Rear diffrerential weepage

[F1Fifty]

I went in for an oil change at the dealer recently. The tech noted a rear differential weepage and their next available appointment for repair is in May.

Does anybody else have a rear differential weepage?

Seen a few reports on leaking pinion seals in the rear diffs. and I wonder if it has anything to do with the throttle pedal vibration many are experiencing as an out of balance driveshaft can cause this.

Good luck!

Nothing worse than rear-end weepage.

Man that flange looks so much better than my brand new one in terms of rust. I'm a tad worried about catching leaks after having done the fluidfilm.

..I'm a tad worried about catching leaks after having done the fluidfilm.

There are UV dyes that can be used and multicolor kits are used in industrial settings to find out what exactly is leaking when multiple possible sources are present.

Other than AC systems, it’s usually not necessary for automotive applications.

Fluid Film is a lanolin based oil and the gear oil in the differential is likely going to be thicker and darker. Sometimes, different lighting is needed to differentiate between existing oil leaks or applications and fresh stuff. Also, in a dusty environment; gear lube leaks are really good at getting grimy.

Let me know how it goes, I hope my dealer doesn't drag their feet! I wonder what the cause is as well
