Toyota Tundra Service Manual: Installation

INSTALLATION

PROCEDURE

1. MEASURE EXTENSION HOUSING AND DIFFERENTIAL FLANGE ANGLE

NOTICE:

• Perform the inspection on a level surface.
• Perform the inspection with the vehicle empty.
• Perform the inspection with all wheels on the ground.

HINT:

As the extension housing and rear differential flange angles are necessary when measuring the installation angle of the propeller shaft, measure the angle of the extension housing and rear differential flange before installing the propeller shaft.

(a) Using SST, measure and record the angle of the extension housing flange (A). SST: 09370-50010 Text in Illustration *a Extension Housing Flange Angle: A

(b) Using SST, measure and record the angle of the rear differential flange (B). SST: 09370-50010 Text in Illustration *a Rear Differential Flange Angle: B

2. TEMPORARILY INSTALL PROPELLER WITH CENTER BEARING SHAFT ASSEMBLY

(a) Completely remove any oil or the like and clean the contact surfaces of the propeller shaft flange and differential flange.

(b) for 1UR-FE:

Remove SST from the transmission.

SST: 09325-40010

(c) for 3UR-FE:

Remove SST from the transmission.

HINT:

Measure dimension A (the distance from the front surface of the center bearing housing to the back surface of the intermediate shaft) at 3 places and make adjustments so that the measured dimensions are equal.

*a	Intermediate Shaft	*b	Dimension A
*c	Tires supported and vehicle empty (When using drive-on type lift)	*d	Full rebound position (When using 2 post lift)
	Front Side	-	-

Standard Dimension A:

*1: includes Off road package

*2: includes Sports package

*3: includes YOUTH Edition package

(b) Check that the center line of the bracket is at right angles to the shaft axial direction. Text in Illustration *a 90° *b Bracket Center Line *c Shaft Axial Direction

(c) Tighten the 2 mounting bolts.

4. INSPECT PROPELLER SHAFT ANGLE

NOTICE:

• Perform the inspection on a level surface.
• Perform the inspection with the vehicle empty.
• Perform the inspection with all wheels on the ground.

(a) Measure the No. 1 joint angle.

(1) Using SST, measure and record the angle of the intermediate shaft (C).

SST: 09370-50010

(2) Subtract the angle of the extension housing flange (A) measured before installing the propeller shaft from the angle of the intermediate shaft (C) to calculate the No. 1 joint angle. Text in Illustration *a No. 1 Joint Angle No. 1 joint angle: Angle of intermediate shaft (C) - Angle of extension housing flange (A) Measured Value (Reference): Intermediate Shaft Angle Measured Value (C) Extension Housing Flange Angle Measured Value (A) No. 1 Joint Angle (Calculated Value) (C) - (A) 3°15' (3.25°) 4°00' (4.00°) -0°45' (-0.75°) HINT: Using the following chart, check if the calculated No. 1 joint angle is within the specified value. The tolerance is +/-0°60' (1.00°). Standard No. 1 Joint Angle: Vehicle Model No. 1 Joint Angle UPK51L-CRTSKA 0°41' +/-0°60' (0.68° +/-1.00°) UPK51L-PSTSKA 0°41' +/-0°60' (0.68° +/-1.00°) USK51L-CRTLKA 0°41' +/-0°60' (0.68° +/-1.00°) USK51L-CRTLKA*1 USK51L-CRTSKA 0°41' +/-0°60' (0.68° +/-1.00°) USK51L-CRTSKA*1 USK51L-CRTSKA*2 USK51L-CRTSKA*3 0°41' +/-0°60' (0.68° +/-1.00°) USK51L-PSTLKA 0°41' +/-0°60' (0.68° +/-1.00°) USK51L-PSTLKA*1 USK51L-PSTSKA 0°41' +/-0°60' (0.68° +/-1.00°) USK51L-PSTSKA*1 USK51L-PSTSKA*2 USK51L-PSTZKA 0°41' +/-0°60' (0.68° +/-1.00°) USK51L-PSTZKA*1 0°41' +/-0°60' (0.68° +/-1.00°) USK52L-CHTSKA 0°58' +/-0°60' (0.97° +/-1.00°) USK52L-CHTSKA*1 0°57' +/-0°60' (0.96° +/-1.00°) *1: includes Off road package *2: includes Sports package *3: includes YOUTH Edition package If the measured angle is not within the specification, adjust it with the bearing washer (See "Adjust Propeller Shaft Angle").

If the propeller shaft angle is outside the specification or there is vibration and noise, perform the propeller shaft adjustment using the following procedure.

(a) Adjust the No. 1, No. 2 and No. 3 joint angle.

(1) Support the propeller shaft with a jack.

(2) Remove the 2 center bearing mounting bolts.

(3) Slowly lower the jack, and disconnect the center bearing.
