Joint Angle: Inspection

WARNING: This page is about a different car, the 2003 Lexus GS 430 and 2003 Lexus GS 300. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: When performing operations which Involve the removal and installation of the propeller shaft, always check the joint angle. Make adjustments if necessary.

STABILIZE PROPELLER SHAFT AND DIFFERENTIAL
1. Turn the propeller shaft several times by hand to stabilize the center support bearing and flexible couplings.

CHECK NO. 2 AND NO. 3 JOINT ANGLE
1. Using SST measure the installation angle of the intermediate shaft and propeller shaft.
  SST 09370-50010
  
  HINT:
  
  The SST should be directly underneath the tube.

2. Using SST, measure the installation angle of the differential.
  SST 09370-50010
  
  HINT:
  
  Measure the installation angle by placing the SST in the position, as shown in the illustration.

3. Calculate the No. 2 joint angle.
  No. 2 joint angle:
  
  A-B= -1°01' +/- 37'
  
  A: Intermediate shaft installation angle
  
  B: Propeller shaft installation angle
4. Calculate the No. 2 joint angle.
  No. 3 joint angle:
  
  B-C= 1°14'+/- 42'
  
  B: Propeller shaft installation angle
  
  C: Differential installation angle.
