that's two different arms. what are the chances that both are bent?That arm is bent.
i don't think they do, and they wouldn't if the problem solver bushings are used or caster is built into them.Looks to me that if on one side the bushings align, and on the other side, they don't, one of the two wasn't made to specs. Do factory ones align? Since they don't use one common through bolt, I frankly never checked in the past.

The reason the bushings don’t align is the tubes are turned and welded to the ball joint end crooked and that makes the geometry of this arm different than the other. I know it bolts on to the car with two bolts, but their other arm is flat and the bushings align perfectly, so if that’s not right then what is wrong. In the current form, there is no amount of creativity that is in this, just incorrectly welded together. I don’t even have to try fitting it to the car because it’s a waste of time an effort since I know it won’t fit and align the car. The car is drivable with factory arms on it right now, just not much castor, so I am not disrupting that when I know something is not going to work. I have been working on cars and equipment my entire life and consulted several local friends that have rebuilt several Mopars over the years, and we all agreed that this arm is not usable.
The dismissive attitudes I got on the phone from all of them got me upset. They start sentences with “I’m not arguing, but that came off a jig so it’s fine.” I don’t dispute it came off a jig, but somethings wrong with the jig if it did. And they have all these excuses why they couldn’t just replace the defective part in less than 2-3 months… not to mention flat out calling me ignorant.
Why don't you out the f'ing company so others here and other places don't have the same f'ing problem???????????????

Pretty good, especially if they came off the same car. It could also be wasted bushings causing that issue, but the holes should be aligned. That doesn't mean that an acceptable alignment couldn't be done with those arms, either.that's two different arms. what are the chances that both are bent?
1st off I did not know what company as he wouldn't state it, And yes I did not have the time at the moment to read it and I did say (but maybe something in this post?) I thought maybe something in there related. Sorry if I pissed you off. I never claim to always be right aand I try to help when I can. If you ever ask a question I'll keep my mouth shut.So you didn't bother to read it, and you posted a link to a UCA failure of a UCA made by a COMPLETELY DIFFERENT COMPANY.
That’s easy hit up @BergmanAutoCraft He is an active member here.I really hope and pray you get to the bottom of this I need a set of tubular upper a arms and I do not want to invest in the wrong ones....hint hint
Just my two cents. Has the car been in an accident, if so the frame or ears may be bent. I'm referring to the used arm in the photo. I agree, the ends should line up, or the bushings will fail shorty. Like any business, you are only as good as your help. In this case, your supplier. Time to wake up or you will no longer have a business. Keep your customers happy. My take here for a positive solution is, the company that sold the defected part should contact the supplier and see if they can find another upper control arm from another company that they sold to and send the customer another one, DONE DEAL.Pretty good, especially if they came off the same car.

Post 20 shows that even in factory UCA's, the bushing holes don't always perfectly align. They probably don't have to since the rubber can accommodate slight misalignment of bushing axes. I agree is is best that the holes align, so the brackets on the frame don't see a bending force as the UCA moves up and down. The manufacturer must surely align the bushing sleeves on a welding jig since I can't imagine how else they would set it up for welding. Perhaps the misalignment comes from how the bushing is pressed in and/or its concentricity. OP could hold a straight edge against the sleeves to see if welded concentrically. Regardless, they will likely work fine on the car.
Thanks for post 26 since I had considered those fancy UCA's with easy caster adjustment. Re what happens when a control arm fails, I investigated that 10 yrs ago after posting a temp fix on my 1984 M-B to drive it home which resulted in flames from web forum "experts". Usually, control arms (and ball joints) fail at low speed when turning sharp, such as parking lots, since when they see the highest loads. The wheel usually splays outward, but you can still steer and brake. The front may drop if that control arm supports the spring (LCA in our Mopars). Early 2000's M-B LCA often fail by rusting thru from the insides, with no signs until they snap. Those were formed from rolled flat steel, while my 1984 has solid forged LCA's. Worst failures I've seen on the web are in Tesla Model S/X until ~2017 when they redesigned the aluminum suspension parts. China forced a recall, but Tesla balked for U.S., claiming "specific to Chinese drivers or Chinese roads", though they commonly break elsewhere and often the "whompy wheel" damages body panels or even loss of control (current death lawsuits).
