I have identified two reasons for my inability to align the shock absorber and knuckle: firstly, I installed the spring incorrectly, with the flatter end positioned against the top mount, a distinction that is challenging to discern; secondly, and more significantly, the CV joint had dislodged.
This occurred when I applied pressure to the wishbone/knuckle to remove the shock absorber. The hub/disk remained stationary, indicating it was still engaged, although it had retracted sufficiently to prevent the alignment of the two components. Ultimately, I enlisted the assistance of a retired mechanic, marking the first occasion in 40 years of automotive repair that I sought external help.
I was astonished by the considerable effort he exerted to properly reengage the CV joint into the coupling by the differential. It took him approximately 10 minutes, and it protruded by about 2 to 3 inches.
Subsequently, he loosened the drive shaft bolt securing it to the hub using a substantial impact driver. This was intended to enable the hub to be depressed sufficiently to connect the knuckle with the shock absorber, allowing the hub to slide on the driveshaft splines rather than dislodging it from the CV joint once more.
Subsequent to all that, it was effortless to insert the shock into the knuckle. I decided to document this in case someone else has the same difficulty in the future. I have utilised computers and the internet since the 1990s and previously worked in IT; yet, I have been unable to locate anyone online experiencing the same difficulty.
