FIX KIA Sportage QLE Mk4 Notchy Steering rack issue
Mk4 Sportage's are renowned for developing notchy steering (especially at motorway speeds) and it’s normally due to a lack of grease in the steering rack/box.
This videos shows you where the dealerships add grease for the technical bulletin.
only the smaller undertray/shield in the middle of the car needs removing (4x 10mm bolts) and then you'll need a 10mm ring spanner to remove the 3 10mm bolts on the steering rack/box cover which sits just on top of the subframe under a heat shield (it's tight but there's no need to remove the heatshield).
