TECHNICAL NOTE:
Whenever the differential unit is removed, it is important to check the condition of the
chassis frame mounting points, as these sometimes fail in service.
The R.H. front mounting point fails most often, probably as a result of the stresses placed
upon the frame by engine torque. The first indication of this problem is a `'clunk'' anytime the
car is moved either forward or backward from the stopped position, just as the clutch is
engaged. A simple test for this problem is to slowly move the car backward and forward
under power. In pronounced cases, you will hear a `'clunk'' each time you engage the clutch.
The first manifestation of this problem is a crack across the bracket which supports the R.H.
front differential mounting bolt, and at this point the problem is easily resolved by simply
welding the crack. To permanently solve this problem, even if the car is subjected to hard
use, you can reinforce or replace the bracket and even `'box'' it in per the illustration in this
section. Any good welding shop can complete these repairs at a reasonable cost.
If the problem of a cracked mounting is not attended to at the early `'clunk'' stage, then
additional stress will be placed upon the chassis frame at the point where the upper end of
the bolt is welded to the rear suspension crossmember. Sooner rather than later, stress
cracks will appear at this point, adding to the expense of the repair and increasing the risk
of additional problems and failure on the road.
