Fixing the Infamous 'GX Driveline Clunk' at Red Lights
A very common complaint among GX 460 owners is a noticeable bump or clunk from underneath the vehicle right after coming to a complete stop or when letting off the brake. This is caused by binding in the unlubricated propeller shaft slip yokes. Lube all 6 grease zerks (spider joints and slip yokes) with NLGI No. 2 lithium chassis grease every 10,000 miles. For slip yokes, pump until the yoke just starts to expand—do not over-grease to avoid hydraulic lock.
8.2 Quarts Oil Capacity: Don't Starve the 1UR V8
The 1UR-FE 4.6L V8 requires a massive 8.2 US quarts (7.8 liters) of 0W-20 oil with a filter change. Quick-lube shops frequently dump only 5 or 6 quarts in, leaving the engine severely underfilled. Always confirm oil level sits exactly between the dipstick marks after running the engine for 5 minutes and letting it settle for 5 minutes.
Front Differential 10mm Hex Drain Plug Warning
The front differential drain plug uses an internal 10mm hex socket. Factory torque is a hefty 48 ft-lb. Road grit accumulates in the hex recess; always scrape out dirt and tap the 10mm hex bit fully into the bottom of the plug with a mallet before applying breaking torque. If the hex bit is not fully seated, it will strip the plug instantly!
