Default Weird turning shudder

First off the car is a 97 SE

The issue is when I turn and accelerate hard out of it the car shudders. If your trying to pull a U-turn and then merge into traffic its a pain and I'm wondering whats causing this?

Thanks in advance,
Andrew

well, my car was doing something similar to that, and it turned out to be a wheel bearing. not sure if you have the same issue, but you might want to check.

Could be a wheel bearing, like marquette says, but your description is classic for a bad drive axle. Also, carefully check your ball joints and tie rod ends - they are under a lot of stress under acceleration while turning.

Theres no clicking but the car has a shimmy at around 68+ mph...I was thinking it could be a bad CV axle...

A normal sign of a CV being bad is to head to an empty parking lot..

Then turn the wheels all the way to one side and drive slowly.. then to the other..

You'd usually hear a clicking.

Check the fluid level on the PS.

It could be a bad bearing.. it could be simple enough like brakes that rub when the pressure of a hard turn is on..the disc can flex and touch the pads.

Could it be more movement in a softening motor mount or worn mount letting the motor and tranny move around? Or tires might be the factor. Try running pressure high like 35 and then at 30 which is factory suggested... to see if it'* them. Alignment? The tires are trying to turn different radii circles during a tight turn; maybe the alignment needs touchup. If no noise, I wouldn't be real concerned.
