Strange noise on decel
Hello Everyone,
After doing some searching on here for the past month I've decided to create a new thread as opposed to bumping one that is super old. I want to start off by saying that my car drives great and the only issue I've had as far as the tranny is that third gear is a bit notchy (just seems to be the shifter more than anything). My real issue is that when I'm in 5th gear and I let off the throttle I can hear a grinding noise. It only happens on decel, when I coast downhill in 5th gear the noise tends to become more pronounced. I've only had the car for a little over a month. Its been driving fine and none of the gears grind when shifting.
I just wondered if anybody else experienced this sort of noise upon decel in 5th and if anybody could give me any insight as to what might be the cause. The closest thing I can equate the sound to would be a coffee grinder. I tried to get a video of the noise, but between the exhaust and road noise, I couldn't hear it on the vid. Thanks for any insight that can be provided.

I've seen vids of the tcase death whine and I've ruled that out...

Mine sounds like the exact same issue, except mine does it in almost every gear. Mine's coming from the front d/s right exactly where the tranny is...The fluid is at the perfect level, is super clear, and the trans and fluid has prob less than 4k on the Bushwacker rebuild so I want to rule it out but it is proportionate to the rpm NOT speed (like with a bad t case or wheel bearing would be) so I'm pretty convinced it's my trans. I'm going to change the fluid, I doubt that will do anything but can't hurt and like you I also just got the car and have had it for going on a month.
I would say it's something inside with too much endplay, and the noise is a bad bearing or something, and when it goes on the coast side of the gear the bearing that normally isn't loaded (since it's a helical gearset) now has some pressure on it but I really don't know. I've read the input bearings suck and wear out alot but I would think Dan would have noticed anything wrong with the trans when he had the trans apart so I almost don't know what to think but deff let me know if you find out anything too

^^thanks for the insight bud as it makes a lot of sense. I'll let you know if I come across anything, I've been searching for about three weeks.
I'll keep bumping the thread until somebody can give us some answers haha

Maybe I missed it but do you have an aftermarket clutch and or flywheel? If so, this is a VERY common issue/noise it makes.
Tell me this, if you take the car out of gear and coast, it doesn't make the sound anymore does it? It's only if it's in gear, correct? If so, it's normal from what I've researched.
