A car bumper serves both cosmetic and practical purposes - being part of the body design, it protects it from damage. That is why during operation vehicle this item quite often gets damaged, suffering even from the lightest frontal car impacts, not to mention serious collisions.
If you removed the tape, then the rubber may be further worn in the profile. If you don't have the right build tools, take a look. Steel chrome plated or stainless steel? Rumors circulate that stainless steel bars have a strong yellow tint or don't have much in common with chrome.
Stainless steel is not bad as the alloy is good and the finish is correct. American models have far protruding bumpers, which are rather unpopular in Europe. If you have this, before you need a special conversion kit, which is offered in various versions on the market.
Replacing or repairing a bumper is an eternal dilemma for motorists who have been in an accident. Oddly enough, in addition to the cost of the part, the choice of a method for solving the problem is more influenced not by the nature of the damage, but by the material of the product - plastic or metal.
Today, 90% of modern cars are equipped with plastic bumpers.
The reasons are obvious - relatively low cost and ease of manufacture, high rates wear resistance. Non-critical flaws are easily eliminated by simple heating, straightening or gluing. At the same time, the cost of repair compared to replacement will be quite small. In cases serious damage often recovery is not possible, and the only solution to the problem is replacement.
The bumper holders should be made of spring steel, which will deform again in the event of a slight impact. But there are holders on the market that are made of mild steel and are not deformed by small nicks. The various conversion kits are then adventurously attached partly with self-tapping screws or a welding machine to the cross member.

Metal bumpers can also be brought back to normal after an accident. During repair, they are also subjected to straightening and updating of the coating (by grinding, polishing or chrome plating). But, frankly, it makes more sense to replace a damaged metal bumper, since restoration procedures are most often costly. more expensive than buying and installation of a new product.

Removal and installation of bumpers on the VAZ
For a complete understanding of what service centers charge money for, let's take a closer look at the replacement process using the example of a VAZ-2114 car (and its modifications VAZ-2115). The procedure is carried out using a key on "10", sockets on "13" and on "10", an extension cord, a wrench and a screwdriver with a Phillips blade.
Selection of new bumpers
Below is the meaning of each code. Builder Plate: It is located on the front panel in the top lintel. Engine type and number: Recorded on the engine block on the left side. Figure 01 - Location of vehicle identification plates.
These materials can be repaired with the appropriate technical procedures providing a good aesthetic finish. The figure below shows the repairable plastic elements, which, due to their location, can be broken in the event of a collision, as well as the identification of the plastic that will be used in their repair.
Front bumper
Before starting to dismantle the deformed part, remove the front fender liner, remove both fog lights and remove the license plate.
Next, two bolts are unscrewed, with the help of which the bumper lining is attached to the amplifier. During their extraction, it is necessary to inside hold the bolt nuts with a second wrench. After that, it is necessary to unscrew the two nuts responsible for attaching the right and left cladding brackets to the mudguard of the body
Figure 02 - External elements made of plastic. Verification and control of possible deformations in the structural elements of the vehicle body subjected to high forces must be controlled by checking the dimensions and dimensions of a series of one-piece points, such as suspension attachment points, towers and floor. These measurements were made using established mechanics.
Checking the dimensions in the upper part of the body was carried out using a rod compass, checking the equality of measures of its shapes between the pieces of the left and right sides. Figure 03 - Outer case dimensions. Note: Measurements in mm Figure 04 - Vehicle span dimensions.
The next step is to remove the cladding mounting studs from the holes located in the mudguard on both sides, remove the two bracket mounting nuts and remove the bumper beam. If necessary, the left and right brackets are also removed, for which two bolts are unscrewed and the nuts fastening to the body are unscrewed.
Removed and new parts are installed in reverse order.
