The R51 Pathfinders have a driveshaft that have the same you join fittings on both ends and can, believe it or not, be installed backwards causing all kinds of vibration if the technician did not mark which side of the driveshaft is toward the front and which side of the driveshaft is toward the rear. Hopefully, the technician marked the pinion flange and the U joint at the end of the drive shaft on the rear differential area so that the driveshaft is install the correct direction, taking into affect the balance as well. If there was an error in any of this, and the driveshaft was not reinstalled exactly the way it came out, you will have vibration especially under acceleration. Good luck!
