When I'm driving down the road, regardless of the speed, and hit a rough spot, bridge overpass, or any medium sized bump my truck starts to shake significantly. This is highway driving. I brought it in and was told that my front end was "tight" but my tires were shot. I only had 40,000 miles on them, but I replaced the tires yesterday. The shaking continued. I brought it back in and had the U joints inspected along with the transfer case fluid, but again everything was fine. I was told to shift into 4H when my truck starts to shake and shifting to 4H eliminates the problem for the short term, but I don't want to drive around in 4H all of the time. This has been going on for less than a week. Today I took it down a rougher blacktopped road and the shaking happened even in 4H. A tap on the brakes is all that was needed to stop the shaking. This is not a vibration, it is a loud, roaring shake that makes me feel very unsafe in my vehicle. Any ideas????

-Roof will not cause that. Shaking steering cause from un even wear front tires.


Good luck

Have you cked the bushing lower and upper

check u-joints and sway bar bushings

have the struts checked

Have the front shocks check out, the shock helps keep the tire to the ground, when hitting bumps.

try changing the tires . you may have a broken bead in a tire, which flattens when you hit higher speed.

Why drive side bearing could be a bad other.balance yes, tie rod could be bad.

The bumps do initiate the shaking. When my 2006 Ram 2500 4x4 started shaking, I had just had it aligned that morning. A month or so before that alignment, my passenger side outer tie-rod broke while driving down a rock road. I replaced it with a heavy duty MOOG tie-rod end. Anyway, the same day I had it aligned I was driving back home from a job and towing my bobcat behind me. I hit a bump and the truck did the "death wobble" with the front end shaking violently up and down in an alternating fashion (one tire in the air while one tire on the ground and then vice-versa). I changed the tires first (which were worn-out 305/75/17 mud tires). Since the day I bought the truck new in Jan. 2006, I've had larger tires on the truck than the tiny 235/75/17s that came with it and I've done a lot of heavy towing with it and never had a problem until this alignment was done at Sears. I;m still trying to figure out if it was the alignment specs that they used or if the problem coincidentally started that same day. I also changed the steering stabilizer. Neither the new tires nor the stabilizer/damper helped the problem. So I changed the other outer tie-rod end and the upper and lower ball joints (all MOOG with grease fittings). I turns out they were worn out. So, the truck no longer shakes violently up and down when I hit a bump. That problem seems to be in check. However, now when I hit a bump the truck's front end wobbles side-to-side. I can do a few things to recover from it. I can hit the brakes pretty hard and sudden (which can cause an accident on the interstate), or I can **** the steering wheel side-to-side a few times (from 10 o'clock to 2 o'clock) and that stops it immediately...until the next bump in the road. Also, if I let my foot off the accelerator just before hitting a bump and let the truck coast over it instead of power through it, sometimes the truck will ride over the bump without incident. I found out yesterday on a 5 1/2 hour road trip that if I did 80 to 90 miles per hour and powered through every road blemish, the truck rode fine...no shaking at all. I suppose the high speed forces the tires to stay straight when they hit a bump. Lastly, to confuse my problem solving attempts further, sometimes the truck rides like a cadillac (for an hour or so) at regular speeds and no matter what bumps I hit. Then without worning, the front end will loosen up and get that sloppy feeling again and the wobbling comes back at every bump...until the next time it feels like tightening up and driving right again. I have no idea what to do now. I'm going back to Sears today to have them check their alignment. Other than that, all I can think of is to change the rest of the steering components and check the steering box for malfunction. I hope someone can help all of us Dodge owners out off of the road tested info that I've just provided. Dodge doesn't seem to care to address the problems with their trucks front ends, and we need a solution before people get hurt or die. I was almost run over by an 18-wheeler trying to figure out how to handle the shake. I can't afford to buy another truck. So I need to fix this one so I can keep working. If anybody has a concrete solution to these problems, please let us know. I've read 20 different opinions from mechanics on these blogs, but nobody has said yet that they fixed someone's truck with these problems and have since heard from that customer and everything is still working fine. Opinions are helpful sometimes, but they're also confusing when they're conflicting.

It is possibly the steering stabilizer. It can give a death shake when hitting a small bump at higher speeds

May check your ball joints and tie rods. Also could be your shocks.
Does it seem like its more shaking on the left or right? or even?
