just measure the rear to see if it is out of line. if so then you see by how much then adjsut the panhard rod accordingly then fit it. after fitment let it settle in then re-measure everything again and make any fine adjustments if need be.
I got one quick question here. When u adjust the panhard rod, did u adjust it with the wheels on the ground or above the ground? Only saying this as measurement can only be taken while the wheels are on the ground, but how do we get underneath to adjust the panhard rod? Cheers.
the aftermarket one is stronger/thicker therefore keeping it more stable/less flex......
