Toyota 4Runner 3.4L Engine and Transmission Mount Kit 3-Piece

This three-mount set fits the 1999-2002 Toyota 4Runner with the 5VZ-FE 3.4L V6, manual or automatic transmission, rear-wheel drive. It includes the front left and front right engine mounts and the rear transmission mount.

The 3.4L makes enough torque to tear a tired driver-side mount, and once that happens the engine lifts on takeoff, the fan can get close to the shroud, and you hear a clunk every time you go from reverse to drive. A collapsed rear transmission mount drops the tail of the A340 or R150 and throws off the driveshaft angle, which shows up as vibration at highway speed and a knock on acceleration. Doing all three together puts the drivetrain back at the right height.

Listed for RWD trucks. Check bracket shape and stud locations against the old mounts before installing.

On the job: support the engine from above or with a jack and a block of wood under the oil pan before any mount comes out. Change one mount at a time, leave the through-bolts snug but not torqued until every mount in the set is in, then let the drivetrain settle at rest and torque everything. Tightening a mount while the engine is jacked sideways preloads the rubber, and a preloaded mount tears early.
