How much would a front axle of a 2001 Buick lesabre cost?

The cost of replacing a part is a very general question that unless specified exactly is hard to answer. First, is who is replacing the part? Is the Dealer, an independent repair shop, a junkyard, the guy next door or you doing the replacement. These will all yield different prices. Not to mention that within all of these will be different labor rates and different part price mark ups. Second, what is the quality of the part? Is it a name brand, generic (white box, economy), OEM or used part? All of these will be different. Price will even differ between name brands, sometimes significantly. Thirdly, What is the warranty of the part and who is offering the warranty (the shop the parts house or the manufacturer). Limited Lifetime will have restrictions. Lifetime warranty isn
