Have an issue with the beloved E85 3.0si - 40,000 miles.
It started with propshaft spitting out two bolts caused by centre bearing failure. Sourced replacement prop complete with good centre bearing and very good rubber doughnut, from breaker with car said to have done 41,000 miles. Fitted, new wheels and tyres all four corners (less than 250 miles all round) and front balanced again last week (not much weight added), all seemed well.......but.......
Took car from Staffordshire to Snowdon for a little walk up the mountain - its first "fast" outing since prop fitted, new wheels, tyres and balancing. From low speed to 75 all is well, 80 car starts to vibrate, (on the autobahn to Snowdon) the car shakes pretty violently between 80 and 90......kph
for any police interest!!
Z gone to BM specialist along with my old prop, knackered bearing and good doughnut. Full inspection carried out; suspension, wheels, tyres, wheel bearings, gearbox (manual), engine mounts etc etc etc - all in good health.
Prop being taken off, original one being balanced, new bearing to be fitted with original doughnut, carefully refitting my original gear. Waiting to hear outcome end of week, trusted, well respected BM specialist.
Any thoughts from expert minds.....?
Thx
