Frequently asked questions

What is the RTC4489 differential gear set?

It's a replacement gear set for the differential, containing the crown wheel and pinion gears that transfer drive from the propshaft to the axle half-shafts. Fits Series and early Defender models with a suffix A or B axle up to 1978.

How many gear sets do I need for a differential rebuild?

One RTC4489 set per differential housing being rebuilt. Check your axle's suffix marking (A or B) against your build date before ordering, since early Series differentials used different suffix codes.

What does the axle suffix A or B mean for fitment?

It refers to the axle casing revision fitted up to 1978. Suffix A and suffix B axles used slightly different internal specifications, so check the suffix stamped on your axle casing to confirm you're ordering the correct gear set.

Is fitting a differential gear set a DIY job?

This is typically a specialist job. Setting correct crown wheel and pinion backlash and contact pattern needs specific tools and experience, so most owners have this fitted by a workshop rather than doing it themselves.
