what can cause front end sag
what can cause front end sag? my truck is f350 4x4 drw, I suspect shocks are stock I also want to say that my tires on front have abnormal wear pattern the outsides a wearing faster than the middle, my truck has only been out of alignment and driven for a total of 2 days since I've had it because of replacing tie rod components so I don't think those 50 miles caused it, but can shocks cause sag? bad front leaf springs?(none are cracked) I know there are many bushings to do with the springs but I cannot completely understand the names of each and where they are

my front tires are both 70psi, I just looked at them, I was looking at a 4x4 dually that looked exactly like mine except white but he had either a 351 or 460 his front end seemed much higher probaby because a lighter engine, kingpins are the old versions of ball joints? I'm guesssing spring bushings the only way to check them is visually

not to sound dumb but I don't understand what that means david85, I can tell you that my front axle is a dana 60 axle with manual lockouts 2 leaf springs on each side with old shocks

you have a solid front axle. Independent front suspension means that the 2 front wheels can move up and down independently of each other

The shocks do knot hold up any weight just control it and can cause rough tire wear.
The weight of the motor should not cause it to sag either, however if you have a plow much and have a lot of miles your springs could be getting weak.
The bushings and bolts and shackles will cause it to sag more than most people realise.
You should have load range E tires, so 70 would be under inflated.

Generally when the term "sag" is used in the context of these trucks it refers to a problem the independent front ends can develop over time where the front tires look like this when viewed from the front: /--o-\ That can also cause some crazy tire wear issues if not corrected - but again thats on independent axles only.
Such a conditions are impossible with a solid axle (unless you have VERY worn out ball joints or bent axle tube) which is why I wanted to make sure I understood what was happening.

thank you for your input, what is the proper psi for load e tires? and I'll check to see what the tires say about load range, it is the leaf spring bushings that are the biggest pain to change, yes? but the leaf spring shackls are easy?

also if it helps all my tires are Dean, trailcat 235/85R16
Edit: I was just looking at load range tips on googel it says load eange E is for 80psi?!?!?! I thought 70psi mightve been too much?
