When to replace mounts?
A simple rule of thumb is that if the struts or coil springs are being replaced because of age or wear, then also replace the mounts. A worn or damaged mount can cause a variety of symptoms so they should be carefully inspected. Disassembly of the entire strut & spring assembly is required to remove & replace the mount. Therefore replacing all worn components at the same time could save you from doing the work a second time.

How to tell if the mount is worn:
• Drivability symptoms may include:
• Clunking noises
• Vibration
• Loose, stiff or noisy steering
• Tire alignment
• Tire wear

Visual indication of a worn mount may be:
• Loose or damaged components
• Excessive movement
• Cracked or sagging rubber
• Corrosion

Installation Tips

Some Strut Mounts have adjustable "clock" position insulators. During installation, what sometimes appears to be a mis-positioned welded spring seat may actually be caused by the need to reposition the upper mount rubber insulator.

To install some struts it may be necessary to rotate the upper strut mount insulator which can be separated from the mount. The directions are as follows:

  1. Make a mark on the upper mount in line with (depending on the model) the notch in the strut pinch bolt area or the steering knuckle bracket.
  2. Disassemble and loosen the spring compressor so you can remove the mount and insulator.
  3. Separate the rubber insulator from the underside of the mount and then put the insulator back onto the spring so that the insulator matches the spring position.
  4. Put the strut back into the spring and put the mount onto the insulator.
  5. Align the mark on the mount to the notch in the strut or steering knuckle bracket.
  6. Compress the mount and spring assembly, install and torque the strut nut to OEM specifications.
  7. Reinstall the assembly.
