I bought my truck used last September. It's seemed to have this horrible "bounce" especially around the 40-45mph range. It's very inconsistent. At times it will drive like a cadillac and at others it will feel like I'm about to get launched out of my seat and hit my head on the roof. It's like my entire frame is flexing in the middle. The dealership said my tires were out of balance. They rebalanced them but it didn't help. I'm thinking I might have a tire out of round... I don't know. Also, whenever I hit a bump at highway speeds, the truck seems to take a while to recover--it shimmies for a while before it smooths out. I believe my rear shocks are shot. They have rusted leak-down marks on the outside of them. I'm going to replace them but I'm not sure that shocks would cause that big of a problem. One thing that has been consistent is I noticed that never have any problems when I either have a load in the bed or am towing a heavy trailer--anything that can put a significant load on the rear of the truck. The bounce always seems to come from the rear or right under my seat. I don't have any wobble or vibration in my steering wheel. Also, I've rotated the tires. That seemed to help for a little while but now it's back to the same. Any thoughts?

Sounds like the shocks to me. If they are showing signs of leaking, they need replaced. It can make a huge difference in handling and safety of the truck. I would start there

That sounds like my original problem, except my steering wheel vibrated. The whole truck would bounce and vibrate horribly. I found the outer tie rods to be very sloppy, changed them, had it aligned and now i'm just down to an intermittent mild to moderate vibration that I haven't been able to track down. have had a couple of responses on here for things to check, but none of the suggestions have been the problem. good luck

I'll put a jack under it and check all the front end parts. The rack and pinion was sloppy when I bought it so the dealer replaced it and had it aligned. I've got excellent response/tight steering but I'll double check everything to make sure I haven't overlooked anything. Thanks Mike.

Installed OEM rear shocks yesterday. Seems to ride better. It definately stiffened up the rear suspension. Truck recovers after the rear tires hit a bump now--no more bouncing. But, I haven't put many miles on it with the new shocks. I think I'll be able to tell for sure when I get it down the interstate and see how it handles.

hey, I think you have a cord broken in one of your tires, you can check this by rubing your hand around the tire, you will fell it, also look for anything that looks like a knot in the tread , if you cant see anything,put your spare tire on one side and test drive your truck,keep changing the tires with the spare till the vibs go away then you know which tire is bad, hope this helps jessman

Ok...this sounds like the same problem I've had for almost two years now. I experienced the vibes just as you mentioned. Mine is the worst at about 65-70 mph but I can feel it at all speeds at times. I also have the intermittent with the truck sometimes riding very smooth. For the first 5 years I owned it, it rode like a dream...like a cadillac. Then I started feeling the vibration. My first thought was tires. Took it in for rotation and balance - no improvement. Took it back ...same thing. Took it back a 3rd time and the tire guys found a wheel rim out of round. Had it the rim trued up but was told that the tire was now probably worn out of round. fast forward 5 months trying to "drive it out" with no luck. Replaced all four tires. Still had vibes....tire store agreed to replace tires again...this was like 2 weeks later. In the meantime between these tire processes I had ball joints and stabilizers replaced, front end aligned, etc. Now I'm really ticked because this truck used to glide, not to mention I have no idea how a rim would have gotten bent! So.... I continue to ask questions around town as my vibrations get even worse with time. One friend said it feels like an older car he had in the 90's that he eventually replaced or had the drive shaft balanced. He said some drive shafts are factory balanced but there's a chance a weight can come off of the shaft...then it's out of balance. I called a place in Charlotte today that said they can check it out. Have any of you guys ever had a bent or out of balance drive shaft? This would make sense since the tire balances/rotations, ball joints, stabilizer rods, wheel repair, etc. have all had no effect in improving my ride.
Frustrated,

Had the same bounce/ vibration with my 2500 4x4 and found that the outer axle u-joints where wore badly and when you hit a bump or creveas running across the lane it would cause the axle to go off of center line rotation causing the vibration/ bounce until everything centered it's self again. After market u-joints where $90 each Cdn to buy.

Vibration issue

Hello,
I am new to this site this morning because I have multiple issues with my recently purchased 2006 Ram 1500 SLT 4x4. I noticed your post about Wobble/vibration issue. I have the same problem with mine. I first started by installing brand new Michelin LTX 20" tires all around. The truck did need new tires. Problem is still there. Then I proceeded to have the front coil over shocks replaced. The old ones were fine no leeks, no signs of wear. Problem is still there. I even put a bed cap made by A.R.E. not to fix the problem but just cause I needed one. Problem is still there.
I have yet to change the steering box do to lack of funds and the need to fix a transmission shutter I have at 1000rpms.
Did the rear shocks help after this amount of time? or do you, like me ignore it due to frustration.:SHOCKED:
Tim.
