How to Lube Upper Bolt for Strut Mount Replacement

Disassembling the strut correctly is extremely important in the proper functioning of your vehicle's suspension system upon reassembly. Part of this disassembly will require the strut mounts to be replaced and the upper bolt to the strut mount to be lubed. This is done not only to clean up the strut, but also to salvage a couple of parts that do not come with the new strut mounts.

Difficulty: Easy

Instructions

1. Purchase the new strut mounts and notice the difference between the new and old strut mounts. You will likely find the old strut mount to be extremely corroded and flaking apart. The retaining nut is important to clean up and save, because a new one will not come with the new strut mounts. You can purchase one separately.

2. Remove the strut mount from the vehicle, but leave it assembled. Set somewhere that is clean of debris and dust, but can catch lubricant or other fluids for proper disposal, like an oil pan or other container.

3. Fill the entire strut galley with a penetrating oil or other penetrating lubricant. These could include WD-40, PD Blaster or Liquid Wrench. This will break away the corrosion and allow it to fall away from the upper bolt and other components of the strut.

4. Allow oil to sit for awhile in the strut galley in order to allow it time to work and remove the corrosion. Dump out the fluid into an oil receptacle for proper disposal and rinse the strut to remove the loose corrosion and debris.
