diff groan and clunking
I just finished a lapping day at the local gokart course and noticed after getting some gas that there is a curious noise coming from the rearend that wasn't there this morning. The noise sounds like a groan and sometimes a clunking. This is while going straight no turns. Best heard off throttle but can hear it from 2-4.5k rpm when accelerating. I had changed the oil to Mobil 1 75w-90 about 50 miles before the event. Any ideas?

You could have a broke axle maybe??
Easy thing to do is…Drain the diff oil and check the drain magnet for junk also check the oil for heavy metallic sheen. If you only have a bit of fuzz on the magnet and a light metallic sheen then the diff maybe ok. Good luck

Could it be anything else you think? I'm assuming it's the diff...
If you broke an axle, it should be very very very obvious when driving.
Good luck!

How obvious is obvious? I was just reading about that tsb. I did have a click accelerating from a stop a couple of weeks back. At first it was on one side but now they alternate on whether each side does it or not. Hopefully it's the axle nuts. Though ive read that if left not fixed then the bearings or axle could fail.
After driving it today I noticed that it is speed dependent. Ill jiggle the axle tonight to see if there is any play besides side to side (left to right) instead forward and backward.
Little info on the car if it helps: 74k, lowered .75 inches with Koni yellows/gc combo about 1k miles ago. Everything else is stock.
