Lower Control Arm And Tie Bar

WARNING: This page is about a different car, the 2020 Jaguar XE and 2019 Jaguar XE. However, it is still accessible from the selected car via links, so may be relevant.

Lower control arm

The lower control arm is cast aluminum with a bushes pressed into the inner section of the arm which provides for the attachment to the subframe. The bushes are located between brackets on the subframe and secured with bolts and nuts. The lower control arm has a platform which provides for the attachment for the coil spring and a location hole for the attachment of the stabilizer-bar link.

The outer section of the lower control arm has a second bush which attaches to the forward end of the wheel knuckle. A bush at the rearward end of the lower control arm attaches to the wheel knuckle's rear bush by an integral link which provides castor control.

Tie arm

The tie arm is manufactured from forged-aluminium with one end having a bush pressed into a machined bore.

The inner bush locates between brackets on the subframe and is secured with a special eccentric bolt, washer and nut. This allows for the adjustment of the rear wheel toe. Rotation of the bolt moves the eccentric head within a recessed slot in the bracket, allowing the toe to be adjusted within the set limits.
