Outer Limits 4x4 Board

hey ppl.

my brothers 80series has created a shutter or vibration under load.
starts at about 50kph so i'd say its in the driveline somewhere??

its booked in to go into the mechanic tomoz morning but was just wondering if anyone has had a simular or the same problem? and what did it end up being?

any help is appreciated. cheers.

Part time? I had it when I was under load or engine braking. When coasting it was gone. Drive shaft and rear diff. But, start with unis and slip joint on rear drive shaft.

Constant 4wd. mechanic said could be rear uni's. hopefully thats it.
cheers mate.

When mine was constant was the slip joint on the front tailshaft

Thanks for your help guys. You's were spot on. Uni's seezed up and fuk'd the front drive shaft. slip joint is fukd, cant even get it apart.

new shaft is on its way. thanks for your help.
