INSTRUCTIONS - Lower Control Arm Adjustment Reinforcement Kit Posted on 28 Aug 10:10
The installation of the Lower Control Arm Reinforcement Kit requires minimal mechanical knowledge and tools. It is important to follow these instructions.
- Socket Set / Spanners
- Nylon or Rubber hammer
- Begin by lifting the front of the car up either on a hoist or jack. Make sure this is done safely, eg: Use Jack stands if you are working underneath the car and lifting with a Jack.
- Carefully remove the lower shock mount bolt to take pressure off the lower control arm adjusters. If you are running standard shocks this may not be necessary.
- Loosen the locking nut on the LCA (Lower Control Arm) adjustment bolt on 1 corner. (eg: Right Hand Side Front adjustment bolt). The locking nut uses a 22mm spanner/socket, and the adjustment bolt a 24mm spanner/socket. Remove the nut and bolt completely.
- Find the appropriate reinforcement plates for the corner you are working on. The laser etched letters on the back side of the plate refer to the position they go on the car. eg: RHS FF refers to the right side of the car, front LCA mount, front adjustment guide.
- Fit the front and rear adjustment guide reinforcement plates for that corner you are working on. These plates are designed to accommodate factory production differences, and depending on the vehicle may be a tighter or looser fit over the factory guides. A few light taps with a nylon hammer or similar can help seat them properly. If your car has already bent/deformed the tabs, these will need to be carefully straightened before you can fit the reinforcement plates. If there is weld spatter preventing the plates from fitting up, this can be taken off with a die grinder or barrel sander.
- Fit the adjustment bolt back in place, being sure to grease the shank of the bolt to prevent it rusting and seizing to the lower control arm bush. Replace the rear washer that sits under the nut with a new stainless Munji washer. These are designed to be an interference fit in the channels cut into the bolt, and as such will require some light taps with a nylon hammer, whilst holding the bolt head from behind, to press them on the first time. By having a tighter fit there will be less play in the adjustment assembly, making it easier for your wheel aligner, as well as more material holding the washer to the bolt, making it much stronger and harder to strip and spin. Once the washer is installed the nut can be fitted loosely.
- Check to ensure the plates are sitting correctly against the chassis. There can be a very small (0.5-1mm) gap in certain areas of the plate, but anything more means the plate is not seated correctly. A few taps with a nylon hammer once again can help it find its happy position.
- Repeat this process for the 3 remaining corners. The rear mounts will require the crossmember to be loosened and pulled as far down as possible, when fitting, as the reinforcement plates lock in behind it. After fitting the rear plates it can be lifted back up as high as it will go and retightened.
- Once all 8 plates are installed, the car can be lowered to the ground and all 4 adjustment bolts tightened. Do this at ride height to prevent the bushes failing from premature wear. The lower shock mount bolts can be reinstalled and the car taken to get a wheel alignment. a wheel alignment MUST be done after fitting this kit.
