How Much Oil Does A Semi Rear End Hold?
Emily Cortez 
The various system components of a semi rear end have a combined oil capacity of 4-5 gallons. A front-wheel-drive vehicle’s drivetrain is comprised of these parts, which are responsible for transferring energy from the transmission or differential to the tires (in a rear-wheel-drive system). If one of your car’s axles has been broken or completely shattered, you should not attempt to drive the vehicle at this point. The technique is not without its risks, to put it mildly.
Poor lubricant application, particularly in high-performance applications where specialist lubricants are used, is a significant cause of differential failure in these applications. The differential oil fails as a result of the emulsification produced by the presence of water within the difference. As a result, the surface areas of the gears and bearings are being eroded over time.
A differential failure can occur when seized U-joints cause the system to shake excessively, resulting in the breakdown of the differential. It is necessary to remove the differential cover in order to clear out any old fluid, re-seal the cover, and add new fluid to the rear differential. The life of a rear differential fluid change is normally between 20,000 and 40,000 miles before it requires a second service appointment. Expect to pay between $150 and 280 dollars to replace the differential fluid, with the rear differential fluid replacement costing on average $80-$150 and the front differential fluid replacement costing on average $70 to $130 dollars. The cost of differential fluid replacement ranges from $150 to $280 in total.
