Hey guys and girls!

We're about to dabble our toes into the world of defenders following being stung for a hefty chunk of money on another vehicle and getting fed up of the non-simplicity of fixing it..

Anyway, we've found a 2002 90 we like, with 95k miles on. Upon viewing the vehicle today, I've noticed a leak from the transfer box, oil dripping is clear. The seller reports a full service (gearbox and engine) was carried out recently and all oils replaced. Could this potentially be a leak/corroded seal or even just mess left from the service?

Cheers

If that is your only issue with a 20 year plus truck you are very lucky.
Only a thorough clean up will disclose the exact cause of the leak. Also I think the oil has a red hue which says main box oil. Anyway it will be basic fix of gasket or seal, how much cost depends on which one.
Most important is the condition of bulkhead and chassis so double check them and if you do not know Landys have someone who does do the checking. Age matters little, condition is most important.
Some good Defender purchase check videos on the You tube.

There are a number of 'common' leak points on an LT230 transfer box.
They are all relatively easy to fix with the intermediate shaft being the most time consuming and requiring the box to be off the car.



It really needs a good pressure wash/clean and then an examination to find the source.
