The DC special treatment

[JKibby]

Well for those of us who have a howl in their drive line it appears DC is going to take care of us My truck is on it's second rear end which howls between 60 and 70 and this is a complete replacement for the original. I have the 3. 73 without LSD. My truck has been in the shop for a week and I've been told be happy DC is on the job! All I've been told that DC's fix is a rubberized material that is heat shrinked to the drive shaft and there is no idea how long this will take or who is going to preform this operation. Getting info is like pulling teeth but will give an updated story when I finally get my truck back a month from now or when ever this super scientific band aid is applied to my truck.

Hey Guys,



Did I post this in the wrong forum?

 

[MMeier]

be happy DC is on the job....

frankly I'd be scared crapless myself if I was told that by a dealer !!!!

 

[Big MAK]

This forum will do fine. Personally; it made more sense to me when it was "Engine and Drivetrain". Rear axle is definitely drivetrain. So is transmission.

Heat Shrink on the driveshaft? I don't think I've ever seen that.

Ill be glad when Im out of warranty.



D. C. has terrible customer relations period.

Not much is new then. Stuff like this was happening when my first gen was new. Take it in to have warranty work done to the CTD, and the techs did not know anything about it, and then they would treat my dad and I like we knew nothing about diesels(My dad farms and has had diesels for 30+years, and I am a cat diesel tech). When my 93 was bought by my dad new, the salesman told him to go across the street and fill the tank at the truck stop. He then proceeded to tell him to put #1 diesel in it, because it was better quality fuel(this was in September at about 50 degrees outside):--) . My dad then told the salesman"You just proved your intelligents on diesels" and walked out with his new truck.



Not that all dodge dealers are bad and dumb. They have prolly came along way, but they still have along way to come too. There is some good ones out there, they just have to be found.

kind of like when service writers upsell a tune-up, then try and upsell you on an upgraded spark plug , wellllll, hopefull no one is that dumb

Two Weeks Ago Somewhere Deep in the Anals of Chrysler Warranty Headquarters...

Say Bob, have you been tuning in to TDR and seeing all of this ruckus about a vibration at around 2000 RPM on the new CTD's? Bob, I figured maybe you could wrap your big CAL TECH, MIT melon around this show stopper and maybe give us a suggested fix... Four Days later, Bob reports back. Say John while the wife and I were in bed the other day it came to me... the fix for that vibration issue, shrink wrap the shaft!!



I think a shaft balance problem causing the vibration and you know we have all of that extra saran wrap laying around from the Halloween party. We need to balance the drive shaft, and rather than removing and spinning the shafts and applying metal weights, why don't we shrink wrap the drive shafts in an attempt to muffle the vibration.



Tune in next week for another stunning episode of BOOBS with BIG BRAINS!!!!Oo. Oo.

It might be a fix- What is the natural frequency of a shaft of that length and diameter. If it is close to any other speed or vibration input- #Teeth on gear, RPM, 2x RPM, 3XRPM, etc- could get the howl. Then a dampner would work. Or maybe they are grasping for likely straws Just anothe SWAG - Scientific Wild A** Guess

 

[PJensen]

Years ago when Chrysler was a real engineering company... . they use to have a large weight on the drivshaft to dampen out vibration.

 

[Peter Campbell]

If I remember right there was also a cast iron weight with rubber isolations bolted to the end of the tailshaft- some sort of driveshaft vibration dampner.

Shrink wrap. . hmm.



My guess is we will be looking back at this solution from the future and chuckeling about it. Shrink wrap hmmm

 

[Tardog]

Had an 83 GMC diesel that had the driveline vibration/howl thing. It definitely came from the drive shaft. Service dealer drilled a hole in both ends and filled er up with that expanding spray foam stuff. It made quite a difference. Until I snagged it on a rock and bent it. The new replacment shaft i put in was much heavier gauge which seemed to also eliminate the sound.

Hmmm shrink wrap the driveshaft Hmmmm sort of like a driveshaft condom Hmmmmm.

 

[RobbieH]

I have this same issue, on top of the loud clutch at idle in neutral.



I wonder what the mileage limit is to get this warrantied, anyone want to venture a guess?

RobbieH,



Do you know about TSB 06-001-03? This is supposed to solve the clutch rattle problem. Although, it did not entirely solve mine.

Well Boys,



I got my truck back on Friday. They adjusted the back lash from . 009 to . 005 did not help a bit and I think the howl is slightly louder. They told me today there is no wear problem, the drive shaft acts like a tuning fork and transmits the noise from the rear up front through the drive shaft. Hence, the rubber shrink wrap which is yet to be preformed because no one knows how to do it, so I wait.



I had to drive 45 minutes back out to the dealer to address a coolant leak that was supposed to fixed on Friday but guess what leaked all over my driveway this weekend. We'll see if it got fixed this time. Unfortunately, this is the only dealer I have found in SoCal that will even try to fix my problems. I've been to three others and they all seem incapable of fixing anything but the simplest of problems. For example, ordering a new jack to replace the faulty one the factory sent me.



It has been a rough journey. I've spent 28 days in the shop for 9 separate problems since I pick it up last March and only 11,000 miles. This drive line wrap better solve my howl problem or the truck will most likely be sold. Like I posted earlier on another topic, my current two Toyota's are more reliable than this truck has been so far. I'm lucky I have a spare car and a job where I have a lot of time off.



I'll post the my satisfaction after this band-aid is applied

So that's what people mean by "have a safe trip"!

Just some suggestions, What about trying out a different drive shaft, either off another truck or get them to rebuild yours with a heavier tube so it changes the frequency of the drive line. Shrink wrap might work but I just think that when your warranty runs out who's gonna pay for the shrink wrap flying off as it ages and deteriorates? Sorry to here about the 28 days without your truck, it might require a letter or two to head office. Just think those 28 days work out to 11% of your ownership time as unusable time to you, and that just plain old s**ks. An owner of a new $40k truck deserves better. I hope they make it right with you.
