Front end clunking noise

Take the brakes apart & clean up all rust,check everything out
& lube things when putting back together
Have to do that at least once a year

Don't need machining every year or new pads, but have to knock
down the edge on the rotors & get rid of rust & lube (anti-seize on
everything but inside the caliper slide bolts, there you use the synthetic caliper lube

The clunk could be worn drive axle joints or drive shaft joints
or shocks
When your on the brakes or hit bumps your loading things differently & the clunk goes away

The abs lighton my 2000 mercury mystique comes on and the brakes make loud noise

The noise you hear from the brakes? is it a scraping grinding noise? if so your metal to metal on one or more of your wheels and that can cause the ABS to mal-funtion. If the brakes are good then it sounds like the ABS module is failing. I wouldn't remove the fuse because other systems may be relying on that fuse to work. Find the ABS module and dis-connect it. To find out more information on your ABS system go to your local library.

Fiesta (Unwanted Noises)

Go to the site and look up your Year of Ford Fiesta. Any Recalls and Consumer complaints would be listed and useful to you.

I suggest the grinding noise may be an Electric motor like your front Radiator fan motor. It would fit with the symptoms of a constant grinding noise unaffected by engine RPM or Vehicle speed. If you have a later model Fiesta, some are starting to be equipped with Electric steering motors which also would remain in constant motion independent of vehicle speed.

The clunking can be a second problem. Some early Fiesta's seemed to eat the front struts. Some of the Ford models also used a Bearing ring sandwiched at the top of the strut. This assembly was meant to replace the upper ball joint. Contact a good Autoparts store about exactly what parts your strut assemblies have. Some of the autoparts stores have tool loaner programs to help you install the new parts.

Hello and welcome to FixYa!
As a first course of action, I strongly suggest that you have the bushings checked. They can be worn out that's why during take off you can hear a clunking sound. Do check the brake pads too for if they are worn out you'll notice a metal to metal noise.
Hope this helps and thank you for using FixYa! Have a good one!
