Well im finnaly redoing the front end totaly in my 86 K3500, which hasn't had anything major done to it sence it was new. It needs or I am just replacing the front springs, steering gear box, brake rotors and calipers, wheel berings, all new seals, upper and lower king pins and bearings, axle u joints. and some paint. Sorry didn't think to take pics and put on here until i already had it pretty much ripped all apart, but I will get more once I start getting the parts I have out for cleaning and putting stuff back together.

Just out of curiosity, did you experience any "death wobble" with all those worn parts? Be sure and replace the King pin bushings and springs.

Even though the springs "look fine," replace them. The pre-load on the springs has alot to do with controling death wobble. I have the axles out of an '85 CUCV under my slightly modified ;) '90 Jimmy and didn't experience the dreaded "death wobble" until started running 38's. After a lot of experimenting, I tried a trick I learned on ColoradoK5.com, I put in a couple of fender washers on top of the kin pin springs and it solved my death wobble problems. I assumed that if this solved the problem, the springs were worn and compressed. When compared to new springs, the old ones were almost 3/8" shorter than the new ones.

Check the knuckles for cracks around the king pins area. Have seen them crack under hard abuse "4 wheeling".
