M35a2 tandem axle stuck!

[sbredhold1]

So I know the rear axle's are designed to "walk" however my middle axle will not center/allign back up. I have tried the drive straight trick and multiple forceful methods but none seem to get it back in allign. The driver side is stuck like I am making a left hand turn with that wheel being closer to the rear most wheel and the passenger side is closer to my fuel tank, spread with the most distance between tye rearost wheel. Any help or advice would be greatly appreciated!

What do your dog bones look like?

 

[sbredhold1]

It seems all the bushing are the and in decent shape. Not new of course but there.

Measure the gaps at the spring brackets, That will give an idea what is going on. Check T.M.9-2320-211-20-3-2. para. 16-12 (frame 2) thro to frame 7. the adjustent and or servicing of the bearings and tightning of same. Keep us informed.

Start at chapter 16 and read through.

 

[sbredhold1]

New here, could someone please instruct me where or how to view said "T.M.'s"
Thanks

 

[sbredhold1]

Found them. Sorry for the unnecessary post

 

[sbredhold1]

Seems it was chapter 17, however thanks for the general direction. Will dig into it this weekend and let everyone know the outcome

I have been reading up on this but never thought to look in the 5 ton TM'S, seems to be much more info here than in the 2 1/2 ton TM'S. I take it that they are almost an identical set up?

Same general set up but bigger. I believe the dogbones are a bit longer on 5 tons cause 53in tires fit 5ts but not deuces. So I dont think the measurements from 5t TM will help, could be wrong but it sounds like something is obviously tweeked. Look to see how much leaf spring is sitting on the axle perches the springs should be flush with the ends
Took a few pics of my 5 ton dont have a duese Yet

I would check the dog bones first and then look for anything else that is loose. Is everything tight and proper under there?

You should also check your Trunnion if you haven't already. If you search here you will find a good thread on it. Pull those stamped sheet metal caps in pic 2 and see if the bearings or bushings are damaged.

If you search here, JATONKA. and others you will find a load of TMs. Download them to a safe place and get them organized. You will need them.

Hi Valance.
Sorry for the confusion but it is sbredhold1 that has the problem with his truck and not me,
I was just commenting on another members quote about this problem, I am always reading the TM's about these trucks, to improve my knowledge,
This site and its members are a mine full off information for anyone who owns one of these vehicles.Many thanks

 

[sbredhold1]

So I'm at the truck and checking all the helpful ideas out. I have found that 5 out of 6 of the "dog bones" are right around 22 inches from bolt center to bolt center. Well... the side that is closer together (drivers side) has one lower bone on the middle axle that is completely different in apperance and measures 20 3/4 from bolt center to bolt center. Is this correct or do I need to be looking for a replacement dog bone?

 

[gringeltaube]

That is not correct! All 6 need to be exactly the same length, 22 inches C-C.

I wonder where that odd one came from and how it even ended there...?

[sbredhold1]

I didn't think so! Now the question is how hard it is gonna be to find a replacement

 

[gringeltaube]

Best to post a want-ad in our classifieds. They are everywhere and cheap, ever since people are bobbing their trucks.

I went out and measured my truck even though I thought it would be a waste of time. To start with, the lower dog bones and brackets are the same or mirror images if you look at it from the other angle. All of the lowers would have to be exactly the same length or something would be crooked. The same is true with the uppers as they are colinear with the center of the axle housing.

I measured them anyway, all 22 inches on the money and appear the same.

I'm curious to see a pic of the odd dog bone. If you want to be super thorough, look at the TM's with the NSN\PN of each dog bone; bet they are the same. The suggestion to find someone local that does bobbers is a solid one. If you go to NAPA they have the correct size rod end separator for about $50. I found it to be invaluable for getting those things apart.

 

[sbredhold1]

I believe i have located a replacement torque bar here locally, once i get it i will upload a picture of the current short rod
