Diff ticking when turning going slowly in reverse

[Jim621]

Hi All,


Ive noticed that my diff in my AE86 clicks when reversing slowly while turning in a circle.
I presume this is some sort of locker in the diff that is letting the outside wheel spin faster, so the diff freewheels.

Do you know what type / brand of diff that would be in my 86 making this noise? my guess is a Detroit locker (although im not sure you can get detroits for an AE86?)



It’s a disc brake diff, I assume a T series. photo below.




Thanks, Steve
