Bushing Replacement



All Mazda-s use a pressed in control arm bushing, and the pressing can be done using two appropriately sized sockets (a press socket and a catch socket) and a large bench vise.

  1. Position the control arm and the 2 sockets into a vise.
  2.  
  3. Position the press socket onto the control arm bushing.
  4.  
  5. Position the catch socket onto the control arm, opposite of the press socket.
  6.  
  7. Tighten the bench vise slowly and press the bushing into the catch socket.
  8.  

To install:

  1. Apply soapy water to the new control arm bushing.
  2.  
  3. Position the bushing against the control arm.
  4.  
  5. Using the same sockets, in the same positions, press the new bushing into the control arm.

    suspension support, dust seal, spring seat, spring insulators, coil spring and bumper
     

  2.  
  3. While pushing on the piston rod, be sure that the pull stroke is even and that there is no unusual noise or resistance. Also inspect for any oil leakage around the piston rod.
  4.  
  5. Push the piston rod in, then release it. Be sure that the return rate is constant.
  6.  
  7. If the shock absorber does not operate as described, replace it.
  8.  

To assemble:

  1. Install or connect the following:

    strut assembly into a vise
     
    bump stopper and dust boot onto the piston rod
     
    Temporarily install the upper spring seat, seat rubber and spring. Mark the seat, shock and spring assembly as illustrated for reassembly. Align the marks of the upper seat and coil spring. Protect the assembly with cloth and install the spring compressor.
