I've also got a HDJ81 Ive imported from Japan - she's got 104Km on the clock. I live in Zambia. The BEB thread(s) have got me concerned, and I've tried to source someone that will replace them. Zambia won't touch them, and even Toyota South Africa won't touch them - they said they'd farm it out to an engineer. The mechanic said he wouldn't open it without the engine losing oil or clicking....
Confuterated in Zambia...
Try the guys on the SA landcruiser forum. They are well informed on this matter and know who can do it

It shouldnt be ignored as it can be catastophic and getting someone to fix it will be a damn sight harder in Zambia
