Link to the actual TSB

I heard that the Driveshaft/Propeller shaft is covered under the 70k powertrain warranty, but the Suspension Control Arms are not. I am unsure if that is really true & people that had the fix did not report being charged for the arms. (I think the labor for everything would be covered, but maybe only some of the parts.)

Where is the actual TSB, I coluld not find it.

I am also hearing the same clunk on my 2007 GX470 since i have it and now it has 7k miles.
I will ask the Dealer at the next oil change to look at it but need something to backup my claim...

My dealer replaced both the propeller shaft as well as the control arms on my 08 GX470 @ around 3000 miles. I had this problem on my 04 GX so I knew exactly what the problem was on the 08 when it started happening. I was surprised that it started happening so early on the 08... The 04 had at least 30k miles (maybe 40k) on it before the clunk started happening. On both vehicles the TSB fixed the problem with no recurrence.

I've looked all over for the actual copy of the "clunk" TSB. I can't seem to find it. Does anyone have the actual TSB? I've already tried the forum and Google search on the new TSB #L-SB-0116-08 and DL001-06. It seems to keep going around in circles with no actual document. I have an appointment to take my truck in on Friday and I'd like to have the documentation. Thanks!

Try the pinned topic on top of the GX forum. I have the TSB write-up on page 9 (since this topic has been fully discussed numerous times) but I'm not sure if it's the same or different TSB number compared to the one written on the first page of this thread.

What exactly is “the clunk”? I read a good portion of the pinned post on the issue but I can’t seem to find what it is and when it happens.

I have an 07 so I’m guessing that it isn’t an issue with this model year.

One thing I do experience is this. As I slowly pull up to a stop sign or red light and just before the vehicle comes to a complete stop it feels like something releases. The truck kind of lets go of something like the transmission is going into neutral.

I don’t hear a clunk so I’m assuming it’s something else.

Unfortunately, the clunk affects 2003- 2007 AND, even the 2008, as I have come to learn. The Clunk is felt when you are slowing down or when you come to a stop, 1-2 seconds later, you feel a lovetap or a slight "clunk" from the rear. There's a technical service bulletin for this from Lexus and they will change the driveshaft and control arms for 2003-2007. As far as I know, it's just an annoyance and no safety implications.

can you get the drive train replaced even if you arent experiencing the clunk? i.e. can you tell them it happens intermittently?

The dealer is suppose to verify the problem b 4 they fix it, but sometimes they dont because the its such a common problem in the GX, but you know the saying " if its not broken, dont fix it" it may cause more problem.
