JBA Offroad Upper Control Arms And Suspension MEGA Thread BS thread

I have 285/70/17s (32.7" dia). Will I need a spacer with the JBA UCAs? Currently I only rub on RARE occasions.

 

Here ya go right off the JBA Site. If you looked at the arms on the site all this info is right there.

@Unchained 5150 word.. Sounds like I need some back space. 12mm offset spacer it is?

 

No idea I myself would never run wheels spacers. I have OEM Wheels with 255/75/17's on them and have never rubbed.

 

@Unchained 5150 I don't want to run them either... I might just run my wheels and say f*uck it.

 

Or go to Skinny 33's

 

So I have taken my suspension apart a few times and want get replacement nuts for the ball joint. Does anyone happen to know what size the nut is? Is there a better option than nylon lock?

 

9/11 NEVERFORGET

 

So I did a cursory inspection my UCAs that I installed a couple of weeks ago. One thing I noticed is that I appear to have bushings doing something funky on both arms. I haven't heard or felt anything funny so I'm not too worried about it, yet. Has anyone else seen this happen to theirs? On the passenger arm it's the front bushing, on the driver arm it's the rear.

 

Could be over greased, but I’m not sure.

 

Did you loosen the main bolt before greasing?

 

I did not. I'll have to check if that was in the instructions. Maybe that is common knowledge, I'll keep that in mind for future.

Anyone know what can be done to reseat the bushing? If it's due to overgreasing maybe I can pull the zerk to release the excess. I really hope I can fix this without taking the bolt back out.. PITA.

 

I know that’s how it is for total chaos uca’s I would assume it would apply to all though.

 

I’ve had my Icon’s swell up from over greasing but not contort. Jack up the front end, loosen the through bolt and some grease should start coming out the bushings. Then what I had to do was remove all the zerks then tighten the through bolt to squeeze the excess grease out. After doing this, the bushings should look normal, if not, I’m afraid you’ll have to disassemble it to get it to seat properly. I luckily never had to do that last part. I’d admit mine are a little under greased to avoid the swelling which in return does squeak.

 

Just ordered my JBA's today to go with my Kings I ordered.. Everyone still loving these UCA's? <--- Super excited over here!

 

Damn now I see this.. I just ordered my JBA's tonight..

 

We can trade new for new of you like

 

I'

ll keep you in mind

 

Yes. That is correct. These UCA's are not adjustable like the LR UCA's are. They go in one way (as all UCA's) & there is no alignment adjustment at the ball joint itself. The "high caster" is built in to the design of the JBA UCA's. The alignment is only adjusted by turning the LCA cams.

 

I may purchase these JBA UCA’s if I get larger tires since they will move the tire “forward” in the wheel well. As for now with 265/70r17’s the truck drives great.
