I ordered some JKS Adjustable LCAs for my 09 Rubi Unlimited. I was told they can be used to give your more Caster and better handling (stability). Are there any tricks to their install and adjustment I should be aware of prior to install?

As usual, thanks to the forum!

Straight forward install on the lowers. (you need to cut a bolt out to install the uppers). See the Setting your Caster section in this link for some tips on tilting the axle to help get the holes lined up.

Thanks for the great link. In that link, he only adjusts the upper control arms. Can I achieve the same poitive caster adjustments with just the lower control arms?

Thanks,

Sure can, uppers and lowers do the same thing, just opposite.


Uppers:
Shorten to raise caster
Lengthen to lower caster

Lowers:
Lengthen to raise caster
Shorten to lower caster

Both sets:
Lets you move the entire axle forward/backward in the wheel well.



Since front lowers are lengthened to raise caster, they are the better option, as the uppers may not adjust short enough to get the caster where we want it.

 

Thanks for the great responses! Love this forum. The trick, I assume, is to just do one at a time?

Yep. Unless you have stands under everything, (frame and axle on both sides) it's best to only disconnect one side at a time.

 

A ratchet strap can be very helpful for helping line up bolt holes once the arms are out if you are doing the work alone
