Is it normal for a rear differential to get hot?
as for diffs: they do get hot, it’s normal.
Do differentials get hot?
I put Swampgoat up on ramps right after I got home to check everything out after a track-day, make sure nothing loose or leaking and noticed the diff was hot… like real hot, 1 or 2 seconds touch max. I asked Kurt down at Difftechnics, and he said that, yeah, they get good and hot, no worries!!
How hot do rear differentials get?
Re: Rear Differential Temperature That temperature will vary depending on the exact fluid you decide to use. But a couple general numbers are 250 degrees for a constant max. Most fluids can handle that no problem and you won’t damage anything. 300 degrees is a max intermittent temp.
Why does my rear end get so hot?
Ambient temp had no noticeable effect on sampling temps. The location of the exhaust pipe relative to some of the measured components explains the high reading in those areas. The L wheel bearing is raising all the ruckus. Would you agree that it’s a suspect?
Why are my bearings running hot on my new trailer?
Failure to back off the adjusting nut could cause the bearings to run hot and be damaged. Once you have backed off the spindle nut you will want to bend the cotter pin or tang on the washer to prevent the nut from backing off.
How hot should my rear-end get ( differential )?
Your WRX has a limited slip rear end, which can get get pretty hot during spirited driving with lots of turns (the STI version even has a rear diff temp sensor and warning light), but I don’t think it should be getting scaldingly hot during normal driving around town and during normal mostly straight highway driving.
Why does my rear differential make a whirling noise?
Rumbling and whirring noises at speed over 20 mph, moreover, can be the result of worn carrier bearings. For vehicles with C-clip axles, the rear differential noise may change at different turns.
How hot should my rear-end get at high speeds?
So it’s reasonable to expect a rear diff to get pretty warm after cruising at high speeds. It might take 15-20 horsepower from the engine to keep your car moving down the road at 25 MPH, which might mean ~1-2 horsepower (750-1500 watts) being lost to the diff as heat.

What causes a brake hub to heat up?
If the drum brake pad pressure is adjusted too high or if there is a damaged component in the brake assembly those things could also cause the hub to heat up to an excessive temperature. Since you did recently install a new brake shoe I would check that installation.
Failure to back off the adjusting nut could cause the bearings to run hot and be damaged. Once you have backed off the spindle nut you will want to bend the cotter pin or tang on the washer to prevent the nut from backing off.
