Car vibrates/shakes/shudders during driving

[wtftoy]

I hope everyone had a good AND safe new year!

Back to topic....I drive a gen 4, 98 camry le v6 automatic w/ 87k miles. Just recently it started to vibrate/shakes/shudders while in motion. When its accelerating or at a coasting, you can feel it but its most noticeable when its slowing down. This happens at all speed. You can feel the shaking everywhere, from the front seats to the back. I checked the tires, took them all off and inspected them and they look fine, they spin fine too so I don't think thats it but I will be getting new tires soon, HOPEFULLY thats the problem.

Funny how my camry has ALOT of problems....it seems like one after another!

Any help, suggestions or anything would be greatly appreciated.

I also forgot to mention that I did my sparks plug with ngk plugs and wires a few weeks ago but this didn't happen RIGHT after it.

Make sure your wires have good contact. Push and twist them in.

Did you change distributor cap and rotor along with wires?

If you feel that the shaking is from the tires/suspension system, rather than an engine missfire, then this is not something you should leave alone until you have time to diagnose the problem. If you cannot diagnose this problem yourself, then take the car to a professional right away. Broken, worn, or bent suspension components can potentially be very dangerous. One thing you can do to check some things yourself, is to jack up the front end and then support the car safely on jack stands (and I do mean safely). Then start the car and place it in drive. Then go outside in front of the car and get down on the ground. Observe the front wheels and the axles and see if either are vibrating as they rotate. It would help to have another individual to press on the gas pedal, as you observe from the front. You could have a bad tire, a bent wheel or a bent axle. You should be able to determine these possible problesm by this simple test. Other suspension components will be more difficult to check, so if this test doesn't show the problem, take the car to a professional, as soon as possible as I stated before.

Yep checked all that. My gen 4 v6 doesn't have distributor cap or rotor.

--NVM!!! EDIT!! I thought I did something wrong...but I was right. My spark plug wires are all good, in correct order.---


---I'm wondering because I just looked at the firing order, cylinder arrangement. I bought these wires http://www.sparkplugs.com/more_info....17493&pid=3358 .
But one thing I noticed was that I KINDA wired it wrong.

The correct wiring is =

1 3 5
2 4 6

So the wires should connect like this

A C B
B A C

But mines are currently wired like this =

4 6 2
5 1 3

So I'm going to check that out but I doubt its that. I will report back.---


I'm PRETTY certain its not my suspension, even though they are stock and have the famous annoying camry rattle. I will be taking my car to the shop if I can't find it.

Thanks for the replies guys. I will report back.

I checked that while I was looking over each tire this passing weekend. They all seem to rotate correctly when I checked but we'll see.

Anymore ideas?

Broken engine mount or two?

OP,
As a follow-on to what Mike wrote, you might try to rotate the tires and see if the vibration changes at all. That would indicate a wheel/tire problem not immediately evident by visual inspection.

Good point. It's hard to notice a broken or shifted belt in a tire unless you really know what you are looking for. Rotating the tires back to front could help determine if that is the problem.
