I feel a bump in the foot pegs did not feel this untill i had the front tire changed

you will have to use process of elimination, is tyre bead marker on side of tyre running true?

The only thing I can think is you have a tire with a bad or broken steel belt. Assuming your tire preasuis up to spec. Take your foot and push on the side of your tie and watch fo a rocking motion. Now do this to all the tires and see if their is one that I noticeably different than the rest. Try rotating tires front to back and see if that changes the symptom. Don,t assume that because the tire does not have lot of mile that it good. A well placed curb smack can wreck the integrity of the side wall, and if suspension is good that's really the only thing that could cause this problem, good luck [email protected]

MAY BE SOME ICE STUCK OUTSIDE TIRE. SEE AND SCRATCH CLEAN IF TIRE HAS AN ICE BUMP. OR ELSE THER MEY BE SOME THING ATTACHED TO TIRE BY PIERCING.

Usually a BUBBLE in the tire or you need a tire alighment

If you never had the problem from 2006 until the new
tires went on you have both a financial issue,as well
as some tough diagnostic work to do.

I don't have all the answers for you but the tires
are the focus of the starting point.

I would rotate one tire at a time from the
front to the back
Mark the inside of your wheels with a sharpy,
1 & 2 on front 3 & 4 on the rear
Make a chart on paper of the positions your
tires are at. You should have that for all your
vehicles.

You may have a bad tire that is so heavy on one
side it won't balance out.

I have a Lincoln LS that I run 42# in front and 38#
in rear and it is not at all hard or bouncing

If you can absolutely verify that there are no loose components in the front end I would start looking at the tire for belt separation. This can be detected by rubbing your hand gently over the tread area. Feel for bumps,bulges, and irregularities. It should be fairly obvious.

You can also try putting the tire on a different location and see if the symptom moves to the new location.

See if you can bounce car and replicate the noise. If you can, you should be able to find it, and put your hand on it. Stabilizer bushing are a place to look, both at the lower a arm and on the frame. If you narrow it down to the strut, it will need to be replaced. The front trans mount also goes bad, try putting it in drive with your foot on the brake and give it some gas and see if the engine moves an excessive amount.

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.

Have you tried driving over a bump whilst also applying the brakes? (Right foot on gas, left gently on brake - with no one behind you!) If the noise goes away, then it could be the brake pads that are not fitted correctly. Only posting this, as this just happened to mine...the mechanic took it over bumps and noise was there. Applied brakes whilst going over bump, noise went away. Replaced badly fitted rear pads (had been bodged by another garage) and the problem was solved.
