Ok so I went out and got new tires, Master Craft Courser ATs made by Cooper tire $650. I watched as they dismounted, changed them balanced them and remounted them. So I'm driving on them the first few days and noticed a wobble from about 35-50 mph. I go back and took one of the mechs for a drive he says its your u-joints. puts it on the rack and there is about a 1-2 inch play in the driveshaft. So get the new u-joints $85. I live and work in a small town so I don't get to open it up until I hit the open road. I got a wobble again but ONLY at 50-55 mph. I'll be taking it back but any suggestions before I go back?? It wouldn't be the front bearings would it, or front shocks?? It's only at 50-55 mph it does this. She has 102,500 miles on her Thanks , H-

 

Did you have the vibration BEFORE they put the new tires on?

 

^^^ Excellent Q

Just because you watched them get balanced doesnt mean it was done right. I watched mine get done to. Hell i even helped pick the big b*stards up and mount them but they still were not done right.

Dont rule out simple things and not double check them

 

DO you have after market wheels?


Reason I ask, I have after market wheels Metal moto's on my rig with stock tires but after installing new 33 meats I had a wobble? Found out I needed Hub-centric rings to center the wheels. Cost me about $30.00 and all is well. I guess the larger meats made the vibration arise?

 

GOD I HATED those tires. They were on mine and were fine for about a year and a half. After 20k miles they would spin out on a damp road. Make a right turn quickly when wet at a light i would end up sideways with hardly any pedal. Stoping down hill when wet meant you were skiing. I only had those 30k miles before i had to replace them they sucked so bad. Not trying to make you feel bad, but i had a bad experience.

 

Hey Hammer: No vibration before the switch of the tires

Weed: I need to go back and have them do it again or I'm telling them I want my $ back

Dark Rig : Naw just have the stock 17"ers on them

That1Guy: You had the same problems? They told me these were great Tires. Cooper makes them as one of their "off" brands

We were driving down I-16 and back from the Walmart near Savannah Ga Airport and it only vibrated at about 52-55 mph. At 60+ it was fine under 50 it was fine WTF??

 

Any chance you know someone with another Ram? Swap wheels and see what happens.

 

Jack it up and run it. See what's shaking...

 

I didnt have a vibe, but the rubber is horrible. Like I said. DANGEROUS in the rain or even wet roads.

I have been driving up a steep hill doing 30 mph. The truck gently down shifted and before i knew it i was spinning and had to let off and baby it up the hill. I have a limited slip rear end and it was nothing for the rear to break loose or the front to slide on anything.

I got a set of bridgestone tires off a new z71 silverado and not had a problem since.

 

If you had NO vibration before the new tires and NOW have a vibration, I would tend to think it's be the tires. Either they didn't Road Force Balance them, or one of them is bad out the box...
