hey im installing a 40 mm body lift on my d22, done the passenger side no problems then started drivers side the back will go up easy but when i try jacking up the cab on drivers side it wont lift the body without lifting the chassis at the same. i have lossened the steering spline clamp so there is give there and taken cowling off rad fan. but wont jack without lifting chassis. whatever is holding it it feels solid too. any ideas?
