1996 I4 differential refill hole

[mk2mr2]

Hi. I am looking but can’t find the refill hole on the differential. Any help would be highly appreciated. I am hoping I can still save the differential. It just started making gridding noise when in reverse or drive when barely moving. Thanks.

The diff fill hole is on the rear face of the diff. fire wall side, there are some heat dissipating ribs that may block your view.

Thanks. I found it but it's making the same noise. I need a new transmission.

Thanks a lot toyotanation!

does sound change with speed change?

Sound just sounds like a bunch of rocks being poured down to the ground. I can't even get it rolling 1" before it sounds like hell. forward or reverse.
