Chassis Lubrication / Grease - Propeller Shaft / Spiders & Slide Yoke / Zerks
I didn't really see a thread on this so will start one. I plan to do this when I service the diffs and TC a few weekends out. Lots of other threads on other Toyota sites. I assume things are very similar to any of the torsen diff based /AWD 4Runners models.
Owner's manual says this: https://cimg4.ibsrv.net/gimg/www.clu...d0dfb78090.png I need to crawl under and look or check FSM. Zerks (1) Front Slide Yoke (1) Rear Slide Yoke (2) Up front one for each u-joint/spider (2) Two each u-joint/spider in rear S - Y -S (Transfer Case) S - Y - S REAR DIFF <-> U-Joint/Spider <-> Rear Slide Yoke <-> U-Joint/Spider <-> TRANSFER CASE <-> U-Joint/Spider <-> Front Slide Yoke <-> U-Joint/Spider <-> FRONT DIFF I will be using these Amsoil products: Synthetic Multi-Purpose Grease NLGI #2 https://cimg4.ibsrv.net/gimg/www.clu...bf762dc95c.jpg EDIT: Removed Amsoil Slide Yoke option... they don't have a recommendation. I might be going OEM on this as well. FRONT https://cimg7.ibsrv.net/gimg/www.clu...d98b5e2045.png REAR https://cimg1.ibsrv.net/gimg/www.clu...523fa617fc.png |
Saw this promoted on Tundra forums as excellent option for the slide yokes and has moly in it as well. It sounds like you only want to put in 4-6 pumps on the slide yokes and steer clear of pumping grease until you see it ooze out.

Showed up today... might do some of this next weekend when I change all the brake pads.

Lubed the zerks today. Here is what you will actually find.
Zerks (1) Front Slide Yoke (1) Rear Slide Yoke (2) Up front one for each u-joint/spider (2) Two each u-joint/spider in rear S - Y -S (Transfer Case) S - Y - S There aren't two on u-joints in rear as I originally thought. Not sure what is included with Lexus 30K service but these zerks look factory virgin. I am doubtful previous owner received a Lexus service they paid for. Exactly a reason I like doing this myself... I really don't find car maintenance fun at all but I like know it is done right and saving a few $$$ never hurts either. |
Grease Fittings/Zerks
How often do you do grease the zerks in the GX 460 if you do only highway driving and no off roading?
|
Service guide lists 12 months / 10k miles or severe at 6 months / 5k miles
Of course the following is stated under severe as well for on-road https://cimg2.ibsrv.net/gimg/www.clu...595de81606.png Side note for off-roaders https://cimg4.ibsrv.net/gimg/www.clu...b642c50b01.png https://www.clublexus.com/forums/gx-...lide-yoke.html |
Thank you, I asked a dealer about it and they were not aware of grease fittings...made me wonder if they skip it for customers unless they ask specifically. I guess it's very rare now to have zerks in a vehicle.
|
As I stated in linked thread... all six looked like they had never been touched on mine.
|
That makes sense, i guess people who trust the dealer for complete service most likely never get this done as it is an overlooked item

Sadly "dealer service" is held up on a much misinformed pedastal. The techs can be shady and, like any time pressed human being, cut corners where they can get away with it. My rig has 52k on it so will be doing this service sometime in the summer. |
The chassis lubrication is even listed in the owners manual too... just want to make everyone aware of it.
On the yokes only like 10 pumps.. those you don't want to over-grease or it can create a vibration problem... you will find threads on 4R forums about it. |
How accurate is this drawing?

Can of worms.....
What would the issues be if we only used 1 type of grease? The chasis lubrication screenshot you posted shows Lithium NGLI #2 suitable for both the spiders and the slide yokes. I am assuming greasing everything will help with the transmission jolt/jerk during stop and go traffic? Currently 2nd start is used to help with slower stop and go city driving. |
From what I can tell both should be fine but the moly based grease may end up lasting longer if you let maintenance slip. Either grease though you just don't want to over grease the yokes as these are continually expanding and contracting as you drive.
From 4R forum: "When you over fill it, the grease takes up the space inside the driveshaft where the yoke is supposed to slide into. Air compresses, grease doesn't (easily), so it is now acting more like a solid driveshaft. " |
Acrad, thanks for posting. i actually started the process this past weekend. I was underneath (checking a different issue, the leaning) and saw the zerks lined up on the rear drive shaft so I went ahead and greased them with the valvoline synthetic grease (what several forums on the 100 series recommend). i did not over grease like it is recommended on the 100 series (to help with a “clunk” on most cruisers). I couldn’t believe it myself but it actually worked. From this I did learn that the shaft zerk (not the u joints) have an overflow so if you overfil them they will release grease so I don’t think a vibration would start from that. Def stick to a moly synthetic grease and you’ll be alright. Don’t think oem is necessary just don’t go with a non syn grease as they simply just don’t last a long time. the below is for the 100 series and only for FYI https://forum.ih8mud.com/threads/the...thread.401590/ |
