hey everyone im new to the forum and have a question about my 2001 ram 1500.

Ive been having a whinning noise coming from my truck for a few weeks now and it needs to be resolved. the noise is noticable from around 20 mph and gets worse up until 65 or 70 mph and goes quite. it is loudest when there is higher load on the truck and when stepping on the accelerator and noise reduces when coasting. it happens on all road surfaces during all conditions.

any help would be greatly appriciated. thanks
