Hi
I own a 2004 exceed 3.2 diesel.
The problem is a bad grinding noise coming from the rear end, i first thought it was the brakes but have had them checked and its not that, the noise only occurs first drive of the day and only when accelerating. Just today I went to my local mechanic and he put my car on the hoist with the wheels free I started the car put it in drive and no noise while idoling but as soon as I just touch the accelerator the noise starts and the mechanic said he could see the rear wheels were a bit jerky but was unsure as to what the problem could be.
Any idea or help would be great.
Cheers

A bit more diagnosis might be useful - is it a constant grinding or does it sound cyclical/rhythmic? If rhythmic, drive slowly and note whether the frequency is every wheel rotation, or more often (would indicate diff pinion).
I'd drain and refill the rear diff,
check the old oil for any signs of contamination or metal fragments (noting it's normal to get a bit of metal 'paste' on the magnetic drain plug).

the noise is constant for around the first couple of hundred meters of driving first drive of the day and than is gone
