How do they look? Are they welds decent?
welds look great, cant properly see the tube diameter but they do weigh in as tho there is real metal in them.
Never forget, you can get quality or crap from both China and the USA.
My take on these is that they are decent part but coupled with a lower grade ball joint. If the ball joint fails tho, they are patterned as a generic GMC part, so finding a quality replacement should be easy.

Now as I am installing them I am running into issues, it seems like the bushing diameter is greater than the body mount pocket will allow.
I was able to chamber the edge of the bushings to allow them to get in far enough, but then when I got the bolt thru, the grease fitting hits the top of the pocket and wont allow full swing of the UCA.

I wonder, was the bushing mount 'pocket' changed in later years of the KJ? Maybe made larger?

2003 here.

off to find lower profile grease fittings...

Black lighted?

I don't see any reason to go this route. The issue at the moment are simply that they used too large of bushing. Thus just barely hits the rounded inside rear of the 'pocket' and causes the zerk to be too close to the top of the 'pocket'

Right now I am contemplating drilling and tapping the zerk to the bottom of the bushing housing, then just block off the existing hole...

We always called it magnafluxed. I'm tracking.
Same process but uses a florescent magnetic particle and UV lamp, inspectors tell me its better... but they would! lol

So final report, Don't go with Deeke anymore, seems they "upgraded" the bushings to larger units that don't fit the KJ, specifically our 2003 and I don't know if the UCA bushing pocket may be larger in later years.
ALSO - don't go with the AC-Delco UCA as they put the zerk on the inside and you cant access it due to proximity of the spring.
Second note on AC-Delco - the rubber boot is very thin and very easily torn.
Took the Delco units back and got Moog UCA, Zerk on the outside, well made, good rubber boot, easy install.

Thanks for the update …time to go with UCAs properly designed and built by JBA…at least for me next time…but think I knew that already

During the pandemic I needed to replace the UCAs and LCAs and various other front suspension parts but business was down a lot so I deeply researched and agonized and then bought what I was hoping were inexpensive but decent quality suspension parts from 1a auto.

1A Auto does alot of good advertising and makes alot of good claims about the quality of their parts…and of course they offered a lifetime warranty also.

Since I decided that couldn’t really afford the JBAs at the time (hindsight shoulda just put them on a CC) I ordered the 1a parts against my better judgement.

Then just last year, after putting new Michelin rubber on Giddyup, I took her in for an alignment at my excellent and local shop ….sure enough they couldn’t do the alignment cuz the lower ball joints were already bad with less then 25k road miles on them (though granted that the roads where I live could almost be considered off road)

For me doing a time consuming twice in just a few years means that I’d MUCH rather spend the extra dime on known quality psrts instead of experimenting with the unknown and having to do the job over again….I’m not even gonna make use of the lifetime warranty cuz there’s no way I’d make the same mistake by installing the same shoddy parts yet again,

Anyways, that’s my story and I’m stickin’ to it. :oops:

In fairness, JBA makes upper arms. Not lowers....

True …that’s fair.

But it’s also fair to point out that both LCA and UCA used same (low) quality materials and likely factory as ALl the suspension components came in a kit and IIRC the whole 10 piece kit kit cost less then the JBA uppers by themselves.

Yup. Buy once, cry once. Also, MUCH stronger ball joint, and much easier to replace the joint.

Standby for the PN of the joint needed for JBA arms....

EDIT - Moog K-6292.. https://www.moog-suspension-parts.c...dsZ1q-Yevfv7cy6AuoKTSD2H_Yhl-Ec8doB2vnAkACADn

this was my plan, since with the UCA designed the way Deeke and JBA do it takes this easy to get upper ball, I was not worried if it failed in a short ish time. I did not expect the bushing size to be so much larger than JBA (assumed) that it would not fit due to diameter....

Honestly, I can't find much to argue with about the LCAa up front. Comparing them to my 97 Tacoma... Well, let's just say the mighty Toyota IFS LCAs are HIGHLY OVERRATED in that particular case. I watched my neighbor have a ball joint failure in the driver's front LCABJ (before he sold the truck to me) backing out of his driveway, and he's one to maintain his vehicles very well.

True, the KJ doesn't do long travel, but that's a function of geometry - to get that with the wheels fitting the platform, your cradle would have to be about half the width it is.

I'd be less worried about the bushings and ball joint in the Deekes brand, and more about the materials used, and the weldments made.
Quality tubing is expensive. A skilled welder willing to cut his rate making the items is about the only place you can save money on the manufacturing.... And a bad weld or sub-par tube can easily kill you.

Buy once, cry once. This is literally a life-safety issue. Would you buy a budget tier life preserver? How about a helmet? How about budget-tier heart surgery?

I am not worried of that in this case.
The UCA does not take the main stress of load, its the upper most component, not spring loaded. Yes it takes load on turns, a fraction of the stress of the lower arm.
The part had good welds and good weight indicating a reasonable tube was used. I am certain it was more than adequate.
I might worry more if it was made in the USA tho.
