I recently experienced a similar sound. It turned out to be the driver's side front wheel bearing. After jacking up the front end, I was able to rock the wheel back and forth by grabbing the top and bottom of the wheel. I have a 2005 Ram 1500.
The pump will need replaced if it is grinding.
Its usually a U joint. Click under acceleration . While turning,a CV joint. Grinding or moaning is usually a bearing.
Why is your 1993 Altima Nissan making a clicking noise but does not start?
Sometimes a clicking or grinding Sometimes speedometer needle will fluctuate
New CV joints will fix the grinding noise
I have the same problem if it was making a grinding noise contact ego-fly if its not making a grinding noise the rotors might be hitting each other
The grinding noise in the front of a 1990 Dodge Caravan could be a cv joint. If it is, it probably only grinds when you take a sharp turn. There is one located on each side.
Cicadas
drive belts tensioner/under chassis
A bad resistor can cause your BCM to make a clicking sound. The clicking noise can be caused by the relays and replacing the BCM will fix the problem.
Bearing going bad?
What you are hearing is the clutch on the air conditioning pump engaging... the alternator doesn't make any noise unless the bearings are going bad and then a grinding noise will be heard.
