The big question is.......

[TRZ06]

Did they fix that driveline clunk with the new design

 

[dwulffusa]

My guess is yes. This only really affected V8s anyway. (Though I get it in my V6 in 2WD after decelarating sharply to a stop, it thunks when I release the brake and roll fwd). The 2010 SR5 and Limited I have driven did not have this issue, though everything is just right when cars are brand new so who knows.

I doubt it. I have the clunk in both my '05 Taco and 4Runner. It did not clunk when it was brand new, started after a year or so.

IIRC the underpinnings of the 5th gen are a carry over from the 4th.

:iagree:

I suspect the 5th gen Limited owners will be the first to complain. The dreaded thump seems to affect the V8 guys the most (no 2wd drive mode). The only time I have ever noticed a hint of it is in 4hi.

I think with the fact most 5th gens, for now anyways, will be run in 2wd most of the time it won't be as much of an issue...

We have a limited with around 600 miles and have yet to feel a clunk. We have also spent about 80 of those miles with the 4hi locked due to a blizzard here. My '08 Tundra on the other hand...

Another positive is that Toyota KNOWS how to fix it since they did it in the later model GX470. (It does prove just how cheap Toyota is because they did not fix this issue on the later 4th gen 4runners from factory!) So, hopefully, with a REDESIGN, Toyota should have eliminated this problem.

What is the actual fix that Lexus preforms on the driveshaft that Toyota doesn't?

I'm tempted to take it right off, and clean up both the female and male splines to try and fix it. Lubing it up only fixes the problem for a month or 2 then it comes back.

The Lexus TSB involves replacing the control arms also in addition to the driveshaft. In other words, it is a suspension design issue, not just a driveshaft problem.

I take it when Lexus changes the control arms, it changes the rear suspension geometry in some way.

Does anybody with a lifted 4th gen notice an increase or a decrease in the driveshaft clunk?

 

[03_4x4Runner]

I have never had the clunk in my 03 V8 4x4 when stock or after the lift. I grease the driveshafts every 5k miles.

There is a new Lexus TSB for this issue L-SB-0116-08 that was put out Sept 17, 2008. It only involves changing our rear propeller shaft frpm 37110-6A480 (same for 4runner V8 4x4 and Lexus GX) to 37110-60A40. The fact that Toyota has had a TSB out for Lexus from 2003 to 2008 models means they are slow to learn and adapt much like the current gas pedel problems. If they knew about the problem why not do a production change to the new shaft? $$$ is my guess. Anyways once my 4runner is gone (hope it lasts a long time) my $$$ will be going elsewhere.

I am not sure if that is correct… My 96 had that thump only in 2wd mode and never in 4wd..
However, I did had that thump in my 2005 with V8, but it was very infrequent, I would say 1 in 20 stops.. Interesting part is that now thump is completely gone after my very minor spacers lift.:thumb3:

Well once more I will disagree and convey my experience. My driveshaft (only) was replaced about three years ago, and still no clunk. All I do is shoot a little Mobile 1 grease in it periodically. (Yes, I know, specs call for some other "official" grease. yadda yadda yadda):thumb3:

its not that they are slow to learn and adapt. It has something to do with their work ethic. If one person says something, either people look at him funny or reject him. If the whole group says something, then collectively this is more acceptable and something will be done. (this was put as simple as i could make it). I read about this on the issue of gas pedal recall and decline of japanese quality. Sucks if one engineer sees design flaw and the other 9 dont!
