Hi. So I need some help with a Clayton 4 link rear. Are the upper arms for pinion/side to side and the lowers are for wheel base and thrust? Been having some vides that I've been fighting to get rid of. Thanks
Have you taken a magnetic angle gauge to the pinion and TC yokes to make sure everything is adjusted for the correct angles for your set-up?
If the angles are good, you may have an unbalanced driveshaft or damaged yoke/u-joints so you may need to take your DS to a DS shop to see if they can balance.
Point your rear diff pinion to to T/C flange then adjust down 1-2*
Front point pinion same way but you have to adjust down till you have enough Castor..min 4* as a start may need more but then screws up the DS angle. That's why some will cut and turn the "C's"
