How does the slip yoke work on a Lexus GX470?
The height changes more, so does the driveshaft. The driveshaft has a slip fitting (called the slip yoke) that allows this length change. There is a grease fitting designed to allow lubricate the plunging and extending motion, but even with sufficient grease the motion can stick.
Why does my Lexus LX470 thump when I stop?
The 1998-2007 LX470 and 2003-2008 GX470 both had variable height control systems ( hydraulic for the LX470, air suspension for the GX470) that share a common problem: a thump, clunk or “kick from behind” when coming to stop or taking off from a stop. The issue most commonly is from the rear driveshaft.
Where does the power come from in a Lexus GX470?
This driveshaft passes power from the transfer case underneath the vehicle to the rear differential, which then splits the power to both rear wheels.
Why does the LX470 need a driveshaft change?
While a driveshaft changing length is a required feature of vehicle with a live rear axle (the length change accommodates the suspension movement of the rear differential so the driveshaft doesn’t explode the first time you hit a bump), the GX470 and LX470 driveshaft requires more extension from the driveshaft due to the height control system.

Why does my Lexus LX470 clunk from a stop?
The grease fitting is highlighted. The grease would have helped prevent the binding, but not in all cases. Fortunately for the GX470 and LX470, Lexus has updated the rear driveshaft to help prevent this issue reoccurring, but periodic greasing of the driveshaft’s bearings and slip yoke is crucial to perform regardless.
