I've just bought a pair of reconditioned steering knuckles from Ebay, but I'm finding them very stiff to turn. I've put them in a vice and tried to turn them back and forth but it takes all my strength to move them from lock to lock. Pumping grease through them makes no difference either. Now that I've fitted them to the car the steering is very heavy to turn. (Worst nearest far left and far right though).
Would you expect reconditioned units to need to do some mileage before they 'loosen up'?
Or should I send them back?
Your thoughts please.
