I assume not, but just making sure. I just got done putting in my MM Caster/Camber Plates and don't feel like doing my control arms tonight. My alignment is scheduled for noon tomorrow, so will I need another alignment after I put my control arms either Sunday or next weekend? The only adjustment in my rear is the adjustable panhard bar which adjusts how the rear tires are centered in the rear. Other than that, my adjustable upper control arm I'm putting on can be hand
adjusted by me and has no effect on the suspension I'd think. The billet lower control arms and relocation brackets (I'm using the bottom hole on the BMR brackets) also wouldn't really affect anything I assume.
anytime
you change any suspension component, you should have it atleast checked, if your doing the control arms i would def have it redone.
I would assume your referring to only rear LCA's. That being said, if the LCA's are adjustable, then you need to at least confirm the driveshaft angel as specially since your adding an UCA. You'll also want to make sure that both LCA's are measuring the exact same length when adjusted properly and that your wheel center is the same and within spec on both sides. The panhard adjustment you can do yourself, its not that
difficult and can be done with the plumb level method by hanging a string from the fender lip to the ground, with a heavy object tied to the ground side. Then measure from the center of the rim to the string and make sure its even on both sides. If your doing front control arms as well, then absolutely, you need an alignment after installing them.
If you are talking about front lower control arms .. YES. You will want to align afterwards FOR SURE. Rear stuff... not so much, unless it's an IRS car.

All rear stuff. Billet LCAs with relocation bracket and Adj. UCA.

So the correct answer from FORD is NO. If you are replacing your front lower control arms, no alignment needed.

Got aligned today. Drives amazing now and all he had to tweak was the toe because I basically got the caster/camber spot on. Also he told me that I don't need to align the car after I install my LCAs and UCA.
GOOD TO KNOW!:beer: That is certainly not the case with with 2004 and earlier Mustangs.

would still do an alignment even if Ford says it's not required. When an alignment makes a change when it's 1/16 difference, any little thing can throw it off. Yes, if the arm was EXACTLY the same, you in a perfect world would not need one. But being the bushing hole could be off center, the arm is welded which means it can twist in its heating/cooling cycle and quite few other things. For as often as I see stuff wrong with parts, verifying an alignment is cheap insurance to save a few hundred
dollars in tires. Tires can still wear even if you don't notice a pull.

wide spread and very well known to those of us who work or have worked at Ford dealer for a period of time. I do know that build quality and tolerances have in fact tightened up significantly, so it is possible that there may not be much negative impact from this policy. Users who are viewing this thread
Can control arms cause alignment issues?As control arm bushings wear, this can force the vehicle out of alignment, causing wear on the outer or inner edges of the tire. While sometimes this is just an indicator that a proper alignment is needed, it can also be caused because of worn bushings. Any alignment shop will be able to properly diagnose this.
What should you do after changing control arm?If control arms are replaced, do an alignment.
Do you need a front end alignment after replacing upper control arm?Most certainly you will need to have a wheel alignment performed, including camber, caster and toe adjustments, after replacing such components.
Is it worth replacing control arms?The most common reason to replace a control arm is to improve wheel travel as part of a suspension lift. However, a new control arm can offer more than just increased ride height (lift) and additional wheel travel: Increased durability in the arm itself. A wider range of uniball/ball joint options.
