2004 Chrysler Pacifica - Loose Steering and Shuddering
Hi All,
I have an 04 Pacifica with a front end issue. The vehicle acclerates from a stop smoothly, but when I start accelerating again once I hit about 50 or higher, the front end shudders as load is put on the vehicle. It doesn't really feel like it is shuddering in a wheel (left or right), or in the steering wheel. It seems like it is coming from the center of the vehicle. It also does shake pretty violently when braking. A more few notes:
- Putting the vehicle into neutral and hitting the accelerator does not make it shudder - telling me that it is not an internal engine issue
- Shifting the engine down a gear while at high speeds revs up the rpms but does not increase the shuddering when under load - telling me it's not a transmission issue?
- Engine always shifts smoothly - no stuttering or hard shifts
- Steering also seems to 'wander' a bit while driving at high speeds
I'm thinking tie rods or sway bar... I popped under the vehicle and all outer boots and joints seem solid (no tearing, grease leaking, etc.).
Any advice is welcome! Thanks!

It sounds to me like you have some suspension issues. I would have the lower control arms checked as well as the rest of the steering components (tie rod ends, CV joints, wheel bearings etc.) I have found that cheap aftermarket components to be junk as compared to factory parts. If you buy aftermarket parts, I would suggest you get MOOG brand parts. You may have some issues with your drive shaft too causing the shuddering at high speeds, which could be a transmission (torque converter) issue too. Sounds to mt like you need to get it up in the air for a full inspection of suspension and drive line parts...

I have the similar issue. But in my case I noticed that it's related to level of rpm usually LOW 1300-1500 rpm while gear shifting. It became much better when I have added additionally 1 L of ATF fluid because transmission was low on fluid and my mechanic didn't noticed it because probably he didn't check the fluid level. So I would check the ATF fluid at the beginning and not only one time: at the beginning of trip (cold), in the middle and at the end when fluid is warm. But I was not able to completely rid out of shuddering because I still feel it just not so much now. So the next thing I would like to do to change ATF fluid and fill the new but still as long as it'is connected to particular speed or gear shifting it's not the suspension trouble. I don't think so.
