knocking when steering

[kevin.s]

just put some 35mm drop springs on my 172 and now it seems to knock when i steer it from side to side when driveing slowly. also in the engine bay where the top of the struts are i knoticed that these turn when i turn the wheel. is this suposed to happen or are they over tightend which in effect is causing the steering to knock. it sounds like the knocking s coming from the centre of the engine bay so i thought it may be the steering rack but it wasnt doing it before and ive not herd of this happening to any one else.
please help ta

The top mounts moving with the steering is perfectly normal. Were the top mount bearings replaced?? Are the springs correctly seated. If its coming from the centre check the steering rack mounts arnt loose (lots of movement in the rack with the steering).
