Swepco 715 is my favorite secret sauce. Easily obtainable from Summit Racing. Has all the vitamins and minerals your Saginaw steering and hydro boost system craves. Plus PSC and a few other outfits suggest it. I don’t think it will make or break anything, but I have had zero failures or...

The adjuster plug isn’t something you can R&R Willy nilly. If you remove it to replace the seal try to keep things squeaky clean and follow these instructions. “Adjusting thrust bearing preload”

I know this is very late to the game, but the injection pump looks like it may be leaning towards the drivers side in that photo. Just curious- does the timing mark line up between the pump and flange?

Okay - I heard back from a buddy of mine that parted out an M1008 about 8 years ago. He still has the frame leaning on his shop wall (indoors). Located in Yreka CA. I don't want to be the middle man, but I will PM you contact info.

When you re-seal it make sure you assemble it correctly and mind preload.

This is one of those deals where being patient will make it cheaper. Many a M1008's were parted out once liquidated. I'll ask around locally when I get back home from work about a frame. Regional prices on square body trucks and parts are wildly different - so shop around. Personally I think...

My money would be on injector issues. I had mine sound like that when it broke a nozzle. When it is idling crack loose one injector line at a time and see if the noise goes away.

Keith did a nice job of explaining it. The injection pumps diesel using two little opposing pistons inside the rotor, as the rotor turns the pistons are pushed in by rollers as they make contact with the cam ring. The pistons and the "leaf spring" are highlighted in the photo. Turning the...

When you start the vehicle for the first time in the morning and it is less than 10C outside does it run at a higher idle speed and sound louder? There is supposed to be a cold advance circuit that changes the timing when the coolant temp is below 40C (approx). This same circuit energizes both...

I don’t know what the timing specs are, that would be helpful to know. Is the cold advance working? Listening to it from my cell phone speaker sounds it sounds normal.

Mr Sawzall has to come out to fit 37's with a 4" lift… Unless you never deviate from a straight line, or articulate your rig and have springs out of a Peterbilt. IMHO -If you choose wheels carefully (stick with around 4.5" backspacing) you can get away with 34-35's but it will be close.

Anytime steering box adjustment comes up I figure it is a good idea to post the instructions from Saginaw.

Exact same carrier, bearings, R&P as before? If so you should be good to go. Hopefully it is a tight fit- if it slides right in you may want to take a close look at your carrier bearings.

Glad you enjoyed the video. One of my buddies has an M1008 with an ORD 4” shackle flip and no pinion angle shims. It does okay on the road. I think it does as well as it does because the pinion is angled up so high that the pinion is pointed above the transfer case. The angles at both ends...
