1990 300zx na Possible differential problems? please help!

[tdcon2]

basically whenever i turn and give the car a little gas through the turn it feels as though the diff might be like catching and then giving and it jerks the car pretty bad, ummm yeah thats as best as i can describe it. It doesnt do it when i leave the clutch in. This all started after my back tire rolled over a curb the day before. If you have any idea what might be causing this or know the symptoms of a bad diff please let me know, thanks.

Do you mean it feels like the rear is chattering?

[tdcon2]

I'm not sure about chattering. It feels almost like hitting a pothole, except its only the back tires. It does it only when turning, doesn't do it when i engage the clutch, or put it in neutral through a turn, has a tendency to do it less in higher gears.

Scenario: You're going around a corner with some speed and your foot on the gas, you feel g-forces pushing you against your seat and the rear end feels like its trying to slide but instead feels really bumpy, like a chatter. Is this what you're talking about?

[tdcon2]

yeah that sounds about right.

Differential bushings. About 3/4ths of the way down the page. If you're mechanically inclined and have jackstands and some tools, I'd say do it yourself. If not, either find a friend or take it to a mechanic.
