The procedure for installing the front side door lock striker begins with shutting down the ignition and taking out the key to stop SIR activation and prevent personal injuries. Make installation marks on the striker using a grease pencil. First remove the bolts from the striker before taking it out. Fasten the striker bolts loosely to the striker before aligning it with the already marked reference points. After loosely installing the striker using bolts check the door closure while adjusting according to demands and finally tighten its bolts to 25 N.m (18 lb ft). Tighten the striker bolts to 25 N.m (18 lb ft). After removing the striker bolts the anchor plate can slide down from the door pillar until access to the panel opening requires removing the exterior trim.

Prior to working on the front side door lock striker the ignition must be turned OFF along with key removal because this will stop SIR deployment and prevent injuries. The striker requires markings with grease pencil before removing its bolts and the striker itself. Install the striker first by loosely screwing its bolts while keeping it aligned with the installed marks. First check door closing functionality then proceed to adjust the striker assembly if needed. Secure the bolts with hand torque and complete the strike replacement examination. Check the alignment properly before securing the striker bolts with a torque of 25 Nm (18 lb ft). Fastener guidance must be followed precisely to prevent vehicle damages.

You should start by taking out the front door lower striker bolt to begin installation of the component. The upper striker bolt should be loosened just enough to allow rotation of the striker together with the spacer if fitted so they move away from the lower bolt hole. Secure the lower striker bolt until it maintains the striker backing plate position. Start by removing the upper striker bolt and following it with removal of the spacer when it's present before proceeding with the upper striker removal. Start the installation process by attaching the striker along with its spacer before you put in the upper striker bolt . When the stripper backing plate shifts position it is essential to adjust the lower bolt rotation until both threaded holes align correctly. First remove the lower bolt and rotate the striker together with its attached spacer (if present) until the lower threaded hole of the backing plate aligns. The completion requires you to fasten the striker bolts at 24 N.m (18 lb ft).

The installation process of the front side door lock striker begins when you turn OFF the ignition and remove the key because these steps prevent SIR from being deployed which could create personal injuries. Draw markers on the striker with a grease pencil to serve as installation guidance. After removing all the bolts proceed with taking out the striker component. The striker should be loosely installed to its bolts before its alignment with the pre-made marks. Check the door closure and resize the striker before installing it properly. The last step requires secure tightening of the striker bolts to reach 25 N.m (18 lb ft) using the Fastener Notice specifications.

The procedure to replace the front door striker starts by taking out the lower striker bolt then loosening the upper bolt just enough for rotating both parts away from the lower bolt hole. Install the lower striker bolt until it achieves sufficient tightness which keeps the striker backing plate stable. After removing the striker bolt at the upper position you should next take out the spacer (if present) and finally remove the striker. The first step of installation involves installing the striker then its spacer if it has one along with the upper striker bolt. You should remove the lower striker bolt when the upper threaded hole needs re-alignment to the proper position. Before installing the lower threaded hole in the striker backing plate you should rotate both the striker and the spacer (if equipped). Users need to exercise careful protection when dealing with fasteners. The termination of striking bolt installation requires a final torque of 24 Nm (18 lb ft).

Begin the replacement of front side door lock strikers by ensuring you turn off the ignition then remove your key from the ignition because SIR deployment and injury risks will minimize. First mark the position of the striker with grease pencil before removing the bolts together with the striker. Begin installing the striker by placing bolts loosely through it while keeping it lined up to the earlier made marks. First use hand tools to install the striker bolts before checking the door closure while making needed adjustments to the striker position. When the striker shows correct alignment you should apply torque of 25 Nm (18 lb ft) to the bolts. Fastener guidelines should be used with care to prevent harm to the vehicle.

First remove the lower striker bolt from the front door before loosening the upper striker bolt enough to rotate the striker along with the spacer away from the lower bolt hole. Install the lower striker bolt before tightening it enough to maintain the position of the striker backing plate. The next step requires you to detach both the upper striker bolt and the spacer when equipped and the striker. You should start installation with the striker and spacer when equipped before installing the upper striker bolt . Rotate the lower striker bolt before removing it while checking for proper alignment between the upper threaded hole of the plate and of the bolt. Align the lower threaded hole on the striker backing plate by rotating both the striker together with any installed spacer. Screw the striker bolts tightly to 24 Nm (18 lb ft).

Hand tighten the bolts and inspect the door closing, adjusting the striker as necessary.

Remove the upper striker bolt, the spacer if equipped, and the striker.

Remove the bolts and the striker itself, followed by the striker plastic trim.

Remove the body lock pillar lower trim and the lower center pillar trim.

Align the new striker with the marked position and install the screws, tightening them to 20 N.m (15 lb ft).

First, position the door upper striker and then install the spacer if it is equipped.

Install the screws to the striker and tighten them to 20 Nm (15 lb ft).

Detach the door upper striker.

First install the striker, followed by the spacer if equipped, and then the upper striker bolt.

Tighten the striker bolts to 25 N.m (18 lb ft).

Exercise caution regarding fasteners to avoid vehicle damage.

Loosen the upper striker bolt enough to rotate the striker and the spacer, if equipped, away from the lower bolt hole.

Be cautious not to remove both door striker bolts simultaneously, as this may cause the striker backing plate to fall into the body, resulting in additional repair time.

Secure the door lower striker bolt.

Tighten the upper striker bolts to 24 Nm (18 lb ft).
