    vibrating after 5speed swap

    Alrighty guys so here's the deal. I did a 5speed swap on my 88 325 and used the parts from my wrecked 89 i have laying around for parts. I also installed a 373 lsd and solid condor speed shop mounts all thru the car.so at any speeds after 40 the rear and starts to virbate pretty bad. Would i need to balance my driveshaft or maybe refurbish the lsd??? Any input please??d

    my guess is your driveshaft, if you dis-asembled it and put it back together off balance that could be whats causing you rproblem

      How far back? Do you feel the vibration in your seat as well?
      Put your hand on the transmission tunnel and see if you can find where it's the strongest.
      My guess would be, if you're using only parts from the wrecked car - it's your CSB or you just need the driveshaft balanced - see if you've got any significant play in the u-joints as well - that could cause vibrations at higher speeds as well

        you installed condor solid mounts everywhere, did not expect more vibration?
