Prices to replace engine mounts vary with the vehicle, the price of the mounts and the labour costs. Generally, the cost runs between £227 to £357. The mounts can be purchased relatively cheaply online, but many dealers or mechanic shops won't guarantee the work unless the parts are purchased themselves wholesale through suppliers (you'll pay the retail price). There are many mounts available at motor parts dealers online for substantially less than you would pay through a dealer. The cost of installation itself, though, varies, as well.
Why Replace Engine Mounts
The motor mount is a rather simple component, but is necessary to keep the car from bucking and wrecking all kinds of other parts that make your car run. Without a solid mount, the engine would shift somewhat violently in the engine compartment causing damage and ruin connections to other components. And that doesn't even address how the ride or feel of the car would be compromised.
A Simple but Vital Component
The motor mount is constructed of steel and is equipped with a heavy rubber insert to help absorb the strong engine vibrations. It essentially isolates the vibrations from the vehicle chassis to prevent the shaking from being carried throughout the vehicle. Not only does it make the ride smoother, it protects other sensitive components that could be prematurely damaged.
Rule of Thumb
The more expensive the vehicle, the more expensive the repair. At least that is usually the case. All car parts break down over time. If you drive a junker, you can probably find an engine strut for $25 to $50 dollars. If you want to replace it yourself, you've just saved a lot of labour costs. If you're driving a top-of-the-line Mercedes, however, the chances are you aren't going to a junkyard, you're taking it back to the dealer, and dealership prices are usually on the higher end of the scale. That would put you back into the £325 range.
If you live in an isolated location, there most likely aren't too many dealers or mechanics to replace your motor mount. As a result, there isn't much competition and therefore the price to replace just about anything in your car rises. Take the Central Coast of California, for example. The difference in cost just to run an electronic diagnostic on your vehicle can vary by as much as 100 per cent. Compared to highly populated areas, where there is competition for your vehicle maintenance, the costs are much more comparable and generally less costly. The same holds true for your motor mount.
Your Best Bet
Find a local reliable mechanic who is willing to install the mount. Purchase the mount on the Internet, where prices are often much better than the retail prices you will pay from a dealer or even the local mechanic. Depending on the vehicle and depending where you buy the mount, you've cut your costs significantly. If you're a weekend warrior and capable in auto mechanics, it's not that difficult a job but do expect to spend at least a day, maybe two, to do the replacement yourself.
