I got an audi a4 1998 TDI,i have a rattle/clunk comeing from the drivers side front when i go over a bump. i have changed all suspension arms,cv joint,bearings,discs,pads,shocks,anti rollbar but its still there any ideas.

A "click" or "thump" noise can be caused by several factors, including: suspension: Loose or worn suspension components, such as control arm bushings, control arm connections, and struts, can cause rattling noises when climbing over bumps. Drivetrain: Worn or damaged drive shafts, constant velocity joints, or differential components can also cause rattling noise. break: Worn or loose brake parts such as calipers and rotors can cause a rattling noise when applying and releasing the brakes. engine: If the engine rattles, there may be a problem with the engine mounts or the timing belt. These are just some of the possible causes of knocking noise and an accurate diagnosis can only be made by a specialist after an inspection.

Ball joint or cv axle

indicates that the suspension arm bushes are broken away from the metal bushing at the ends
have a professional suspension shop check for torn insulators in the suspension arm

Good guess, but also tie rod ends should me checked for free play.

A clunking sound in the front is very often the CV joints. This should be more obvious in a slow tight turn. If it is not the CV and is more noticeable on rough roads it could be any one if the suspension joints.

have a shop check the rubber control arm bushings in the front end,they are the usual source of this clunk

you got worn c v joints check for cut or damage boot.

it sounds like the radis arm bushing are wore out they are the arms that go between the frt. axle to the frame they have round bushings that are bolted the the frame rails just behind the frt tires.

Check your CV joint or brake caliper.
