Design flaws? Torque rod, split rims?

[doghead]

Unless your parts are new and went bad, how can you call it a flaw?

Are you a suspension design engineer as well as a truck driver?

Sorry guys my lack of proper teminology. 2 piece rim. It's not leaking at the tube going into the rim, when I spray it into the hole around the tube I start getting bubbles. The seal between the two piece rim has a very slow leak. Takes two or three days to deflate.

Have you replaced the 20 year old tires the military had on it or the 20 year old o-ring between the rim halfs rubber dry rots over time ?

As for OTR trucks have you driven one with wore out bushings in the walking beams they will travel far enough to rub the tires on the frame and if bad enough cause tire blow-outs.

so does the older MV suspension, the springs and pocket take care of the side to side movement, and the torque rods take care of the roll and front to back movement , you loose a torque rod (strut) on a modern truck, look what your axle does, at times it goes where no axle has gone before.

Not talking about older MV system, talking about now. W'ere only talking about 11 years.

You have the leaf spring with two contact points, and the middle supported by 4 bolts with possibly some torque bars. With the M35, you have a reversed leaf spring, NO contact points other than the spring pressure and one or two torque bars. The design is inherently less stable and susceptible to catastrophic failure

Are you testing me? Looking for a reason to ban? Been looking at private messages?

Tires are good. Sprayed soapy water around all tubes inlets including from the rear side of the rim. When I spray into the hole through the rim I get bubbles.

Are you saying having 4 leaf springs in back? Have you seen the m35 articulation at full deflection? It's pretty impressive in my opinion. Personally, I have never heard of a failure except on older torque rods.

Okay so they failed to find the A3 rod about to fail with 5,000 miles on it?
Still doesn't address my point. You have ONE point of contact with the leaf spring leaving all kinds of failure prone issues.

 

[doghead]

How do do know it really has only 5000 miles on it? Suppose that torque rod is original to your 40 year old chassis?

Rubber deteriorates. The design is not flawed.

You didn't answer my questions posted above.


Are you always paranoid?

He must have stayed at a Holiday Inn Express last night .

He also hasn't ansewerd if the o-rings have been replaced .

Suppose I was an engineer? I've built a lot of things, the design is non-redundant. Doesn't take an idiot to see that. One failure leads to catastrophic failure of your brake lines leading to death or injury.

Paranoid enough to understand you have access enough to change my sig line, which you have. So you have access to everything I post on this site. My IP even. Paranoid? No, realistic.

Well I don't think the tires are 20 years old considering the truck was rebuilt in 1998. I wish, cause then I wouldn't have to pay half the registration cost.

I am confused, Thought you said you drove truck. Semi right? Your semi has leaf springs? If i where you i would be more worried about your $ making truck. Havent seen an OTR truck that did NOT have air bag suspention in quite some time.

It's all most the same as a Mack camel back suspension and it is not a poor design.

One thing you may be overlooking. These trucks were never made to federal saftey standards for civilian on road use.

They are special purpose built military trucks.

Don't other than the odometer and the minty condition of the truck. I would find that odd on an A3.

Just because you say the design isn't flawed doesn't make it so. It is if you look at subjectively at it.

 

[doghead]

The whole truck is flawed in hundreds of ways, if you look at it subjectively.

 

[ODdave]

Personaly i have never had anything close to a rim or torque rod faill. I think i have heard of 1 or 2 rods fail, non catastrofic as they where off road twisting the truck up. I think you would be better off finding a economical cure to duramax injectors or 6.0 head gaskets

This broke in my yard driving over gopher mounds in the back yard. Seriously? Special built military trucks to the lowest bidder. The fact that one rod failure will cause you to have brake failure speaks volumes. POOR design. How can you argue that? Put a steel shield over the brake line if the rod comes off or breaks.

That's the point. It's a poor design. I thought these trucks would be better built and better designed, They're not.

Now i am really confused, You have an A3 and had a brake failure and couldnt stop due to a broken rear line? What am i missing?
