New Suspension settling
« on: April 02, 2013 - 03:47:15 PM »
I notice that the Cuda is leaning to left about 1 ½ lower than right. I just finished the car a couple of months ago I have about 700 miles on the vehicle since the completion. The suspension has been completely gone through. New ball joints, bushings, tie rods, hemi torsion bars, new rear springs, shocks front and rear. I am assuming that the suspension has settled in, and has caused the lean. The car seems to ride much better the more I drive too.

So my question(s) is; do I raise the left or lower the right. What are factors considered in ride height?  Should the top of tire be level with the top of the fender opening slightly below or above things like this.  Tire size 275/60r15 on the back and 215/65r15 on the front

A lot to do with personal preference. I like as low as possible. I've seen 'cuda's with the front cranked up REALLY high. Kind of a gasser look. If you like cornering, you would want to lower the right side, as long as it doesn't rub.  :2cents:

 Dumb question but are we talking front or rear here ?
 Generally if the rear is sitting low on one side [say left rear] it is the opposite T bar causing the problem so you would lower the opposite T bar [front right] as the rear springs are a much lower spring rate than the front .

Actually it looks as if the entire left side front and rear, but it is most noticeable from the rear though I can post some pic’s tomorrow when I get off work

it's all a matter of personal preference.  I prefer a slight rake.  I hate a$$-down Challengers.   :nono:

Just start cranking on those torsion bars to get it all level.

sorry to break in on this topic, but what would cause left front and right rear to sit higher than right front and left rear?
The car has not been aligned yet, and caster/camber is not correct...

I think I would start with asking you how you are measuring height. IE, control arm/frame points or fender lips?

Start adjusting the Torsion bars , make Sure you lift the front end when you do this though in case an adjuster strips . I am not sure which way you want to go up or down but level the front first then make mior adjustments to the front T bars to tweak the rear ride height . for example 1/2 turn of the adjust m,ay not affect the front height by as much as 1/8 " but may change the rear height .

The caster/camber/toe-in should be at least CLOSE to correct before trying to level the car.

Ok here is some more information,

1) it has had a wheel alignment, from a very reputable shop
2) measurements are from the wheel lip through the center of the wheels

FL 25 1/4  FR 25 1/2  difference 1/4
RL 26 3/4  RR 27 1/2 difference  3/4

3) drives straight  no pulling in either direction

Questions:
1. is this a common issue with newly assembled suspensions ?
2. which torsion bar should I adjusted and how many turns should I start with?
    (not sure if I want to lower the right side  or raise the left side)

Ya, lower the front right.

It's common for suspension to settle after installation.

Yep make sure you have the wheels off the ground first. Then bounce the front end and take the car for a ride  to make sure it's settled
