No one came up with it! I'll tell you now!
on the drive shaft, the shaft is plugged into the gearbox side in the warehouse and slip out from behind by a safety ring! yes and this safety ring (the stupid sow the) has gone off....and so the wave has slipped out so gradually and had not transferred the power of the transmission to the wheels! and so on.....
I made the encapsulation at the back of the shaft with a hammer (2 times hammered on the fins) the safety ring just bent back again pure tensed new grease lubricated all assembled again and after 6 std out and installation action the audio now goes again!!!
oh yes the drive shafts of the 89er do not fit in 91er!!! have two for sale for the 89er (front left and right)
until the next one!!!!
