Rebuilt Jaguar-based Rear Suspension
|When we rebuild a Jag unit for our subframe, everything that can be
practically replaced is:
The rebuild in process, before the hub carriers and axles are installed.
Reinforced Control Arms
The lower control arms are shortened from the inner end and diagonally reinforced for extra stiffness. Because we also use trailing arms, the stress at the junction of the tube and inner forged yoke is reduced by 70% from its original Jaguar design.
In addition, the diagonal reinforcements eliminate almost all flex from the inner "wishbone", which was small to begin with.
Fail-safe Axle Design
We modify the original Jaguar axles by cutting off each yoke end after turning down the shaft a small amount. It is then press-fit into the tube and welded.
If the weld fails (which it won't), the yoke will turn inside the tube, but because of the wheel offset, the yokes will not come apart from the tube. In addition, because the axle is a press-fit, the pieces may friction-weld themselves together so that you may even have a small amount of drive torque afterward to limp home.
