FRONT SUSPENSION PICTURE GLOSSARY. WIP
Posted: Wed, 20 Oct 2010 9:53 +0000
Here is the first of a few photo glossarys that will be added to the forum over a period of time.
For those who are not sure about the parts and components on the front suspesion of the hilux and what they do here are some basic pictures a brief description of what the part does and maybe a link or two that can take you to a more detailed thread that describes it function better. So this is clear as there are many parts to the front suspension the description of the parts will be BELOW the photo and the subheading will Be 1A and so on.
PICTURE 1
1A. Upper Control Arm. (UCA) Moves the wheel through an arc in the suspension travel. Running wider tyres can cause them to rub on the control arm so the need for different offsets in rims to prevent it may be nessicary. There are other options of fitting aftermarket UCA items if lifts exceed 2.5 inches.
Upper Control Arms
1B. Lower Control Arm. (LCA) Moves the wheel through an arc in the suspension travel similar to the UCA. Camber and Castor adjustments are done on this suspension component.
1C. Stub axle bracket. Holds the UCA and LCA together, along with the stub axle, front driveshaft and also holds the brake caliper in place. Gives a pivot point for the steering as well.
1D. Strut Assembly. Commonly refered to coil overs, struts. Comprises of a spring and a shock bolted together. Most lift kits up to 2-3 inches replace this to achieve the lift.
Common manufacturers of 2 inch lifts.
1E. Sway Bar. or often also refered to as an anti roll bar. Transfers downward movement in the suspension from the inboard side of the vehicle to upward movement to the outboard side of the vehicle to combat vehicle roll when going around a corner.
Swaybar removal
1F. Steering rack/tie rod end. Connects the stub shaft to the steering rack to allow the vehicle to turn.
1G. Front Drive shaft. (CV) Connects the front diff to the stub axle assemble to provide drive to the front wheels when in 4wd. Also allows the drive to be flexible and permit the vehicle to steer. There are plenty of threads in the drivetrain forum on this topic.
PICTURE 2.
2A. Bottom Bumpstop. Mounted on the chassis. A rubber stop that limits the upward travel of the suspension to prevent the wheel hitting the guard and also stop the strut bottoming out through compression.
2B. Bottom Bumpstop Contact point. Bottom Bumpstop hits this to limit the upward travel of the suspension. This is shown buy the distinct witness mark on the LCA
2C. Adjustment. Not normally needed to be adjusted but if strut spacers are fitted it should be extended to prevent the strut itself bottoming out.

PICTURE 3.
3A. Camber Adjustment.
3B. Castor Adjustment.
3C Upper Ball Joint.
3D. Upper Sway Bar link.
3E. Lower Sway Bar link.
3F. Tie rod end and ball joint
3G. Lower ball joint
3H. Lower strut bush.
This is an open thread as suggestions and questions may be asked about components here. I will move it into the mod section from time to time for maintenance.
