noise is driving me mad

[dave benson]

This odd rattle has appeared on my rallycar,it's a Honda Civic EK4, when going over manholes / potholes.

I have been trying to cure it for a couple of monthe on and off, so far its had new hubs bottom balljoints, new bottom arm bushes, new s/h steering rack and new trackrods, both front avo stuts checked -both fine, i then changed the driveshafts, both inc. the intermediate one.

result, the noise is still there

now one thing i discovered before is that left foot braking/ being on the power at the same time, whilst going over holes / grids stops the noise !

could it be the diff ? its a kaaz plate one that has done 350 miles from brand new

the gears and crownwheel / pinion are a similar age

any ideas please ???

probably your diff?

ha ha sussed it after weeks of trying

brake pads !! ds3000's rattling about in the spoon calipers !!!!

the clunk of the diff was resonating through the calipers/pads and making it sound like a noisy diff

cheers
