How to Disassemble a Strut and Replace the Shock

How to disassemble and replace the shock on a strut assembly. For this I am using the rear strut off a 1997 BMW 540i as an example. As you can see here is the strut assembly, the shock will be getting replaced as the mounting point has cracked. For This I am using a spring compressor, I would recommend only purchasing a quality made tool as some no name or economy brands have poor quality control so the tool can fail during operation which can result in an injury. #oemtools #suspension #autorepair Impact wrench: https://mobiledistributorsupply.com/2...

The spring needs to be compressed, so the depressed portions of the jaws will face each other. Then install the threaded jaw and at least 2 inch of the threaded rod should be exposed before going into compression on the outside just as safety. This particular compressor has retaining pins to hole everything in place and it’s certainly a nice feature to have so nothing slips out of place. Pull the pins back before putting the jaws in place. While maintaining that 2 inch safety with the threads, we still want to try to compress the spring at the furthest points. The larger area you pick to compress, the less strain it is on the compressor and also the spring. Insert the other pair of jaws. The pairs of jaws must be directly across from each other, otherwise they won’t compress the spring evenly. Engage the safety pins so the jaws can’t pop out of their location. Use the appropriate sized socket and compress the spring. Try to be as even as possible between the two compressors. Once the spring has the removed the tension on the strut assemble, you’ll notice the shock becomes loose and easily movable. You’ll want about a 1/4” of movement. It’s enough to know the spring tension has been remove, but not too much where you put the tooling under excessive pressure. In order to remove the upper spring seat, it’s held on with a retaining nut on the center which is connect to the shock shaft. Never remove this nut while the spring has tension on the strut assembly. You can get severely hurt. Technically you can use a couple wrench for disassembly. One to hold the shock shaft from spinning and the other to remove the nut. Instead I’m just using the impact wrench which normally has enough force to spin the nut off, but sometimes the shaft will spin so use pliers to hold the shaft. If you are keeping the strut, do not use pliers as this can damage the plated surface which will eventually create a seal failure, requiring a shock replacement eventually. You can slightly loosen the nut and should notice play in the upper spring seat assembly or at least a space between the nut and seat assembly. Here is the nut once removed, the new shock should come with a new locking nut. Remove the retaining cap. Then remove the upper spring seat. Unfortunately the bump stock is still stuck in place due to the spring compressing tool, so they’ll need to be loosened and removed. Once the clamps have been removed, pull out the assembly. Pair up the old and new shocks, ensure they are the same. First installing the rubber spring pad. Then the coil spring. Next is the bump stop, this can go on before or after the coil spring, doesn’t really matter. The coil spring. The upper spring pad. The spring pads will sit in certain spots where the coil ends. Reinstall the spring compressor in the same procedure as before. Compress the spring until you can get the retaining cap and enough threads for the nut to have full contact. I normally like to install the nut as a form of safety, continue to compress the spring, then tighten the nut accordingly. As you can see I am able to use the impact wrench to tighten the nut this time around as the shock is new, so there is more resistance so the shock shaft doesn’t spin as easily. Ensure everything is lined up and seated correctly, then remove the spring compressor evenly. Now the strut assembly can be reinstalled back on the vehicle.
