Description
This is a rebuilt Range Rover Viscous Coupling supplied on an exchange basis.
A common problem with the Range Rover BW transfer case is a “seized viscous coupling”. This can easily be identified by the effect it has on cornering, the tyres will “chirp” or “scrub”, as the vehicle is effectively permanently in diff lock. As a confirming check, put transfer case in “neutral”, handbrake on, jack up one front wheel and try to turn it, it should turn slowly with resistance, if locked solid the viscous coupling is seized, and will need changing before any damage to the diffs or CV joints occur.
A more comprehensive check of the unit is in the Technical info section below.
The coupling can be replaced with the transfer case in the vehicle but the case will need securely supporting, as the RH mounts are part of the coupling housing.
This is the same part in the Classic and P38 Range Rover, RTC6044
Please note that if the vehicle is approaching its century, i.e. 100k miles it will be well worthwhile considering a replacement transfer box as the chain, output shaft, and pump will almost certainly need attention. Please refer to transfer box section for further details.

This is a great rebuilt unit from a reputable rebuilder. No worries of wasting time by installing a used and suspect viscous coupling unit. Shipping to the USA was quick, albeit a little bit expensive. Unfortunately, the $75 core return fee over the pond is a wash due to the cost of return shipping. Despite the added cost, I have no regrets. Convenience and quality is worth its weight in gold.
