Update on Slip Yoke TSB
My dealer's service manager called (as promised) to advise me that they had a replacement driveshaft for my '21 GX. No more clunk noise upon initial acceleration. There was no visible difference in the part, just a revised part number. Speculation is that there may have been some slight change in machining tolerances? In any case, if you have a '16 -'21 (22?) with a clunk, give your dealer a call.
So I now have experienced the slip yoke thump/clunk on my '21 GX. "11,000 miles ) Have had it on my two '16 GX's. Easy fix---grease the slip yoke. Never heard clunks again.
Based on the latest TSB for 2019-2021GX's Acrad posted above, Toyota states "Do NOT grease/lubricate the propeller shaft slip yoke". Told dealer that their master mechanic had recommended and done that on both of my '16s. Says he contacted Toyota who advised him NOT to lube. He filed some kind of inquiry with Lexus and is waiting to hear back. What the heck is the difference on the19 to 21's?? This TSB has been out for over a year now, and no known fix? (BTW, this my only b*tch with any of my three GX 460's)

Just greased mine this weekend. I put the car in neutral and slid under there to do the work. Not a lot of clearance but since it was in neutral I could grab the driveshaft and rotate as necessary to get at the zerks. The car moves back and forth as you turn it so it's a bit of effort but doable.
Next time I'll put it on some sections of 2x6 or something to gain a little height. Beats taking the time to put it up on stands.

Thanks acrad for the tsb. I printed it out and just gave it to the service advisor. He said that helped, which is surprising since they usually don't like being given stuff like that.

I'm done with leaking grease guns. If you're able to share where you bought the empty lube shuttle cartridges so I can load my own grease I'm gonna pick one up for the driveshaft. I went to go use mine today and ended up with more on me than in the driveshaft, such a disaster.

So I put mine on jackstands so that I could freely rotate the driveshafts without worrying about my car crushing me. For each Zirk there is an angle that makes it easier to get to . I a just do this at the same time is a Tire rotation, so it's not really extra work.
I was able to grease everything with either the regular lock and lube coupler, or the right angle lock n lube adapter (not the super low profile one, just regular). Recently picked up an electric grease gun and it made the whole thing a lot more pleasant.

For accessing the grease fittings on u-joints a grease needle is the ideal tool.
Just depress the spring loaded ball in the grease fitting with the end of the needle and pump in the grease

Okay, garage report from me. I did this last night and it took me maybe 15 minutes max. I jacked up my GX and then put it in neutral. The only place where you have to slide deep under your truck is for the drive shaft behind the center differential, three zerks. For the other three zerks in front of the center differential, you just have to stick your head and arms in and it's very, very easy to reach the zerks if you use
, unless of course the zerks are pointing towards the passenger side. In that case, you'll have to slide under a little deeper. There's no need to remove anything. The quick disconnect tip of the LockNLube linked above is the perfect size (length and width) to reach the zerk fittings. Thank you, by the way, to those who recommended it. I can't imagine a better grease gun for our trucks, to be honest. Also, last but not least, the 8-10 for the slip yoke, I used 10. The 4-6 for the spider U-joints, I used 6. It was exactly at 6 when I heard the crack. Not much old grease came out. I saw the tiniest amount squeeze through which I cleaned using a wooden bbq stick with a shop towel at the tip, creating a long garage Q-tip version.
Considering that my GX is a '22 and only 2 years old (only 32,000 miles), the 'thunk' when going from 'P' to 'D' or 'R' to 'D' was not at all loud, but that sound and the way it jerked was noticeable enough. After performing the above, I drove it around for maybe 6 miles total, parking, stopping, etc. and I can't believe how all of that went away. The foward thurst/jerk also softened by a LOT! It's barely even there anymore. I would dare say that if your truck is brand new, way before this maintenance is required, if you feel the same thing going into 'D', grease your drive shaft. Perhaps you won't need 8-10 for the slip yoke or 4-6 for the U-joints, but it does help.

. Please go under your SUV one more time and take few pics of all zerks for the community. It is mandatory
