Driving around today, I went over a couple of very small bumps on the road and heard a metallic grinding-rubbing type noise for a second or so from the driver’s side underneath. Seemed to be coming from towards the front wheel.

On the way home, I heard the same thing again, but this time it was longer. Lasting maybe five seconds.
The last one really concerned me, felt the shuddering through the cabin and thought I might have to pull over, but then it stopped.

It was the first time I had driven it in 3 days.
Mechanic is going to have a look at it tomorrow, anyone on here got any idea what it might be?

Cheers,
Scotty

could just be a small piece of stone stuck between brake pad and disc. I've had same noise before and this was the problem.

Yep I agree with Andrew. However the first part of the Question I went over a small bump! does tend to throw me a bit

But a good place to start.

On the shock mounts there is a washer which has a lip on it and sits in the mounting hole. Some times when the bushes wear the shock can rub on the washer wearing it away. The washer is only soft and once its worn away the shock will then rub on the chassis. Usually only happens on the front top mounts.
If you have to replace the rubbers, only use toyota rubber ones and not the neoprene style ones. I've had nothing but dramas with the after market ones.

Just a thought.

Had the same thing happen to my 80 LC. Turned out to be the bottom bolt from the brake callipers had come out. calipers scraping against the inside of the wheel rim. May be worth checking out

Thanks guys,
Had the tyre off this arvo but can't see anything untoward.
Took it for a spin earlier and it happened again, this time for a minute or so until I stopped.
The rubbing-grinding noise slowed as I did, which does indeed point to the front tyre in some way. It kind of felt like the park brake was on when it happened, and the vibration felt a bit like the tyre was coming loose.
At least now I have some ideas to throw at the mechanic tomorrow.
Might test it again now.
Cheers,
Scotty

Try reversing down the drive faster than normal, and throw on the brakes hard a couple of times. You can get a stone caught in the caliper somewhere, and doing that can chuck it out.

And, being Jonah, did you test the wheel for excess bearing play while it was jacked up? Could be a stuffed bearing in the early stages.

Lets know what the mechanic found, and hope its cheap.

Yep. I'll put my money on a stuffed bearing.

Max,
Thanks for the advice.
Did what you said and it stopped making the noise. Took it to the mechanic today and he reckons it was almost certainly a rock in the brakes, as many suggested.
Phew!
Thanks to everyone.
Cheers,
Scotty
