    Sudden Vibration Issue Under Acceleration HALPPP

    So today a lil bit of off roading (had to go over some bumps to get back to a lake, but nothing crazy at all) I started having some vibration issues. Its only over about 3k and when your on the gas hard the seats shifter shake (actually the whole car presumably). My friends guesses are the drive shaft (weights fell off?) or the motor mounts. Ive never had this issue before. Any help guys? I lifted the car up on stands and couldnt see anything really messed up, but then again im not sure what to look for.

    Motor/trans/diff mounts, bad guibo, bad CSB, damaged half shafts, or binding u-joints in the drive shaft are all possible causes. But if it only happens when the drive train is subjected to high torque loads my bet is the drive shaft and CSB. The fix for that is a new drive shaft & CSB or a rebuilt drive shaft and new CSB.
    The car makes it possible, but the driver makes it happen.

      Does it makes sense that they randomly went out suddently and not start with a small vibration and get worse up to this point?

      Thanks so much for the info. Any ideas on difficulty for a newbie mechanic or price for a professional to do it. Im having my uncle help me replace my clutch in the comming month so i guess it might make sense to this then too.

        Could be many things as mentioned, but I'm putting my finger on the guibo going out from the description

            So someone else suggested it might be my differential/axle, which gives me an excuse to upgrade to a lsd too. Might drop it off at the shop to have them look at it and let me know what wrong, then might do the work myself.

              Do you think a clutch on the complete end of its life would cause this?

                Sounds kind of like what mine did when I r3v'd the rear subframe and bushings. stepping on it would result in the driveshaft contacting the subframe, and unhappiness ensued.

                Welded the subframe back up with a reinforcement plate, new bushings, and I'm back to beating the crap out of it.

                  After further inspection everything was OK except for the guibo which is torn up, cracked, missing a bolt, and showing the inner straps =O
