Eliminating FJ Cruiser Stop Kick - Greasing the Spline
HTML-код
- Опубликовано: 26 авг 2024
- I had a common issue on my previous FJ Cruiser. I would get a "kick" after coming to a stop. It felt like someone had lightly run into me from behind, but that hadn't actually happened. Instead, I was afraid the transmission was failing. The mechanics checked the transmission indicating things were normal and I had the transmission oil changed, but it didn't go away.
Due to moving countries, I sold my first FJ and purchased another one and it had the exact same problem! I thought it was highly unlikely that they both had transmission issues (especially with less than 100k miles), so...
After some research, I learned that it was likely a severely under-greased rear drive shaft spline. If not greased well, the spline would stick inside the shaft then break loose causing the "kick" a few seconds after coming to a stop.
This video goes through the procedure I followed. I initially greased it a couple of weeks before this video and it greatly reduced the kick. I put a TON of grease in the spline until the grease started seeping out of the seal (as seen in the video). The spline was really tight, and the shaft was forced out several millimeters (not normal, but OK for this process). I returned today to check up on my handy work and put a little more grease in it. It is moving much more smoothly! It should now not need any more grease for a year.
I hope the comments above and this video helps someone with the same issue I experienced, and let me know in the comments!

Nearly hitting 200K miles on my FJ and I didn't know where all these grease points were, thanks!
Man that Texas undercarriage looks pristine. I'm in the north east and have a ton of surface rust. I'm watching you wipe away flung grease and thinking to myself, "nah man if you leave that grease it's free rust prevention" (which you obviously don't need).
found the grease fittings a few years ago and it eliminated the "stop Kick" as advertised. I contacted the local Toyota Service Center and told them about it, they didn't even know about all the grease fitting underneath the FJ. Great video!
Thanks Tank!
Nice effort taking care of these hidden parts of the car everyone else might skip.
I've had my FJ for a few months and was worried about the 'kick". Thanks for posting!!!
Years ago Toyota had a limited time recall on these drive shafts. The new drive shaft came with an upgraded slip yoke that eliminated the binding/bumped from behind problem. Part # 3711-35B00. Toyota replaced mine. The Service Manager told me I was the one he knew of to take advantage advantage of the free replacement.
Only?
37110-
Was not a recall was a TSB
Thanks! Just had my FJ greased up. Reminds me of helping my grandpa with his tractor and implements when I was a kid.
this fixed it! Thanks and god bless
Good tips!
I searched, "Greasing the Spline," and this was NOT what I was expecting.......wait, 5:27 was kiiind of what I was expecting.
My 2007 FJ Cruiser automatic 2WD doesn’t have any fittings for grease… WHY?
Question for you when I put it into reverse and first Gears only,it feels like a popped kick . Driving the pop kick goes away. Is this the pop kick you’re talking about ?? It just started doing this pop about a week ago ..
You over grease the spline and you essentially hydrolock your differential. 3 to 4 pumps max
Hry can you give more detail about this?
Spline or Slip yoke is for expanding and contracting the drive shaft when the vehicle pass over a hump, pothole etc. If we fill the tube with Grease, there won’t be space left for slip yoke to move inside. As an example, imagine a syringe filled with fluid and the press the plunger when needle adapter is closed with other hand.
@@migveb2184 you DID see the grease squeeze out right? That means it's not locked
I believe you are referring to a hydrolock in the spline shaft which may affect the bearing in the differential?
I've heard of this potential issue before, but did a fair amount of research before I decided to grease mine the way I did ("FJ Cruiser Forum" and "ih8mud Forum" each have a couple of threads on it as well.) I also have plenty of smooth up and down travel on the truck after the greasing. One of the Toyota service manuals (for an LX) apparently states to pump grease in until it passes by the seal.
I felt comfortable filling the spline with grease to push the old stiff grease out and replace it with new grease, and the kick is essentially gone. The old grease is the culprit, and tbelieve
off-roaddiff lock
@@migveb2184 ...bad analogy. Filling the tube with grease will DEFINITELY NOT prevent further movement.
Great info!
Thanx
What is the stop kick ? Please explain
Does this answer your question? "After some research, I learned that it was likely a severely under-greased rear drive shaft spline. If not greased well, the spline would stick inside the shaft then break loose causing the "kick" a few seconds after coming to a stop." It seems the rear driveshaft spline was machined too tightly by Toyota and would not allow enough grease to stay in place to prevent the issue without semi-regular greasing. The kick had come back after about 1.5 years and ~20k miles, but I greased it up again and it has gone away.
I just replaced the rear drive shaft $920 because of the kick.. dang what a waste of money
How many miles on your FJ?
As far I know, the drive shaft/u-joints are supposed to get greased at every oil change. If memory serve me right, there ought to be 6 of them.
Hi Michael. I recently purchased mine used with 120k miles on the clock. While the u-joints had evidence of being greased previously, the spline didn't look like it had ever been greased. My theory is with the motion of the spline in and out, it pulls air into the cavity through the grease zert. This is OK because the grease is still in the spline area where it is needed. However, if you just put a little grease in each time it will never fill up the cavity and force the grease through the spline, effectively never greasing the spline. Not sure on the suggested frequency of this service, but the grease should stay in place fairly consistently. I show in the video there are 6 grease zerts...4 u-joints and 2 splines.
I now have 130k miles on the truck and I had about 120k on it when I did the video. My old FJ had about 80k and it also experienced the kick, but I sold it before I discovered the remedy. I contacted the buyer to let him know how to fix it.
There are 6 grease zerks. 3 on the front shaft (2 u-joints, 1 spline), and 3 on the rear shaft (2 u-joints, 1 spline). The front spline zerk is quite difficult to get to if I remember correctly.
Not Sure that rear tire carrier is designed to sustain the bouncing weight of a grown man, but hey! Lol, thanks for the vid!
Too beautiful of a shirt to be greasing under an Fj with.
Has the stop/thunk came back? Is this a legit sustained remedy? I am very annoyed with mine at each stop. Thanks for the video.
I haven't experienced the kick again since the time I did the video. I've driven about 8000 miles since, so It likely needs a top-up.
What type of grease are you supposed to use?
