Diff Noises

[Nero]

Hi All

Just recently bought a R33 GTR and have noticed some noises coming from the diff.

At first thought the noise was a loose exhaust as it sounds like something rattling. The noise is mainly happening up and down driveways or taking off on an uneven road any help would be great.

If you do a really tight turn at low speeds, like a u turn, does it happen heaps?

Has this just started or has it always made that nouse?

Its always been there but was under the impression it was the exhaust it make that noise yes when doing a u turn inside wheel feels like it is locking as well

Sounds like you got a locked diff there mate, i have one on my GTR those noises and the inside wheel locking when turning is normal.

Nero I'm sure you could find someone to take it off your hands/swap for a standard one if its a problem

[Nero]

Thanks mate just concerned if diff was ok what are the advantages or disadvantages of the locked diff

[Adam_54]

Better traction, good for drags and a disadvantage is your tires wear out faster.

[Duncan]

and the downside is the noise you have noticed

If you can live with the noise they make an amazing difference to how your car can put power down out of tight corners

Thanks guys for all your help considering i am planning on taking her on a few track days next year iam not going to complain.

A locked diff increases tyre wear significantly, moreso of a problem if you have excessive neg camber. Also creates a bit of understeer when you're not putting enough power to the ground, and can increase the stress on the rear driveshafts. But it will stop open wheel spinning and evenly distribute power to both wheels.

If you can put up with the increased tyre wear, skipping at low speeds, and increased noise, I don't think you'll have a problem

What about those diffs that are have adjustable diffs made by Nizmo? Exactly how can they be adjusted, will it eliminate the skipping of the wheels at slow tight corners? It would be nice to maintain factory manners for daily driving.
