Hi guys.
I recently noticed a faint rattle, almost a cross between pinging and a CV joint noise, it's a kinda knuckly noise for lack of better words.
It is intermittent and only comes up once the motor is at operating temp. It makes the noise when turning left under throttle and also sometimes when moving straight forwards. Only faint, cant be heard above reasonable radio volume and there is no vibration. Now I'm driving around radio off listening for this noise all the time.
I have never heard it when turning right. I noticed it earlier among the CV joint noise but it has persisted after I replaced both the Cv's, The RH CV was gone but I replaced both. The transmission fluid is black, I have booked the tranny in for a flush and to have an oil cooler installed but i'm skeptical that new fluid will fix this noise. I'm worried it is the tranny as the noise sounds mechanical and comes up under load, it is not just some loose rattle in the engine bay.
The TL has done 171XXX km's.
Anyone have any idea what it may be?. One tranny specialist said that they sometimes have a loose nut that rattles on another part in the transmission and needs to be urgently addressed before the tranny blows! I just had a look at a lot of threads but can't find anything similar.
