Online, the opinion differs from one website forum to another, so there is no clear answer. In the United Kingdom, most people say the price does vary depending on the garage or mechanic you choose to go to. One person claims it cost her £106 for the labor and the part, whereas another paid £290 for both wheel bearings to be fitted (parts and labor included). Although another claims they only paid £100 for parts and labor.
In the USA, prices online seem to vary from around $185 to $200 depending on the mechanic. It is therefore worthwhile to ring around a few garages first to gauge the average price and then you will be in a better position to make a decision. There is no point in just taking the car to the first garage you speak to as there may be a chance of getting a better and more reliable job carried out elsewhere for much cheaper.
There is also the option of buying the wheel bearing parts and fitting them yourself, or. You could take the parts to the mechanic and then just pay for the labor. Again, prices will vary from one garage to another, so ring around first. There are a few websites online where you can buy and compare prices for parts. One example can be found at this link:
