A toolkit to replace the front lower Control Arm Bushing vertically includes items such as Control Arm Bushing set (J 21474-01) and 1/2 inch puller bolt thrust bearing (J 21474-27) and bushing installer remover (J 21474-2) alongside nut (J 21474-4) along with Control Arm Bushing installer (J 21474-13) and high pressure lubricant (J 23444-A) and driven sprocket support bearing installer (J 34126) and front knuckle support (J 35379). Multiple replacement components are required including Control Arm Bushing set (J 21474-01), 1/2 inch puller bolt thrust bearing (J 21474-27) and bushing installer remover (J 21474-2) along with nut (J 21474-4), Control Arm Bushing installer (J 21474-13), high pressure lubricant (J 23444-A), driven sprocket support bearing installer (J 34126) and front knuckle support (J 35379). Begin by placing the lower Control Arm into a vice for stability while performing the next steps. Begin by marked the lower Control Arm along its flat bushing flange surface. Lock out j 21474-27 threads with j 23444-a before threading j 21474-27 into j 21474-2 and j 21474-13 and j 34126 and j 35379. Then apply j 21474-4 until the tools are disassembled. Begin by tightening j 21474-4 then disassemble the tools using j 21474-27, j 21474-13, j 34126, j 35379, j 21474-2, and j 21474-4. To create a proper install position the lower Control Arm vertical bushing should align for original ride characteristics and handling behavior and road feel preservation. Align the bushing flange flat edge against the arm's marked area with a 30 degree angle from the centerline so the bushing's narrow slot points toward the exterior. Put the bushing inside the Control Arm then apply j 23444-a lubricant on j 21474-27 threads before tool assembly: before tool disassembly install j 21474-4 with a torque setting while using j 21474-27, j 21474-13, j 21474-4.

To replace lower Control Arm bushings, one will need the following tools: Control Arm Bushing service set (J 21474-01), a nut (J", 21474-4 high-pressure lubricant (j 23444-A), puller bolt (J21474-27); bushing installer (l j 21474); bushing installer (j21 474-2, and Front Knuckle Support ). J 35379). Start by taking out the lower Control Arm and clamping it to a vice. Mark the lower Control Arm along the flat edge of bushing flange and assemble the bushing removal tools. Puller bolt (J 21474-27), driven. Sprocket support bearing installer (J 34126), front knuckle support (J 35379), bushing installer (J 21474-2), and nut (J 21474-4). Combustion chamber is the term that refers to the part of the engine where the air and fuel mixture comes together for nearly instant combustion. The combustion chamber is primarily the area that lies between the piston head and cylinder head. The head is the part of this engine facing upwards when the engine is in its horizontal position. Therefore, the combustion chamber should lie above the piston crown, and at the centre, it should be close to the valve. Disassemble the bushing removal tools. For installation, put the flat of the bushin flange to the mark on the Control Arm, 30 degrees to the centerline, thin slot of the bush in and outboard. Place the bushing in the Control Arm and now assemble the bushing installation tools. Puller bolt (J 21474-27), driven sprocket support bearing installer (J 34126), bushing installer (J 21474-5), nut (J 21474-4). Again, apply the high pressure lubricant (J 23444-A) to the threads of the puller bolt(J 21474-27) and then tighten the nut(J 21474-4). Finally, pose apart the bushing installation tools and insert the lower Control Arm.

The first step begins by removing the lower Control Arm then securing it into a vise for installation work. The bushing puller requires you to use a standard thread 1/2 x 20 in nut and puller bolt. The nut must be paired with the Control Arm Bushing service set (J 21474-01) washer , Control Arm Bushing service set (J 21474-01) bearing , Control Arm Bushing receiver (J 21474-5) and Control Arm Bushing service set (J 21474-01) puller bolt to form the bushing removal tools. Tighten the puller bolt until it removes the bushing and separate the j 21474-01 from the j 21474-5. The new bushing needs liquid hand soap or similar lubrication before being installed with the designated 1/2 x 20 in standard thread nut attached to the puller bolt. You should assemble a set of bushing installation tools which include the nut, Control Arm Bushing service set (J 21474-01) washer, Control Arm Bushing service set (J 21474-01) bearing, Control Arm Bushing receiver (J 21474-5), and Control Arm Bushing service set (J 21474-01) puller bolt. Continue bolting down the puller tool after the bushing inserts into the Control Arm before you disassemble j 21474-01 and j 21474-5 and remove the Control Arm from the vice for lower Control Arm installation.

To perform vertical lower Control Arm Bushing replacement one requires these tools: Control Arm Bushing set (J 21474-01), 1/2 inch puller bolt thrust bearing (J 21474-271), bushing installer remover (J 21474-2), nut (J 21474-4), Control Arm Bushing installer (J 21474-13) and high pressure lubricant (J 23444-A) and driven sprocket support bearing installer (J 34126) and front knuckle support (J 35379). The tools required for vertical lower Control Arm Bushing replacement include Control Arm Bushing set (J 21474-01), 1/2 inch puller bolt thrust bearing (J 21474-271), bushing installer remover (J 21474-2), nut (J 21474-4), Control Arm Bushing installer (J 21474-13), high pressure lubricant (J 23444-A), driven sprocket support bearing installer (J 34126), and front knuckle support (J 35379). First secure the lower Control Arm into a vice before proceeding. Draw a mark on the lower Control Arm right along its bushing flange flat surface. Steadily apply j 23444-a or equivalent to the threads of j 21474-27. Assemble the bushing removal tools: the installer assembles tools in the sequence of j 21474-27, j 21474-13, j 34126, j 35379, j 21474-2, and j 21474-4 before tightening j 21474-4 to separate the tools. When installing the lower Control Arm vertical bushing verify its placement which preserves the vehicle's original ride performance alongside handling characteristics and natural road feedback. Position the flat bushing flange against the Control Arm mark at a 30-degree angle from the center and direct the bushing's narrow slot towards the outside. First place the bushing into the Control Arm before applying j 23444-a lubricant to j 21474-27 threads then connect the installation tools in this order: j 21474-27, j 21474-13, j 21474-5, j 21474-4. J 21474-27, j 21474-13, j 21474-5, and j 21474-4. With j 21474-4 as the final tool, disconnect all tools before adding the lower Control Arm to its place.

In order to substitute the lower Control Arm bushings, first take off the lower Control Arm and clamp it in a vise. Mount in a 1/2 square nut standard thread with a puller bolt (J 21474-01 puller bolt ). Put together the bushing removal tools, the bushing removal tools comprise of the follows; the nut, j 21474-01 washer, j 21474-01 bearing and the Control Arm Bushing receiver (J 21474-5) (Siemens 2011). Tighten the puller bolt until the bushing is removed then deassemble the j 21474-01 and j 21474-5. For installation, lubricate it with liquid hand soap or an equivalent then use a 1/2 x 20 in standard thread nut with the puller bolt (J 21474-01 puller bolt ). Assemble the installation tools, comprised of the nut, j 21474-01 washer, j 21474-01 bearing, and the Control Arm Bushing receiver ( J 21474-5 ). Tighten the puller bolt until the bushing is install into the Control Arm, disassemble the j 21474-01 and or the j 21474-5, wipe out the vice and thus eventually install the lower Control Arm.
