  Q: What is the design and function of the driveshaft and universal joint in a Toyota 4Runner?

  A: Before anything else, the Drive Shaft is a tubular construction designed as a one-section type, with both ends bolted to the respective transfer case and differential flanges. The rear driveshaft attaches to the rear axle pinion flange using a bolted flange, and its connection to the transmission or transfer case varies depending on the driveline package. When replacing universal joints, maintain the finely balanced nature of the driveshaft. Marking each individual yoke is advised to preserve balance, and caution should be exercised to prevent dropping the assembly during servicing. On 2WD models, a splined yoke called a "slip yoke" or "sleeve yoke" is employed at the front, with an oil seal to prevent leakage. On 4WD models, each driveshaft is attached to the transfer case by a flange yoke, and the companion flange can be removed to replace the companion seal(s). Proper maintenance involves keeping the driveshaft clean, ensuring balance weights are intact, and reinstalling it in the same position.

  Q: How to remove and install a U-joint?

  A: To remove the Drive Shaft, start by loosening the wheel lug nuts and raising the vehicle on jack stands. Place the driveshaft on a bench with a vise. Mark the shaft and yoke for reassembly and remove the snap rings from the Universal Joint. Use a pipe or socket to press one bearing cup out of the yoke, supporting it with a smaller socket. Use pliers or a vise to remove the other bearing cup. Clean the yokes thoroughly, removing any dirt or debris and eliminating metal burrs. For installation, pack the new U-joint bearing cups with grease, following the provided lubrication instructions. Position the U-joint body in the yoke and partially install one bearing cup, ensuring the grease fitting points in the same direction as the grease filling on the opposite end. Start the U-joint body into the other cup and align it between the bearing cups. Press the bearing cups into position, being careful not to damage the dust seals. Install the snap-rings, using a hammer if necessary. Install the driveshaft, lubricate the grease fitting if present, remove the jack stands, and lower the vehicle.
