I've had my Ram for a little over a month now. I noticed when I test drove it shook a little at highway speed, but I figured the tires just needed to be balanced. Now it is really getting annoying. I got the tires balanced twice today and replaced the rear tires because they were worn and it still shakes between 60 - 70 mph. Is there anything else that can be causing this? The tires are Bridgestone Dueler A/T 265/70R17's and I've set the pressure to 35 front and rear.

Thanks for any insight.

 

is there any damage to the drive shaft or u joints? i would check the undercarriage for obvious signs of damage

 

With it being an '03 there is a good possibility of a U-joint being shot, but don't eliminate the possibilty of the driveshaft being out of balance.

 

if you have an aluminum driveshaft i would almost put money on it being the driveshaft out of balance...having a bad problem with the aluminum driveshafts...over 70 of them on national backorder

 

go under the truck and pull back and forth on the drive shaft near the u joints, if there is movement, they are bad, otherwise possible and out of balance shaft

 

Casper3380 and HammerZ71 thanks for the u-jointinformation. I'll take a look at the u-joints tomorrow. How would I check out the driveshaft balance?

Hemiyellow is the driveshaft an expensive repair?

 

look for any visual damage on the shaft first otherwise you will have to get it checked. Not sure on the price

 

driveshaft is like $480 reg customer price...do like i'm doing and have a steel driveshaft made

 

Ok I crawled around under the truck this morning, that sucked because it's cold windy and rainy today.

The bottom of the truck is clean, no damage, no scratches, and in fact still looks like it just rolled out of the factory. I do not think it has ever been off the road.

The driveshaft also has no damage and I brought a magnet with me and the driveshaft is steel. Below is a picture of the tag on it. The tag has the company name of Dana Torque-Traction Int Tech Inc, is this an aftermarket part?

The U joints seemed tight too. I tried moving them in every possible direction and they did not move.

Are there any other possibilites?

The tire shop guys are going to hate to see me coming if I bring it back for anotherbalancing.

 

hmm.... is your truck got a good alignment? we have a different front end so i dont know too much about your front end... Is it like a shake or more of a slight vibration....
