i am going from a 993 2wd to a 993 4wd, and noticed the 4wd car has a vibration/harmonic b/w 28 and 32 mph. speeding up or down. clutch in or out. not tire/wheel balance have changed them.

feel it in shifter, seat and wheel. feels and sounds slmost like the buffeting noise the open sunroof can cause when the windows are up. that is what i thought it was the first time.

any ideas?

Is it part of the learning curve?

sorry are you saying that this is problem is normal w/the 4 wd systems in the 993. and in fact not really a problem?

i thought it may be normal but have never heard any one mention it before.

thanks
