Tech Tips:
1) The axle variant may be found on the identification plate located next to or on the differential housing.
An example ID plate is attached for your reference, alternately the axle variant may be located via a VIN number decoder
2) Ensure the thrust tube ball is clean and smooth before fitting a replacement cup set.
Use some 1200 grit wet & dry emery paper with a suitable light grade lubricant to remove high spots and surface rust as needed.
In some instances you may need to start with a coarser grade abrasive such as 800 grit to remove corrosion.
Do not use powered tools or very coarse abrasives (less than 800 grit) as damage to the ball surface may occur.
Use liberal amounts of LMM grease (molybdenum disulphide) to lubricate the joint prior to reassembly.
