Car Forum / Nissan / Nissan Cars / April 2006frontier 2006 LE "clang"
nissan frontier 2006 LE metallic clang sound is heard after car intially started, hot or warm and gears change from 1st to 2nd, sound occurs very loud if engine has been off for 8 hours, less if engine off just a few minutes after that, for the rest of drive, no sound, no matter how many stops as long as engine stays on anyone know what this might be, dealer repair shop is baffled and just want to keep car but have no solution the sound happens *after* the shift from 1st to 2nd, within 10 seconds Its probably a loose heat shield on the exhaust. More annoying than a problem. > the sound happens *after* the shift from 1st to 2nd, within 10 seconds And it's still on warantee. > Its probably a loose heat shield on the exhaust.

If it is indeed the driveplate (also called flexplate), eventually it'll make noise continually until the bolts fall out and you won't be able to drive it at all. Not sure about a frontier, but there's usually an inspection hole at the top of the engine/tranny where one can inspect (also loosen/tighten) those bolts by turning the manually engine with a wrench.

The guys in that service department would most likely know how to do that as it is something they usually do to remove an engine. You basically turn the engine manually by putting a big wrench on the crank pulley. When you slowly turn that wrench, while looking into that inspection hole, you will come across the bolts that hold the drive plate to the torque converter. Ask them to make sure those bolts are properly torqued down. If the driveplate and torque converter are not properly attached, you will hear random clanging noises. There are also bolts that hold the drive plate to the crank shaft, but that those are loose is less likely (there are many of them) - one will also need to separate the engine from the transmission to get to them, which is obviously a lot more work.
