{Chrysler 300} Front Suspension Lower Control Arm Procedure.

["'James Douglas' via Chrysler 300 Club International" <chrysler-300-club-international@xxxxxxxxxxxxxxxx>]

Hi all,

 

There is an inconsistency in the 1964 Service Technical Manual on pages 2-8 and 2-9.

 

On the installation of the lower control arm it states on item #1, “…DO NOT TIGHTEN the front nut until the full weight of the vehicle is on the wheels.” Then on item #10 it states, “…Tighten the lower control arm shaft, (the ¾ inch) nut to 180 foot pounds…”.  Then on item #11 it says to, “…Lower the vehicle to the floor…”

 

So, can someone tell which is it? Tighten it with weight on the car or before you lower it?  I suspect it is to be done after the car is on the floor and item #10 and #11 is just an error carried over from some older text. One would want the rubber bushings on the shaft to be “neutral” with the car on its wheels. If one tightened it first then it would rotate and load the rubber on the wheels and probably actually change the spring rate and the life of the bushing.

 

Thanks, James
