Open Question

2006 savana gmc .. when going between 50 and 60 if i hit any bad bumps, break suddenly or turn rapidly the van shakes violently. it seems to be shaking in the back end. what could this be?

When it starts shaking i can slow down to stop the shaking .. if i speed up it will only make shaking worse. seems to be in the rear end .. it only rapidly shakes when i hit a rough spot in the road ... in road is smooth no problems but any sudden braking or running over a dip in the road it will shake.

SOURCE: Front end shake

hi from uk from your symptoms you describe may i suggest that as you say this occures only after repeatbraking /when brakes and tyres are heated? this may be a tyre fault? or you may have a a fault with a steering joint? suggest you check tyres for defects on front when you have run/braked and fault occures? look for buge on tyre?inner or outer? also raise each wheel and rotate whilst check for ovality on circumfrence? please come back with your findings or if you req more advice?

SOURCE: Whole car shakes when I hit a bump on the road

I had a similar problem and found that there are more than one possible cause. The simplest and least expensive is to have the front wheels balanced on a dynamic machine balancer. Then, reinstall the wheels/tires and give it a test run. If the problem is gone, your have fixed it.. If it persists, chances are that you have other suspension or shock problems. Get the front end aligned and checked for looseness or slack which would allow the tires to be pointed in different directions at the same time in a rapidly alternating manner. These are NOT things you can do without the benefit of a professional with the right tools and knowledge. A test drive with that professional mechanic will be a good place to start. If you want to save your tires and your personal well-being, it is wise to get this problem identified and resolved quickly. You represent a danger to yourself, your vehicle, your family, and to any other driver or pedestrian or obstacle in your path.. Bite the financial bullet and get it fixed, PRONTO!, or park it and walk.

My 1999 gmc savana van turns over but does not


could be a bad fuel pump, or fuel pump relay. they are having problems(a lot) with the ethanol in the gas on GM products.Fuel pumps sales are through the roof at parts house on GM's. Have a pressure check on your fuel system. That is probably it. Add a can of Seafoam to your fuel every 3000 miles to alleviate this problem.

04 Dodge 2500 4X4 shakes violently after hitting bump at 55 mph +


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.
