    Hey everyone, I need your help! My 2009 volvo 670 with a Cummings motor has started the "volvo shakes"... Around 50mph and up the cab shakes violently while giving it fuel, it dies down a little bit once off the fuel... Also while this is happening the RPM and speedo needles dance a little bit, I've had this problem with 2 different volvos when I was working at Knight but I just traded out trucks and never found out what causes it.... Does anyone know exactly what it is? Please help.... Thanks family...

    Most Volvo drive lines are the maintenance free type without grease fittings. Ujoints and slip joints can start to seize up and cause issues like this.

    I would also check the yoke nut on the rear of the transmission. If it is a little loose it can jump around and mess with the speed sensor
