Hello -- Wondering if someone could help me figure out if this is the correct part for my S70.

My mechanic recommended part #272456 (Wheel Hub Assembly) to replace both of my front bearings. This is the part here: 272456 in Canada | AutoPartsWAY.ca

However, I have found a much cheaper part, but the part# is different. This part is also a Wheel Hub Assembly, but the part # is 513175 (Transbec Edge Front Wheel Bearing) from this site: Search for VOLVO 513175 - Autopartsfreak.com | 216.1157

If I ordered that second part (513175), is it the same as the part my mechanic quoted me on? Just wanted to be sure before I order it :-)

Thanks!
Jeff
