I'm chasing down a gear whine type noise in my drivetrain that happens between 40-60 mph but it only happens when the drivetrain barely has a load applied to it.
Whine will come in for a split second when letting off the throttle to shift from 4th to 5th right when the drivetrain goes from loaded to unloaded. If your cruising along in 5th and just barley giving it throttle, like 15% throttle angle I get whine. The second more throttle is given or I let off the throttle he whine goes away. If I push the clutch in whine goes away. Rear end backlash, preload and all that stuff have been checked and double checked.
Was under the car this weekend trying to figure out what's causing this and think my whine might be the drive shaft rear CV joint. The CV joint feels loose and when I grab the end and push on it I can get it to move back and forth around 1/16", uploaded a youtube vid showing the movement.
I'm not a CV joint expert but does this joint seem bad to yall?
Edit: You can hear the clicking/movement if you have sound on.
