lots of rumble in the back...is it a Drive shaft problems????

[redline828]

Hey there, im new to the club. thanx letting me join!

i have a 92 DOHC s13

So ive done my homework and i can figure out the rumble in the back of my car only in 2nd gear. On top of the rumble, my shift knob shakes like crazy specially when taking off in 1st gear but no rumble and when i give it gas in second gear the back of the car below the rear sets rumbles like crazy, there on only makes a strange little humming noise on 5th gear. this is driving me nuts!!

i originally thought it was my motor & tranni mounts so i changed them all with new NISMO ones and it did help but it didn't solve the problem.

this is driving me nuts and i cant afford to replace my tranni and drive shaft all at once and that not solve the problem. If anyone can shed some light in this issue i would be for ever thankful.

not sure about second gear but the humming could be a leaking diff. that can cause it to lock up so i would check asap.
