Drive shaft replaced with drive shaft with from GX470?

[hobosapien]

I have read a few threads that people have done this to eliminate the 'clunk' when putting the 4R into drive (I have gotten this a few times and it scared me to death).

What's the part number for the shaft? I want to replace mine and eliminate any reliability issues in the future (as well as greasing).

Keep it greased every now and then and it won't clunk.

My gx470 has the same clunk so not a garenteed fix. Six zerks require grease every 7500 miles. Just get under there and lube it.

I guess this would be the cheaper route! Are there instructions for how to do this? I suspect mine haven't been greased in some time.

Mine doesn't respond to zerking it for more than a couple days. Was planning on the gx swap as I believe it's 'sealed' enough it doesn't need constant lube.

Doing the 5th gen brake upgrade first to ensure the clunk isn't the calipers sticking.

You need to make sure you use the right kind of grease. I find the stuff that works the best is this:

Green Grease | The Best Grease Money Can Buy!

My local Autozone had it. Easy DIY job.

I use Mobil 1 synth like most others here. What makes green any better or was that just a general recommendation?

I think I use Lucas red and tacky.

A marine grade bearing / axle grease would work great too.

I tried a couple different types of grease before switching to the green stuff and none of it worked as well to get rid of the stop light "clunk". Just one data point...

I had the clunk, scared the sh*t out of the first couple times, I used the green grease about a month ago and no clunks since.

I was able to only find 3 out of the 6 zerks, mind you I had very little room doing this on my garage floor. Next time I get that chance to put it up on the lift I will grease all 6

As an engineer, I loathe anecdotal evidence. Until it comes to my 4runner. Almost always rely on it ha. Seriously, I'll prob pick up a tube and try it. Beats $300 on the new drive shaft.

 

[Morphyne]

I've always used green grease. Never had a problem.

Lube it good and the clunk will go away. I always use Lucas red and tacky grease. Does the trick. No more clunk.

Toyota actually specs two different greases for the drive shafts...one for the U-joints and another for the slip yokes. Check your manual, it's in there.

Personally, I've been using Valvoline Durablend for both. The U-joint probably doesn't need to be hit every oil change..I usually see joint expansion with only 2-3 pumps from the gun. The axle wrap thump seems to come from the slip yoke binding, which can take 20+ pumps from the gun before you see the joint expand.

Lots of folks complain the thump is a design defect or such b/c Lexus updated the GX shaft in response to complaints, but driveshaft lubrication is a documented maintenance item in the 4Runner manual...at least for my 2003, so it's not like Toyota tried to pull a fast one on us. And if we don't believe in lifetime lubricants (WS ATF, diffs, xfer case), why would we trust the "liftetime" grease in a sealed slip yoke?

I remember seeing somewhere that Toyota updated the service manual for the use of only one (I could be wrong).

I also remember seeing that the Mobile1 synthetic grease (pink stuff) meets or exceeds the requirement for the grease, which is why most use it.
