So I bought a new Defender to replace my 1996 300tdi that was nicked and arson'd on Sept 1st.
Everything is great on it apart from two issues. When travelling over 50mph there is a rumble, not sure it's safe to say it's a vibration as I can't feel it in the pedals or really in the steering wheel but I can hear it very noticeably.
The other issue is that when braking hard I can feel the smallest of pulsation through the pedal. I guess one of my brake rotors is warped.
For the rumbling this is what I was thinking to do to help diagnose it.
1) Put the transfer box in neutral and throttle hard as if I am accelerating.
If I can hear the noise again it means it's engine, flywheel or gearbox and I should begin crying now. If not I should move on.
2) Drop the transfer box into High and Diff Locked, remove the front propshaft and accelerate hard.
If the noise is gone, prop shaft to be replaced. If present, reinstall prop shaft and repeat with rear propshaft.
If still present could be transfer box or additional components further down.
3) Have wheels checked for balancing,
Then after that I guess get the warped rotor looked at and see if that makes any difference.
Any thoughts?
