Finally after a winter of welding,filler,painting,making fuel lones,service I thought it would be good to run the the car on pillar with wheels in air just to see if anything more would occur and sure did.
Speedometer work in idling in drive but as soon as I put foot on gas pedal the needle goes to 0 on speedometer and when rev goes down it catch up again at 20km/h. Wire seems to be ok but my car has geardrive in to box and is a 1982?
I also hear a knocking noise when acc.and deacc…knocking seems to come from rear support of gearbox. Bushing seems ok looking on it
Finally a contact housing hangs down and I striped it back. I also notice that a cover is missing
So here are my questions:
Speedometer:is my problem a typical angle gear problem?
Cover:surely there should a cover over the big hole,right?
Knocking noise when gearbox moves:Bushing broken?
Wire harnes: what is the 4 pole contact for?
Top picture show contact and cover missing. Below is just angle gear
