I have the infamous seat of my pants vibration for the first few miles when cold... Ususally spells centre support bearing, but could also be gearbox mounting or U/J also. Is there a way i can acurately diagnose the cause....?

I had this happen to me a while back. Think theres a much greater chance it being the prop bearing. Although its not actually the bearing that goes its the rubber around it that sags causing it to hunt for the centre hence the vibration. Go with the prop bearing first.

remove downpipe exhaust section's

remove heatshield which covers propshaft lift complete propshaft and check for excessive play!

 

also check as said above^^the rubber inside the coupling tends to split with heat and wear if so replace centre support bearing,follow guide on how to,its not to bad a job to DIY

 

if it checks out ok,check gearbox mount,a lot of these are now worn and are shown by supoorting gearbox and dropping the 6 14mm bolts on the mount then check for play,but mostly its prop related

yes you do buddy,mark where the prop splits with tipex on both joins that way you know the reposition and it makes sure the prop is within balance

 

DIY mate if you have any probs give me a shout :duffer:
