#75 of 80 Vibration between 30 and 40 mph by lareau

Apr 10, 2012 (11:54 am)

I have a 96 Dodge Ram 1500 extended cab which vibrates at the speed of 30 - 40 mph. The vibration is felt all over, steering wheel, seat, etc. There is no vibration at speeds below or above these speeds. I have had my tires balanced and partial alignment as I was told that the wheel bearing should be check as there is some play but not much. And after I get them replaced to come back and they will do the compete alignment. A friend said that the drive shaft could be out of balance. Can a drive shaft go out of balance? Can that cause the vibration or can it be something else. Any advise would be appreciated.

Thanks

answer 96 dodge, YES IF A DRIVE LINE IS OUT OF BALANCE YES IT WOULD CAUSE A SHAKE.AND SENSE U HAD TIRES BALANCED THE ONLY THING LEFT WOULD BE DRIVE LINE HAVE IT BALANCED AND OR REPLACED. WOULD HAVE A CERTIFIED DRIVE LINE FACILITY INSPECT IT BEFORE ANYTHING ELSE.
GOOD LUCK.......

I didn't even have to read all of your complaint. I am an ex District Service and Parts Manager for Chrysler 1996 - 2008. I heard this complaint ALL of the time and experienced it myself during multiple customer complaints and on my own demo units. Chrysler has known about this problem for YEARS. Their response has varied but the most prevalent response was to tell the customer to put sand bags (or any type of weight) in the bed of the truck. That would reduce it but not eliminate it.

If you have aftermarket wheels & tires then you have just taken yourself out of the loop of repairability (unless you get an eccentric mechanic to modify the suspension system for you). Chrysler will deny responsibility and blame it on road surface. I can confirm that aftermarket wheels and tires make it worse because I had a customer bring his vehicle to the dealership with that issue and we removed his wheels & tires and replaced them with a set off of a stock unit. The issue was resolved to the extent that stock wheels & tires will allow it to be but the issue was clearly intensified by the customers aftermarket wheels & tires. You should have seen the look on the customers face as we proved the issue. Funny. But the customer went on to say that was the last Dodge he would ever buy.

If you'll notice, the issue is exacerbated on freeways that are of cement construct. In fact, I've had some customers tell me they allegedly had to slow down because of the violent shaking they experienced. In other words, they had to adjust their driving habits to accommodate the engineering of the truck. On the other hand, when driving on BLACKTOP the issue is not as pronounced.

I can tell you without a doubt you will NEVER get rid of this issue. To Chrysler, the amount of customers that complain is not worth the cost of making an engineering adjustment in future production. Most customers simply accept the issue and move on. Personally, I would never own one for this reason (and I had 12 years at the company). Get used to it.

I have 2012 Ram 1500 ,5.7 Hemi, 8-6-4 cylinder system in cruise on hwy driving. Vibration is through entire truck starting at 35 mph to 80 mph with cruise control on in the Eco on Mode where cylinders drop out to save gas regardless of speed and cruise. I get 14.5 m/gal regardless of driving habits from driving like an elderly person to a hot rod driver. I should be getting close to 20 m/gal when cruise is on and running on 4 or 6 cylinders in cruise or foot feet. the vibration is in cruise and foot feed driving. I should be getting 16.5 m/gal city driving at least. Dodge is giving me a run around and does not know what the problem is. Had service and mechanic in truck at same time and they felt vibration in action. Been in shop 4 times and no results in fixing problem. They claim the 8-6-4 system automatically causes this. The transmission is looking for another gear when the Eco system is trying to cut in and with no avail does not happen. Results of 14.5 m/gal only, gas mileage is not what they claim.
