I just changed all the drivetrain fluids on my 2010 Range Rover Sport HSE 5.0.



For the Front and Rear Differentials I used Mobil 1 75-90 LS. I do not have the rear locking diff which calls for special fluid.

For the Transfer Case I used Royal Purple Syncromax because my Owners Manual called for Shell TF 0753 and the Royal Purple cross referenced.



My front and rear diff both used 8mm Hex for the fill plugs. The drain plugs were 3/8 square.

Transfer case was 8mm Hex for both drain and fill. I did not replace the plug or crush washers just reused. Everything was just snugged down with a 3/8 short ratchet. I used Permatex High Temp thread sealant on the diff plugs.



See the attached YouTube video for what the fluids looked like. They were probably replaced before my ownership at 30k. Fluid came out pretty clean except for the transfer case.







Couple of questions for those of the community.



Does anyone have the torque spec for the large lower bolt that holds the bottom of the front struts to the lower control arms? I believe the shop that installed my lower control arms torqued the bushing on the struts at full droop instead of ride height and I want to loosen and retorque.



I have a small squeak at engine shutdown, typically on other vehicles I've encountered this is usually the Alternator Overrunning Pulley (OAP) has anyone encountered this?



Thanks a bunch.
