Thread: ACE is thumping

I would be removing the belt and checking the pump's bearings quick smart, although it could be loose mountings.

I dont think its either the thump have to big of a gap between them to be a bearing its like thump 1234 thump 1234 thump

mmmmmm

What specifically makes it thump or does it thump all of the time?

ie turning left to right and/or right to left? driving over little bumps, driving over big bumps etc?

If its like a rattle, the rose joints you have can do this as they develop slop.

No it’s not the rose joints I know them LOL

its noticeable on Idle on a stand still when I lift the bonnet I can visually see the hoses that go to the ACE reservoir thump when I put my hand on the reservoir I can feel the thump its funny I cant here it whooosh noise that the ace does any more light flashes on and off here and there

Starting to sound like a problem with the pressure limiting valve or a blocked filter in the valve block beneath the driver's floor. Maybe its simple like a bad electrical connection but a hookup to an appropriate diagnostic device is probably needed for more info.

Edit: Worth checking the electrical connections on that valve block.
