Right front wheel noise

Hi: When I first noticed the noise, the first thing they did at the garage was grease the steering knuckle, as they found it was dry. But the problem persisted. Days later, they sprayed all the parts in contact with the wheel (including the suspension, shock absorber, etc.) with a lubricant, and the noise disappeared for about eight days, but then it returned.

Thank you very much for your comment.

The problem is that there might be several parts with rubber seals, and according to some catalogs I've seen, the price of the parts themselves wouldn't be very high. The expensive part would be the labor to remove the old ones and install the new ones. Besides, it doesn't make much sense to replace parts that aren't causing any problems.
Thanks for your comment.
