2005 Cadillac DeVille Parts Questions & Experts Answers

• Q: What tools are required to service and repair the front coil springs and shock absorber on 2005 Cadillac DeVille?

  A: The suspension strut repair and servicing operation requires three main tools: service tools needed for suspension strut work comprise strut rod nut socket (J 42991) and strut spring compressor (J 45400). Strut rod nut socket (J 42991) and strut spring compressor (J 45400). First step is to remove the strut from your vehicle. Set the strut inside the strut spring compressor (J 45400) while the spring remains compressed during free strut movement. The spring compressor requires multiple turns until complete spring compression happens. Install a 45 torx socket to secure the strut shaft and use the strut rod nut socket (J 42991) for upper strut mount nut removal. The strut spring compressor (J 45400) requires users to remove the strut before they proceed to loosen the compressor forcing screw for upper strut mount and coil spring retrieval. The strut spring compressor (J 45400) requires the combined assembly of coil spring and upper strut mount before re-compressing the spring. Install your strut to the coil spring and upper strut mount before loosely applying the strut retaining nut while making sure you use the correct fastener in the correct position. Install the upper strut mount nut with a 45 torx socket and strut rod nut socket (J 42991) then tighten it to 85 nm (63 lb ft). The strut spring compressor (J 45400) should have the strut removed for reinstallation back into the vehicle.
