Since I am taking my car in for inspection regarding the Belt Tensioner and Drive Belt under the 100K. Can I ask them to check my lift bolt and have it replaced if needs be?
Also, does the timing chain wear out?
the timing chain is almost never changed in a car's lifetime unless there is a problem with it...i honestly wouldn't worry about it as long as everything is kept well oiled.
and yes, you can get your dealer to do it for you..as i said since it's a TSB it's covered under warranty for 60,000 miles (if you bought a certified used car with a manufacturer's extended warrany to 100,000 miles is NOT applicable--only 60,000 miles applies for TSB's).
so, if your car is still under 60,000 then you can get them to do it--if it's not i would just do it myself. it really wasn't hard at all. just go to your toyota dealer and ask for the part # mentioned in the link i posted above for the lift bolts
