How hot should rear differential get?
from a lube oil standpoint, 100-180’F is about the range to be expected. some diff covers have cooling fins on them. thus the requirement for synth lube for towing, etc.
What can cause excessive backlash in a differential?
The pinion gear is supported by two bearings, whose pre-loads are established by a crushable spacer between them. When a differential is set up this spacer is crushed by tightening the pinion nut; if the spacer is crushed too much, you get excessive backlash.
How do I know if my limited slip differential is working?
The easiest way to tell if you have an open differential is to jack up the car and spin one of the rear tires. If the other wheel spins in the opposite direction, you have an open differential. If it spins in the same direction, you have a limited slip differential, or LSD.
Is a differential supposed to be hot?
It’s hot enough to where you can still put your hand on it, but you sure wouldn’t want to leave it there for long. Seems to be warmer near the pinion.
What temp does gear oil break down?
No matter which oil used, the higher the heat in the diff, the faster oxidation occurs and the oil breaks downs. At 140 degrees if no trash or moisture is introduced oil will basically last a million miles. However for roughly every 20 degrees above 140 it cuts life expectancy in half.
Why is my rear end popping?
Knocking Noise A knocking or clicking sound may be due to the splines on the axle shafts being worn out, in which case the defective shaft has to be replaced. Another reason for this may be chipped teeth on one or more of the gears in the differential. Again, they’ll need to be replaced.
