I had the driveshaft replaced and so far after some testing of hard stops, etc......NO THUMP! Here is the TSB info: TSB DL001-04 Rear Driveshaft Clunk Noise. According to the Tech that worked on my car, Lexus redesigned the driveshaft and coated the splines with Teflon. We'll see if this is the final chapter.

Although I don't think I experience this but can I take it to the dealer and have them implment this TSB on my GX anyway? I know someone may say this. How can we fix something that's not broken? In other words, we should be able to change the part before it can potentially be a problem. Does it make sense?
Or am I far off in left field?

well it depends when ur GX was built. i think it only applies to certain GX470s, like 03s and some 04s. I think. don't hold me accountable for it but that's what i think i've heard. haven't done it yet for mine. still thinking about it.
