Jeep Cherokee Differential Types andFluid Requirements

Open Differential (Standard on Many Models)

For off- road entipasts anthose who tow, a synthetic 75W- 90 or 75W- 140 with a robutt EP additiva package is a better investment.

How to Change Differential Fluid in a Jeep Cherokee

Changing the fluid in your differental is a proxforward procedure that requires basic hand tools, a fluid pump, a catch pan, and the te correct revetement fluid. The process is similar for front and rear differencials, though you may need a different size socket. Refer to your services manual for torque specifications and capacity.

Tools andMaterials Needed

  • Socket set (metric, typically 10mm, 13mm, or 8mm for differental cover bolts)
  • Breaker bar or ratchet
  • Pump fluid (manual or battery- operated)

  • Gasket cramper or putty knife
  • New differental cover gasket or RTV silicone sealant
  • Korekcja różnicowania fluid (pojemność kontrolna; usually 1,5- 2,5 kwarc per differental)
