Adjusting lower control arms

Slider1385 · March 14th, 2009, 09:51 PM

I bought a set of adjustable lower control arms. I set them for the length of the stock ones but I would like to check and make sure that my rear end is perfectly square. Does anyone know how to go about this, I did a search and came up with no good results. Thanks

You probably wont find the exact measurment, as bushing wear and amount of drop will come into play.

You will not be off by much and I would probably just do this by sight (you could measure wheel well gap too). I you were REALLY into pinion angle and such, you should go with adjustable UCA's as well.

I have the adjustable uppers, I know how to do those as I have an angle finder. The lowers however were the ones I'm not too sure how to measure. I just want to make sure that my rear is perfectly squared up.

simplest method would be to make sure the length is equal on both arms. But that will only give you relatively straight set up. The best way is to use a plumb bob to hang from the chassis and the end of the LCA to make sure its the same on both sides.
