O-Ring - Diff Lock Selector Shaft - LT230 Transfer Case

This O-ring seals the differential lock selector shaft where it passes into the LT230 transfer case housing. It sits on the selector (cross) shaft that operates the diff-lock engagement fork, keeping transmission oil from weeping past the shaft where it exits the casing.

A perished or hardened O-ring here lets oil seep from the diff-lock selector housing and can let air into the mechanism, giving sticky or unreliable centre-diff lock engagement. Replacement is recommended whenever the diff-lock selector housing, fork or shaft is disturbed.

Frequently asked questions

What does the FRC5576 O-ring do?
The FRC5576 O-ring seals the differential lock selector shaft where it passes into the LT230 transfer case housing. It sits on the selector (cross) shaft that operates the diff-lock engagement fork and keeps transmission oil from weeping past the shaft where it exits the casing.
Is FTC1441 the same as the FRC5576 O-ring?
Yes, FTC1441 is listed as an alternative to the FRC5576 for the LT230 diff-lock selector shaft. Either part number covers the same sealing location, so if your supplier references FTC1441 you are looking at the equivalent seal.
What happens if this O-ring fails?
A perished or hardened FRC5576 lets oil seep from the diff-lock selector housing and can let air into the mechanism, which shows up as sticky or unreliable centre-diff lock engagement. Replace it whenever the diff-lock selector housing, fork or shaft is disturbed, as a disturbed O-ring rarely reseals.
Which Land Rovers does the FRC5576 O-ring fit?
The FRC5576 fits the LT230 transfer case on Defender 1987-2016, Discovery 1 from VIN FA393361, Discovery 2, and Range Rover Classic up to VIN HA610293. Check your VIN against these breaks, as LT230 detail changed across the model runs.
