Technical Rear Axle Straighness Question

I'll bet the OP has a rock stuck in between the tread on a tire.

 

Vinny says check for mud stuck inside the wheel. Youts never think to check there.

 

^^^^^^^^^^^^^^ WTF!!!!!! DOES ANYBODY READ THE POSTS ALREADY UP BEFORE THEY START TYPING????????????

 

Guess not , but it does give chuckle, Maybe update the title , glad you found it . now you know your car a tad better so all is not lost.

 

Now it's all fun and games to get Dirty Old Man's blood pressure up.

 

It’s working!

I wonder if there is maybe one lug nut that is oversized? (or loose)

 

SORRY FOR NOT READING ALL THE WAY THRU FELLAS. MAYBE SOME GOOD INFO FOR SOMEONE ELSE FIGHTING A VIBRATION. MY BAD! JUST TRYING TO HELP SOMEONE OUT.

 

can't blame it on being a Dodge..

 

Why don't you go ahead and press that Caps Lock key one time?

All caps is the internet version of yelling at someone.

 

The only way to get my blood pressure up is to squirt chicken shit between your 2 front teeth at me. Try it! it'll run my blood pressure up every time!

 

Work computer. We have to do everything in caps so I just leave it on. Hope I didn’t hurt any feelings.

Open wide.....

 

Thank you for reporting back, with detail, on what the fix was.

Don't feel like a dunce. You fixed it, and the next guy with this problem might find his fix here, too.

 

I thought of a lot of things but the cure sure wasn't one of them.
Thanks for reporting the fix. I'll add it to the list of things to look for.

The reason my shackle bushings failed was that they had insufficient travel to compensate,for change in spring length as they compressed. Therefore, the weakest link, the small rubber bushings were basically sheared in half by the shackle bolts.

In order to prevent that from recurring, I made some "offset" shackles that added 3/4" of travel and put the shackles at near vertical when the suspension is at rest. This should solve my problem.

 

What I have Read:

I know many think that this is a form of hollering, shouting, or so on. But
no where can I find info on the net that supports this as a Law, Or Mandate. Only as "Netiquette Guideline" . All I can find is
that Shout, hollering is a VERBAL action, not a writing action.

So in short, there are several reasons why a person posts messages in all caps.

1: Could be a visual problem, that cannot be corrected, even using larger print

2: may be a physical problem. Like Arthritis, lost of fingers, or limb.

3: Could be a person is not that great with punctuation.

4: Out in the real world, CAPS are used a lot in the corporate world, and
maybe the person is use to typing that way.

What ever the reason, if the CAPS bother you, just delete the message.

DO NOT post a message telling someone not to use caps. That is more
offensive then the caps are. It is also consider abuse to another member
if you post a public message telling them not to use them.

 

Now that's funny. Haha. <SEE ?( I hope you meant it to be.)
"DO NOT..."
(As in " WARNING!!! DO NOT...!!!")

Besides, caps shouldn't (always) be taken as offensive. It's just a "NOW SEE THIS" thing.

 

Amazing. I was gonna say knuuter valve. Seriously thanks for reporting back what you found.

Hey @rockable, I'm unclear how the offset shackle solves your problem. Would you not have to re-locate your top shackle bolt rearward to solve the issue? I'm not sure the shackle shape makes a difference.

 

Agreed.

Having said that, the shackle, as pictured, whether modified or not doesn't appear to be 'wrong' in my eyes. Possibly the original issue was more to do with inferior quality parts, or fitting issues? For instance, they shouldn't be finally tightened up until the weight of the car is on them, as otherwise they're locked in in the suspension relaxed position and are then permanently stressed when the suspension is loaded, leading to premature failure.

I just noticed (never really thought about it) that my email message notification says "The HAMB. DO NOT REPLY TO THIS MESSAGE!!!!!" (Ha x 7)
I just see it as a sign of exasperation. Like they get 50,000 replies saying "Thank you for notifying me that I have a message."

 

OK, "Netiquette Guideline" then.

 

I'm still trying to figure out how to turn off the capital numbers.

 

No, I think this works just fine. The original shackle was straight and it moves though an arc of about 50-60 degrees. It was already at about half of that arc before I changed the design. This shackle will move completely through the arc since it is nearly vertical while sitting in its normal position.

 

Again, the key issue is the top pivot point at the frame, and the pivot point at the spring when it lengthens and shortens as the suspension travels. Those 2 points remain unchanged. The shape of the shackle between those 2 points is not relevant. If the spring is allowed to slide (removed from the shackle), at full suspension compression, how far rearward does the spring eye travel? Is the arc of the shackle capable of intersecting that point? You may need to move the upper mount rearward, or extend the length of the shackle in order that it can meet the intersect point.

That said, as @Happydaze notes, perhaps the real issue is the quality of the bushings.

Not trying to be argumentative, just offering advice, and as I said when your car first hit the road, I like your car.

 

WHAT?

Ooops, sorry, had to...

 

Ok...maybe this poor quality shop sketch will help to demonstrate what my words were unable to convey. Sorry it's sideways
