Hello all, obviously new here and new with an X5 E53.
I would appreciate any help or advice.

Few months with my 04 E53. Generally happy. Noticed the car is making a very -very very- loud metallic screeching sound when I turn the steering wheel -mostly to the right. The sound is coming from the suspension or rack or something. It is very very loud. It also does it when going over speedbumps.

Anyone has any idea what this could be?

many thanks

Hello and

Things to check are: power steering fluid level, power steering pump, any sign of leaks around the PAS system generally - the hoses were a known issue in 2004. Worth checking front wheel bearings and drive shafts for excess play or noise (rumbling, grinding).

Also check all the auxiliary belt tensioners, perhaps remove the belts and see if the noise goes away

On my old V8, the horrendous noise mine once generated was a seized alternator pulley. Hard turns strained everything to a point the belts were under huge pressure hence the really loud noise.
