How hot should my rear-end get? (differential)
somepumpkin1
My car’s rear differential, that is.
Short version:
How hot should the rear differential get after a 30-minute highway ride (~65mph)?
Should it be so hot that I can’t touch it, or should I be able to rest my hand on it and enjoy the warmth it offers?
2003 Subaru WRX, stock (no modifications)
180,000 miles
80F ambient temp
Longer story:
There’s a significant whining/whirring sound coming from the rear of the car that was barely-noticeable about a week ago.
I had my buddy ride with me and crawl around the inside to confirm that it’s coming from the rear differential area.
Semi truck differential overheating
It gets progressively faster as the car moves faster, and I can even hear it as I come to a stop (down to ~10 mph) when it sounds like a soft grind or rub. The sound is unaffected by gear selection or brake application, and the only effect that accel/decel has is to speed-up/slow-down the frequency of the sound.
It gets more-pronounced as it gets warmer, too.
I (stopped first) got under and touched both rear brake backing plates and caliper
