What he said. If your suspension dosent fit together right, it means you prob. did something wrong too, I'd double check its all in spec.did you tighten up the strut top bolt? Use spring compressors? You shouldnt have any trouble connecting the knuckle to the upper a arm.
Also try putting the car on athe jackstand and using a jack to raise teh knuckle up to the control arm.
