2000 Nissan Pathy - Needs cv boot, wheel bearing replacement

[Casutherland42]

Mechanic told me today that my front end will not stay aligned due to my wheel bearings going bad. On top of all that, I need to have my cv boots replaced in the front, and both front passenger and drivers side wheel bearings replaced in 4x4 2000 Nissan Pathfinder. Also, I need an oxygen sensor and AC clutch replaced. My mechanic is extremely good and cheap. He is Russian and known a TON about cars in general, so I am trusting him on these accusations.

However, my main question...Can anyone tell me where to purchase these parts. I want some good stuff with decent warrenty's for a good price. I prefer buying things online, simply to avoid tax, and normally get a better deal. Do you guys say I go with factory parts or aftermarket? Can someone provide me with links on a good place to purchase them? Or actually give me a link to the part EXACT. I am not sure what exactly I need to buy, but that is what he told me needs to be replaced.

A lot of people like RockAuto for getting parts... I like to stick with Genuine parts when price is not crazy more..

The inner and outer bearings are different parts and dont forget new seals. If they truely have failed to the degree that the wheel is wobbly then you likely going to need someone that can press out the old races and install the new ones.

Its not that my steering wheel is wobbly, but that i have to turn it at an angle to keep the car going straight. Ive had my front end aligned multiple times, and still am having this issue. He could also tell by the extreme wear on the rear and front tires that the alignment was off, basically due to bad wheel bearings according to him.
