What I plan on doing is this: Get the bottle jack from the LMTV jack up the body high enough and secure with a large jack stand. Get two c clamps put them on the springs. Losen the U-clamp bolts. Take off the sway bar at the frame. Take off the drive side wheel. Use another jack to support...

What if i start by checking the spring locating pin first? If it is sheered the i know that i have an issue right there. Do i have to clamp the springs or can i take the u bolts off with weight on the axle and peak under the top bracket?

So I took a few photo's maybe they will illustrate the situation a bit better. this photo above is the passenger side This picture above is the driver side. I measured from the passenger rear tire lip at 14" above the ground and got 100 1/2" between rear tire and the edge of the front wheel...

Speaking of 809 , where can i find definete information about the model years. I just saw a 1988 (whaaaaa???) M813A1. someone said something about models being still produced after the model ended. I can see that happening for a year maybe . But 6 years?

Steering wheel is off and then some I took inspiration in sneekyeyes thead and since i have a similar issue i want to start my own to not get replies confused or jumbled up. My left axle is back toward the fender by about an inch and a half. My steering wheel is off center. The truck drives...

Oh yeah i remember seeing brakes like that on mud trucks. I think they do that as the wheel brakes usually are wet and full of dirt. That sounds like a great option. I gotta google that.

I noticed that one side of the axle in my truck seens to be slid back slightly . Maybe a 18 inch and my steering wheel is not straight center, either. Could the axle shift be the reason? And how do i fix it?

Probably in the same location this person has his installed . If it is installed before the fuel filter, it will prevent the filter to lose its prime. If installed after the fuel filter it will prevent reverse flow from there forward to the engine. it could be that with it you will be able to...

You may want to get a check valve to prevent reverse flow. https://m.youtube.com/watch?v=TncqnkMjEmk

I would suspect the mechanical lift pump. There is a reservoir on top of the Injection Pump and maybe you burned off the fuel that was in there by idling the engine for 20 mins. There is a short fuel line that goes into the Injection Pump, I would replace that for a clear one. Then you can...

What do you mean when you say rebuilt? I have seem some trucks that had the year 1985... or even a 1988 m813a1. Did AM General really build these trucks for that long? I thought it was 1982 when production stopped. Are you saying that 1982 trucks were taken, rebuild and then used a a 1988? thx

I'm in Easley SC . maybe i can help you. I have a M1009 , too

I posted a new thread with my question above and was told off that I shouldn't cross post, But I would still like to have an answer to my question.

I kind go hijacked my own thread with this question. So I'll post it again in a new thread. I was looking at the M809 serie and Wiki tells me that they were build until 1982 then the new 5 ton M939 came on. When I googled them I saw some as high as 1985. So I am wondering until what year has the...

Do all years of m809 have single circuit brakes ? Or are there differences in years?

First you clean all ground connections and put dielectric grease on all contact surfaces. Then you test and charge both batteries . Then you test the ignition solenoid or better replace it with a different model from napa. Then you test the ignition switch , replace if necessary. Disconnect the...

Ive seen grade 8 bolts shear off. Besides I rather have a bolt break, than the bolt rip out the threads of the starter bolt hole.

I have heard that they 'could have gotten wet overnight ' I wonder over how many decades of night, he is talking about now.

Have you ever had the brakes fail on you in your M809? Not sure but are they not single circuit brakes?
