Experience with GX470 Driveshaft Swap

Hello,

I have a 2007 V8 T4R, and of course it clunks when stopping. It's annoying. I've done some research on the forum here, and it sounds like the GX470 driveshaft (part number 37110-60A40) solves this issue, since it is a sealed part.

I could only find 1 person on the forum (skyak) who did this swap back in 2011, and he posted a few updates with good results, but stopped doing so after 8 months.

Has anyone else performed this swap? If so, how has your experience with been long-term?

Thanks,
Robert Abuey

Clunk is an easy fix. Get a grease gun and put 50 pumps into the slip yoke until you start to see the slip yoke move back some. Don't stop right away keep pumping until it moves some more.

Usually this fixes the clunk.

I would do this before getting a new driveshaft.
 
There is actually a TSB for the 4th gen 4Runner now too, but they wont replace it unless your under warranty. Yes, that driveshaft definitely helps with the clunk.

I remember reading quite a bit more threads (maybe Ih8mud or the 120 forum?) that this seems to fix the problem. It is a straight swap into the 4R. Seemed to solve most issues on the GX side of the table and should fix yours as well but sometimes you never know with these vehicles.
 
i get it on my 2WD V8 too... every now and then after a complete stop it clunks .... bugs the crap out of me. do i have to get a GX 2WD shaft for a fix?
 
so can you grease these updated drive shafts or are they completely sealed? do they have any grease fittings?

That's the transmission with its Camry-driver targeted shift pattern not keeping up on a stop. It's still in 2nd, with the 1st gear shift solenoid energized. But the transmission has to slightly move to complete the shift.

If you inch forward at a stop light you'll hear it audibly clunk into 1st.


It's pretty annoying, as driving in rush hour Houston traffic frequently gets me in a situation where it's be stuck in 2nd like this.
 
I have been fighting this problem for awhile on my 08 4wd Limited. I actually had a Toyota dealer tell me to lube the driveshaft yoke with a grease from the Ford dealership. It is Motorcraft XG-8 PTFE grease. So far it is the only grease that gets rid of the clunk for any length of time. Every tire rotation, I raise the truck and let the rear axle hang so that the tension is completely off the driveshaft yoke. Then I fill it full of the blue grease. Works great. But I think I will eventually swap out the driveshaft to the one-piece version from the GX. And no, from my understanding, the GX driveshaft has no yoke, so no need for grease

Driveshaft

I decided to go ahead and swap out my drive shaft for the updated part number in the TSB. Got it from Boch and received it a little over a week later(MA to CO). The drive shaft I received part number 37110-60A40 does in fact have a slip yoke and a grease zerk for it. I went to put it on this last Saturday and I was unable to loosen any of the bolts. I tried an impact gun, but it's only my little pancake compressor running it. I'm betting a combination of penetrating oil, heat, and a decent impact setup would do the trick.

Since the clunk was driving me nuts every time I decided to grease everything. I've done this twice recently. The first time it didn't remove the clunk. The second time I greased more aggressively and it went away for about 50 miles. So this being the third time I decided to grease the front shaft yoke until I could see grease coming out of the yoke interface. It took quite a few pumps, but it pushed out a bunch of old grease and gunk. My clunk is gone and has been for well over 50 miles. It did seem in the cab that the clunk was coming from the front, but after reading about everyone having issues in the rear I assumed it was the culprit. I still plan to install the new drive shaft as I already bought the dang thing.

Update

While having my suspension replaced the tech went ahead and changed out my driveshaft for free (Addicted Offroad). Those guys really are pretty nice to work with. The updated drive shaft has yet to clunk once, so I'm really glad I bought it now. Shortly after my post above, the clunk came back. It did infact turn out to be the rear shaft. I was only greasing the front initially to rule it out as the culprit.
 
does the new drive shaft still have to be lubed? does it have zerk fittings in all the same places as the old one?

I believe the drive shaft will still need periodic lubing. It has the same zerks as my previous drive shaft with one for the slip joint, and one for each u joint. I posted a couple of pics a few posts back in this thread.
 
Update

After a couple of months I have still yet to feel a clunk. So for those who are sick of constant lubing or who couldn't get their clunk to go away with lubing I think this is the best option. For 285 bucks it's not a cheap part, but that clunk was so annoying it was worth it. I couldn't even enjoy driving the truck as I was always anticipating the clunk.

awesome to know, thanks for the followup. BTW your pics from previous posts aren't available anymore, chances you can re-post?
