Grinding noise while accelerating

Thething · Jun 14, 2013

I'm hearing a grinding noise while I have my foot down, when my disco 99 is over 2,000 rpm's. it only happens while I have my foot on the gas, I'm thinking maybe it's the UJ in one of the prop shafts.
What do you guys think? Could I be right or could it be something else?

When you say grinding noise, do you feel a vibration too, like a "thrumm thrumm thrumm" (gets ready to have **** mercilessly ripped), which to me would suggest something rotating whilst being out of balance? If it's just a noise, you sure it isn't the roar of the turbo diesel "getting on it" ? (Is your a diesel? Someone implied it is, but you never said)

It's a Diesel mate, I've been listening to the engine whist driving and the sound is constant while accelerating but only really noticible at high rpm's.
I sounds like grinding metal. Although my turbo is getting a lovely roar now I've removed the pooped EGR.

Thanks for the interest buddy

Notice the wink?

I've next to no idea, but is the noise coming from under the body or in the engine bay. Some noises are hard to locate initially

It's really hard to locate, it seems to be worse on occasion or I could just be imagining that Diff :/

I checked the front, seemed okay and gave it a good squirt of grease.
I'll check the back one shortly.

Could it be the transmission??

When was it last serviced?

Thoughts of a novice;
If its the turbo or engine related I'd expect it to occur whilst stationary. If its prop related it should only do it "under load" etc but not whilst clutch in/coasting. If it occurs coasting then its more wheels, hubs, etc.

Only does it when accelerators depressed Dave, and it's very noticeable at high RPM's
