I have a 98 3500 2wd and at 80,000 miles the second gsteering box is going out, the sector shaft has elongagated the bushing again, i want to install a 2002 box as they cost 200 more and i think they have a lower sector shaft bearing instead of the bushing. Have any of you looked into this or done it. My friend has a 02 and i do know it steers better than my 98. Thanks for any help RichardOo.
