Noise in front end when steering wheel is turned

Try replacing the Sway bar bushings first, 10 to 1 they need it anyway, this should fix the creaking noise. If this dose not solve the problem then check the power stearing fluid & top off if needed, then right after you do this, start the van and have some one you trust turn the stearing wheel hard left and hard right for 2 min., and you get under the front of the van and look for a power steering fluid leak, if you find a leak replace leaking line or part. If this dose not solve the problem in some rare cases the power stearing box or pitmen arm is bad and you should not try to do this at home. seek a full auto shop.

Is your van 4WD, AWD, or rear wheel drive? if it is 4WD or AWD, the front axle seals might be going bad. PLEASE RATE MY ANSWER.
