The fender on your Mercedes Benz 300D's primary function is to keep dirt, debris, and other particles from the wheel and the braking system. Over time, dirt buildup will cause corrosion and rust holes, which will compromise the part's durability. If you suspect that the stock fenders are already wearing and tearing, then you had better perform some troubleshooting. Listed below are a few common problems encountered with defective Mercedes Benz 300D fenders and the reasons behind them.
A common defect encountered with metal parts is corrosion. Over time, the fenders on your auto may exhibit signs of rusting. This can be a result of aging parts or by improper cleaning and maintenance. In other cases, you may cause premature rusting by constantly driving through puddles of water. Failing to wipe off wet parts can increase the rate of wear and tear and can greatly decrease the fenders' durability. To check for rusting, simply inspect the fenders for rust holes. Be sure to check the inside parts as well because they can be hidden from view. It's a good thing addressing rust is easy. Simply remove the loose rust with sandpaper and apply some rust dissolvers.
Most cars are designed with an easy-to-remove fender because fender bender is a common case. If you recently experienced a minor collision and the fenders have been damaged, then your best option is to find a replacement. Even if you have not been in a collision, there are several instances where the fenders can get damaged. There are cases when fenders are bent because of improper parking, or other drivers may have simply miscalculated and accidentally hit your auto. Attempting to repair them back into shape may cause several other defects like rim or tire damages, so your best option is still to find a replacement for the stock part.
Rim damage is often a result of unaddressed fender benders. They are easily detected when driving because of an unusual vibration in the steering column. If this happens, check if the fenders come in contact with the rims. They should be replaced immediately to prevent premature tire wear.
