pmclay Posted August 11, 2010 Share Posted August 11, 2010 My lx 470 makes a thunk sound when stopping then starting. Has anyone had this problem and do they know the fix for it ? the dealer has checked the drivetrain and says it is ok Quote Link to comment Share on other sites More sharing options...
mkupchyk Posted August 12, 2010 Share Posted August 12, 2010 Sounds like the famous "Clunk" issue. Toyota actually issued a TSB (technical service bulletin) for it back in 2006, but then updated it in 2008. It basically involves the dealer replacing the drive shaft. Now I think there is a new propeller shaft assembly. This was for the GX 470, but I am pretty sure other models like the LX, RX and a few others experience the same thing. People were saying that if you have less than 70K (?) the dealer does it for free. For a temporary solution (if that is what this problem is), you can try greasing the drive shaft, a lot of people reported that the problem then goes away for 3K - 10K miles depending. Here is a link showing the lube points. http://www.4x4wire.com/toyota/maintenance/front_end/lube/ Look at the bottom of this page, there is a good explanation about possible Clunk causes. I am attaching the TSB I found for the Clunk, & also another one about vibration.
