I just cant imagine not having a bolt there. You better have a solid first hanger bearing in place or you will have have all kind of wobble not to mention a distorted spline shaft.

We're on the same page Peter, it won't be going back on without a bolt!

Got my box of window seals today, appreciate you selling them to me. I don't have to hunt for what I need now (hallelujah). I can now start on the windows if the weather cooperates. Already changed out the little rusty screws with stainless, glad of that what a nightmare.

Glad it arrived safe, best of luck!
You'll still need some vertical lip seal, but that'll get you started. If you've gotten the screws replaced without breaking any you're already well on your way!

Rob, for your own peace of mind, I would closely inspect the shaft and yoke splines. To get a properly fitting yoke on the shaft, you often have to use blunt force, like a 2x4 or a Rubber mallet. I once spent an hour counting splines, because it seemed they were not lining up properly. (There are 32 btw )

Also, while I'm down there, what should be looked for to see if the leaf springs and other suspension components are still any good? I haven't seen much about the rest of the rear suspension failing.

Thanks Peter, you're bailing me out repeatedly here!


Looks like the original springs had 10 leaves (or is that 9/1)

What I'm seeing for replacement is
https://www.sdtrucksprings.com/index.php?main_page=product_info&products_id=7394
Or.
https://www.sdtrucksprings.com/index.php?main_page=product_info&products_id=7395

That's regular 3760lbs or heavy duty 4500

Given that ours are cut in half and we have the airbags, and it's an extra leaf over what the 310 had, it looks like the regular makes more sense to me

I just know too well how it goes. If it wasn't for Brad and Chris, I would have thrown in the towel a few times in the past (well, at least for an hour or so)

Chris (cmadmaxman) would probably be a better source for info on the leaf springs. I have fortunately never messed with them

I'll send him a PM and see if he responds. I was hoping to leave mine, but when they bow down instead of up... I figure ignoring it is asking for trouble. If I replace them at least the entire suspension will be new, front and rear.

Chris said he ordered the 4500lb units, and they were too thick, he had to remove a couple leafs.

He recommended checking the pack height measurement, which makes perfect sense but hadn't crossed my mind, I'll take that measurement this evening

Rob, on my old 310 the leaf springs were cut off and the suspension action occurs with the air bags. I might be missing something but that means the remains of the leaf springs are nothing more than a pivot point for the suspension system.

Would it matter if the springs bow one way or the other?

What am I missing?!

Brad,

I'll need to look at it again and think it through, not a mechanical engineer, but I thought it looked like you still get some spring action, since the axle is constrained against rotating when it goes up and down, if I'm picturing it right in my head, which I may not be
