I have replaced my pitman arm several time in my 03 2500hd silverado. The last time I had less than 100kms on it and took it in for a wheel alignment and they told me I needed a new one. I dont know if it is because of using aftermarket parts or if mabey the shaft on the steering box is worn out. Also when you have some one move the steering wheel and check out the linkage and steering components it appears as if there is alot of play inside the steering box it self. Is there a way to tighten up the steering box? 03 silverado 2500 hd 6.0L 3" lift

 

if you have wheels bigger than factory..or lift kits...you'll eat front end parts
