Replacement of silent blocks of the substrate Kashkai J10
Content
The subframe silent block is the most important part of the Qashqai suspension, connecting the front arms to the subframe. Due to the rubber and metal joint design, the arm can move up and down.
According to the recommendations of the manufacturer Nissan Qashqai, the replacement of these parts is necessary after 100 km of run. However, despite the hackneyed stamp “in the conditions of Russian roads”, drivers are often forced to come to a car service 000-30 thousand kilometers earlier.
Qashqai J10 subframe silencer blocks
The wear of the silent blocks of the subframe affects the behavior of Qashqai on the road. The loss of rubber from the hinge impairs stability on a straight road and when maneuvering, and damage to metal parts can have more unfortunate consequences.

Without high-quality diagnostics, it is impossible to determine the malfunction of this Nissan Qashqai suspension component. But there are a number of signs that allow you to determine that this node needs to be replaced:
- a creak in the front of the car, often when speed bumps pass”;
- increased fever;
- decrease in controllability and response to driving;
- knocking on large potholes;
- uneven wear of rubber and the impossibility of fixing the corners of the wheels.
Tears and other physical damage to the silent blocks make themselves felt with a loud clang caused by the impact of the subframe. In especially neglected cases, a piece may fall on the amplifier.

Necessary parts and tools
The silent blocks of the Nissan Qashqai subframe are not an expensive part, so you should not look for substitutes, but buy original spare parts. This guarantees a long service life of the assembly and prevents premature wear of the levers. The only reasonable exception to buying a non-original part is the installation of polyurethane bushings to give the car even more rigidity and stability on the road. However, remember that polyurethane creates an additional load on the rest of the suspension elements.
Front subframe bushing 54466-JD000
To replace rubber-metal bushings Nissan Qashqai you will need:
- 54466-JD000 - Front (quantity - 2 pcs);
- 54467-BR00A - Rear (quantity - 2 pcs);
- 54459-BR01A — Front bolt (qty — 2 pcs);
- 54459-BR02A - Rear mounting bolt (qty: 2 pcs).
Rear subframe bushing 54467-BR00A
It is worth noting that some Qashqai, released between 2006 and 2007, had an unpleasant design feature: they do not have a rubber (insulating) sleeve that limits the vertical movement of the subframe. Therefore, at the diagnostic stage, it is worth finding out the presence of these washers, otherwise they are purchased in advance:
- 54464-CY00C - Rear insulator (qty - 2 pcs);
- 54464-CY00B — Front insulator (quantity — 2 pcs).

From the tools you will need:
- hammer, weighing at least 2 kg;
- ratchet heads 21, 18, 13;
- necklaces (large and small length);
- asterisk on 19;
- wrench for 14
- pliers with curved jaws;
- screwdrivers;
- ½ inch l-wrench and extensions;
- Jack;
- ratchet head 32 (used as an alternative to the crimping mandrel).

Having prepared the necessary tool, you can begin to replace the silent blocks.
An overview of the Qashqai in use is in this text.
Removing the stretcher
The process of replacing the silent blocks of the Nissan Qashqai subframe part begins with hanging the front of the car and removing the wheels. After that, you need to disconnect the stabilizer links. You can disconnect them both from the stabilizer and from the shock absorber.
The steering rack mounting bolts are marked in red, the lower engine mount in blue, the cross bolts in green
In this case, it is important to remember the location of the stabilizer relative to the subframe. This will come in handy for final assembly.
Then the protection is removed, which is attached with a large number of clips. The clips are broken off with a screwdriver and removed with pliers. The subframe is attached with four bolts. First of all, you will need to unscrew the two screws that hold the front silent blocks. To disassemble the rear, you need to unscrew the steering rack that is attached to it. Fastened with two bolts size 21. For more convenience, it is recommended to fix the rack with a cable on the exhaust pipe. Also, an obstacle when removing the subframe element is the lower engine mount, which can be easily removed with a key of 19. Before starting work, it is also advisable to check the condition of the mount and, if necessary, replace it with a new one.
Remove the subframe, unscrew the suspension arms
After that, the cross member (ski) is disassembled by unscrewing six screws, the first of which is the front four. The remaining two are the bolts for attaching the rear silent blocks.
The loose subframe is held in place by special rubber bands that keep it suspended.
After that, you can proceed directly to the removal of the subframe by removing it from the rubber bands. First you need to disconnect the levers attached with three bolts. They are unscrewed with keys 21 and 18, using pre-prepared extension cords, the length of which is about 65 centimeters. To prevent the subframe from falling, it is worth using an additional jack.
The final part of the subframe disassembly: unscrew the bolt marked in green
When removing the subframe, be very careful that the stabilizer does not catch on the braces and damage them. To do this, as it is removed, the stabilizer must be rotated in the bracket.
After disassembly, the assembly moves to a convenient place to replace the silent blocks.

Repressing the silent blocks of the stretcher Nissan Qashqai
In the absence of an extractor, silent blocks can be knocked down with a sledgehammer. To do this, a piece of pipe with a diameter of about 10 centimeters is placed under the subframe. A head for a ratchet with a diameter of 43-44 mm is inserted from above. Head size 32 fits best. Then several tight blows are applied with a mallet and the rubber-metal bushing comes out of its seat. To extract the front silent block, its own inner part is used as a mandrel. The steps are the same as for the back loops.
Pressing out old silent blocks
To press the silent blocks, they must be lubricated with graphite grease. The subframe is turned over, a pipe is installed under it. The next task is to screw the rubber and metal bushing into place. For this, a pipe segment is also used, which is put on the silent block. You need to start hammering the spare part with light blows, gradually increasing the applied force. This process is laborious and takes a little longer than pressing.
All Qashqai subframe bushings are pressed in the same way.
Pressing new subframe bushings
Having finished work with the subframe, it is installed in its place. Suspension assembly is carried out in the reverse order.
Conclusion
Replacing the subframe silent blocks with a Nissan Qashqai, although a rather laborious process, is even possible for a person who does not have much experience in car repair. True, in this case, the procedure will take 6-12 hours. So if you want to save money, learn more about the gimbal device, or just do it yourself, then you can do it.
