Hey Guys seeking out some help after I have been noticing this annoying rattling noise when engaging drive or reverse while my engine is cold on my 2000 2wd 3.9l kota with 169,xxx. It seems to be coming from the front end of the truck but i cant figure out where exactly its coming from. it's shifting fine and engaging into gear. the noise goes away after the engine has warmed up and isn't found when its in park or natural. Awhile ago the belt tensioner went bad and I changed that and shortly after this pretty annoying rattling noise started to happen could it be related??? If anyone has an idea of what to check i would appreciate it. Thanks in advance guys!!!
