Acura RL. Manual - part 353

Use a thicker 25 mm thrust shim to move the transfer hypoid drive gear away from the transfer 
output shaft (hypoid gear). 

Flank contact must be adjusted within the limits of the transfer gear backlash. If the backlash 
exceeds the limits, adjust as described under Heel Contact. 



Face Contact 

Use a thinner 25 mm thrust shim to move the transfer hypoid drive gear toward the transfer output 
shaft (hypoid gear). 

Face contact must be adjusted within the limits of the transfer gear backlash. If the backlash 
exceeds the limits, adjust as described under Toe Contact.
