Optimistically speaking - let's assume that the grinding / whirring bearing noise isn't the torque converter or the transmission... everything feels smooth in that area and gear selection is operational without fault.
This leaves the notorious front diff / shaft issue.
Having read some useful info (thanks SaintV8) it appears that LR Customer support hasn't been completely honest with me over my 'VIN' not being effected by the front diff recall - and it definitely hasn't been upgraded.
- at 73k and an easy life - it could just be showing the signs of failure.
The splines may still be holding on - but another effect of the misaligned front shaft is lateral pressure on the diff input shaft and tapered bearing respectively.
Could it be that the initial noise is the knackered diff tapered bearing running dry until the first few minutes of driving distribute oil from the main housing of the diff? Even though the loud 'whirring-bearing' noise does disappear quickly - I do have very light whirring after the car has warmed up.
I'm back to speaking with LR Customer Support with a view to getting the Front Diff recall done. They've made it clear that the recall ended in 2011 - and I purchased the car in... yes you guessed it.... September 2011. The way the conversations are going with LR - I'm being asked to demonstrate that the diff / shaft is actually failing... I'm at the mercy of my local main dealer's inspection of the diff now. I'm hoping that their approach is that it's in their interest to write-off the front diff / shaft assembly in order to get the upgrade approved by head office... and consequently 'paid for the work'.
I'll keep you all informed as to how many more hoops I have to jump through before they (if they) offer assistance.
Thanks again everyone. If you have any additional comments on the noise in the video - please continue with your input for the benefits of others on here.
Mark.
