Hi,
I have a 91 JDM TII. As i turn tighter corners at very low speeds, only when its been driven a while and its good n' hot, I'll get a shuddering in the drive line that shakes the whole car as if the wheels don't wanna spin at different radii. At first I thought it may have been clutch chatter, Since it usually happened as I was leaving a stop sign and turning, but I've since replaced the clutch and it still does it. I'm believe its related to the viscous lsd, I'm just not sure if the whole rear end is damaged or if perhaps, its related to something else. Any input is appreciated. thanks!

get the diff serviced. see if that fixes the problem.

 

Check your u-joints on the driveline. One of them is shot!

 

Yeah, I had a similar problem. I didnt know where to start so figured it would be the clutch, I have around 162XXX miles on it so started there. Had that replaced and then I was informed one of the u-joints was cracked/damaged so and purchased a driveshaft from a guy on here and swapped it in. Now when I drive it I cant help but smile because it is smooth again with no more rattling from the interior. Hope it helps.
