Drivetrain Backlash - 34r

[No Crust Racing]

When driving the car to work this morning I note it has some backlash in the drivetrain, coming off/on throttle. I can't tell if it's the clutch, box or diff. There's definitely noticeable noise when operating the clutch (ATS twin plate carbon) even when sitting idle with box in neutral, but there's also a little backlash when coming off on throttle or between gears. Thoughts?

I also hear about the transfer case being a culprit but to me it sounds/feels more central.

Car has done 86 or so k's, but it's a GT-R so assume 186 in terms of wear lol

Check the tail shaft.

For? Worn centre bearing?

Bearing would be a good place to start. Check all mounts ect.

All the usual suspects. The CVs are where all my backlash is hiding at the moment.

Just keep driving it till something breaks. Then you'll know EXACTLY what it is.

Well there's always that...

Hey Dan,

Did you figure out what it was? I'm having the exact same problem.. Feels as though mine is coming from the rear left though.. Same on/off throttle clunk

Neg, haven't had the time to work on either of the cars.
