FRONT END RECALL UPDATE WITH “BULLITT PROOF” BALL JOINTS
PART #109271
While the DeLorean was subjected to very few recalls by comparison during it's short production run, one stands out as extremely crucial. The factory devised front end recall kit was extremely necessary, although just a band-aid measure for rushed production and engineering shortcomings.
The solution was to add reinforcement brackets to the front crumple zone sway bar mounting area to aid with structural stresses under load. This portion while not the perfect solution does provide the added safety required. The next step unfortunately created more issues through improper implementation and factory inconsistencies in front spindle taper depth during the manufacturing process. The final step of the recall was to drill and pin the lower/upper joints at the threads for a castle nut and pin configuration. This exponentially reduces the load capabilities of the upper joint that in most cases already suffers from a shallow seat condition on the tapper. The end result over continued use results in excessive wear at the base contact point of the taper. As use continues the hardened shaft on the upper joint wears the softer cast material in the spindle bore creating a false loose condition.
Coupled with the now weakened shaft due to the pinhole installation during the recall procedure, this becomes a high probability point of shear failure on the joint shaft.
