I'm at a loss on how to adjust this thing. it didn't seem to want to spin by putting the metal eccentric in a vise and trying to spin the arm / bushing around it. I was trying to get the arm as close to what I felt would be right on the bench (slightly shorter than the stock arm - I'm lowered 1.5"), but I couldn't get any adjustment out of it. so I just went ahead and installed it, but even after locking the nut on the longer bolt and trying to turn it (and only finger tight on the shorter bolt), it didn't feel right. I couldn't feel the eccentric turning.

anyways, with my crude home depot angle gauge, taking 3 measurements got me an average of 1.5 degrees of pinion angle, so I think I'm good ... I hope.

I'm planning on getting adjustable rear LCA's because now the axle is tweaked slightly, showing -4 mm and +2 mm rear toe. maybe pinion angle will be more easily adjusted once the lowers are installed?

 

what is the part number for the UCA you have? Do you happen to have a picture of it? If you have an adjustable UCA you shouldn't need adj LCA's

 

You can adjust the angle while the UCA is on the car. You have to loosen the lock nut on the bolt that sticks out and that allows you to crank on the bolt which spins the inside of the UCA, take your measurement and then tighten the lock nut, maybe put some lock tight on it for good measure.

 

I thought the Whiteline UCA was a fixed unit and their LCA's were adjustable? Do they have a new one?

it has an eccentric ... which they call a "crush tube". not sure if this implies that once you tighten it, it shouldn't be loosened? and if it does get loosened it needs to be replaced?

at any rate, I think I should get adjustable rear LCA's to get the toe even on both sides. any thrust angle much higher than 0 bothers me ...

 

yep that is non adjustable UCA

 

It's adjustable....reading is fundamental

You loosen the jam nut, you crank on the bolt once it is loose and the inside of the UCA spins, similar to a cam. This will not lengthen or shorten the arm but it changes the position of the arm in the mount, therefore pitching the pumpkin.

 

I have one about to put on and was scratching my head on how to adjust it.

 

its strange because one would think an eccentric would be part of a component that is designed to be adjusted. I feel like it should have moved, if maybe with some resistance. but clamping the eccentric in a vice and attempting to spin the arm yielded no movement - at least not with the amount of force that I was comfortable with giving it. same thing as when it was mounted in the car, I tried to spin the bolt, but it just felt like it didn't want to move. again, I only gave it enough force that I was comfortable giving. it just didn't feel right. maybe I will contact whiteline about this.

anyways, adjustable LCA's are on order

 

4 shore thanks for the help
