Lexus LS460 AWD Front Drive Shaft Assembly 37140-50010

This is a complete front drive shaft for the all-wheel-drive Lexus LS. It fits the 2009-2017 LS460 AWD with the 4.6L V8 and the 2008-2016 LS600h hybrid with the 5.0L V8. It replaces Toyota/Lexus 37140-50010 and crosses to Dorman 938-389. Rear-wheel-drive LS460 models do not have a front drive shaft.

The shaft is steel and runs from the transfer case to the front differential. It measures 29.06 in. extended and 27.24 in. compressed, end to end.

A worn front shaft on these cars usually shows up as a vibration or hum that comes in at a certain speed, a clunk when you take off or shift between Drive and Reverse, or a joint that feels rough or loose when you rotate the shaft by hand with the car safely supported. A torn boot that has thrown grease on nearby parts is another sign. Check the engine and transmission mounts too, because a broken mount can cause a similar vibration.

When you install it, clean the flange faces at both ends, replace any damaged bolts, and torque them to the factory spec. Check the front differential and transfer case output seals for leaks while the shaft is out.
