Successfully replaced both front lower control arms (LCAs) on our 2005 SE in latter March 2016 (approx 145,000 miles). No problems with the install...until 3 months later when the original LCA Pivot Bolt (part # 54368-CA00A) broke.
I had ordered new LCA pivot bolts and LCA frame bolts from my local Nissan dealer however they didn't arrive in time and so we had used the original bolts for the replacement installation.
The fact that 3 months later we had a steering/alignment problem and found the broken pivot bolt gives rise to the following question:
What is the correct method for tightening LCA bolts?
Answer 1: OK to simply tighten with the front suspension hanging in the air;
Answer 2: Must have wheels on the ground or at least wheel on an elevated ramp or rack so that the pressure is neutral on the LCA attachment points while tightening the bolts to the torque spec. The reason given for this method is that, at "wheels on the ground" position, the LCAs are at minimal pressure or torque, and thus the bolts (especially the pivot bolt) will not prematurely wear out.
Several mechanics, including a local Nissan master tech, says that Answer 1 is they way it's always done. However, I see in the Nissan manual a reference to "wheels on the ground" as the preferred method for LCA bolt tightening.
Please weigh in on this question and your experiences.
Thank you.
