I have a squealing noise on my 1999 Ram 1500 pick up when the voltage drops and/or there is a load on the battery (i.e when the fan motor is on high or when I am plowing snow...). When the volt meter shows the battery to be fully charges ther is no squeal at all. I changed the alternator thinking it was a charging problem but it dod not help. Any thoughts?
Thanks

Your truck uses a serpintine belt ( a one piece fan belt), the most common problem with this truck with that complaint is the tensioner. The belt tensioner is spring loaded which normally keeps tension on your fan belt, they tend to freeze up though. All you need to do with the truck shut off, not running, is to take a wrench on the tensioner pulley bolt and try to move it, the tensioner should move, and when released, spring back, if its sticking, it will not spring back real fast. Sounds like its bad, and when its damp or cold, its causing the belt ot slip , causing your alternator to not charge. Good luck

no matter if it truly is coming from the rear it sounds like it would nicely be a differential difficulty. you'l opt for to envision that it nonetheless makes the noise going over small bumps even as vacationing in a immediately line as i assume you're turning even as stepping into your force way. if it makes this noise nonetheless in a immediately line then you would have a suspension situation ( yet you would must be turning not uncomplicated sufficient to create body roll in the motorcar for this to really be the placement). if its diff attempt a diff oil replace (sorrry no longer favourite with those trucks so that you would ought to make sure no matter if it truly is a constrained slip diff or no longer as to what oil you re fill it with) and it you nonetheless have a difficulty purely clarify it to a mecanic and they provides you with some ideas

The only squealing I have ever heard on an engine is slipping fan belts..... make sure they are tight, and not old, when belts get old they get hard and glazed and then they slip and squeal.
