greasing drive shaft

[Bonniem]

Hi guy, I was greasing my drive shaft yesterday and by mistake pumped a lot more into FWD Slip Yoke zerk instead of spider joint . Was kind dark when I did it. I removed the zerk to see if anything extra will come out but nothing. I drove it and did not notice any vibration or something unusual. Should I stay with the way it is or there is something else I can do to prevent any further damage.
Thanks

It's fine.

You can remove the zerk and bounce your runner up and down front to back violently, clean up anything that came out and put the zerk back in.

You want that slip joint to be able to move freely and not locked with grease. I doubt you did that and its debatable whether it's even possible, but peace of mind is nice. Here is a good animation that shows how it works basically.

I used the grease on my 2016 runner .. july 2016 greased it on the slip yoke and u joints .... did it greased every year in the fall ...
moly grease is the slip yoke and the u joints lithium grease.
I pumped the 3-4 and the grease is out the seal .. then clean it ..
no issues looks good

Maybe you right, I can run it with a zerk off through a few bump stops to see if I’ll loose any grease.

you might be over thinking it. I think they come from the factory under greased. First time i greased my shaft, i pumped an insane amount of grease in there, nothing came out of the zerks when i thought i over did it. My drivetrain hasn't exploded yet.

Now, i just do a few pumps once a year and be done with it.

You'll be fine.

I always pump grease into the slip joint until it starts moving. I do this at every oil change (every 5000 miles) and have never had any problems. In my opinion you need to have enough grease in there to keep the slip joint properly lubricated, and since the seal allows grease to escape means the grease lock issue is a non-issue.

There is seal cap on the end of the yoke and it will pop out if there is way too much grease to escape slowly trough dust seal on the shaft.

Toyota recommend every 15000 but I missed my at 15000 and I’m at 31000 right now.

Not saying that can't happen but the situation in that thread sounds like grease was so gunked up that it couldn't get past the dust seal so the popping seal cap was the only escape. Probably from a lack of regular servicing.
