Front springs

Look for your nearest "Triangle Spring" distributor.

 

Where are you at? Most any spring shop can do it. In Florida I use Tampa springs in Ocala. In Califonia I use J & R fleet service. They can handle just about anything

 

I buy them from my local independent truck parts outfit. Saved me hundreds of dollars I see they shipped from PA. If the distance between the rear spring eye and hanger, or frame, is the same on both sides, put a small jack between the spring and frame right in front of the hanger to make it so. If the truck is level you should be able to get by replacing spring pins, bushings, and rear hangers. If not level it it has a colapised spring. Replace both and the rear hangers. Not sure I explained that very well but often times the rear pin wears through bushings and into the hanger. If one side wears twice as far as the other side the truck will lean that way. A quick check is to look at the distance between the spring and the hanger.
