My 2004 suzuki xl 7 makes a squealing noise after I put it in drive and goes away after a few seconds. Does not squeal when in park.

SOURCE: 2004 kia sedona replacing alternator

I've managed to replace mine now. There seems to be little advice/experience of replacing an alternator on a Diesel engine in a Sedona. For mine, I removed the brake master cylinder assy, without disconnecting the pipes. This gave slack to move it over to the side, leaving a gap in which to work and space to draw the old alterator out. I also removed the radiator from the top of the engine, leaving a bit more space. Taking away the RH wheel and splash guard gave access to the belt tensioner and crankshaft nut, to be able to turn the engine over.

I also found it necessary to remove clips and clamps from various pipes so I could move the pipes and wires around a bit.

All in all a tricky job, but one which would be only half the job now I've done it once!

SOURCE: squealing NOISE possibly from fan belt

Belts stretch from new. Try to tighten them again. Hopefully the are not glazed or this may stay with you.

SOURCE: Help! Air conditioner causes squeal soon after turned on

The ac is belt driven, If one of the belts are loose it will make a squealing noise. Turning on the air puts more strain on the belts. If this is the case all you would have to do is tighten the belt or belts. This would probably take a service tech just a few minutes. Probably under $100.00 dollars..........

SOURCE: alternator drive belt squealing

yeh, mine did the same thing with a hydralic belt. it was the bearings. mazda capellas use a lot of 6202 bearings which, luckily, are fairly cheap, and are commonly used in pool pumps. so you can find them at pool pump repair stores. although pool pumps use 6202 2RSR bearings. these are just the water proof type, but are excactly the same size and can be used.
to test if it is a bearing problem, remove the belt and try to twist the individual wheels by hand, you should be able to turn the 2 smaller ones.
from memory the alternator belt is in a fairly in accessable postition so the belt is going to be hard to put back on.try other things first, like wiping the inner side of the belt with a dry cloth to remove moisture.
worst case senario is your alternator has, or is starting to, seize up and you need to replace it.

SOURCE: while driving a squealing noise comes from the

you need to check the front brake pads to see if the warning tab is touching the rotor ,this will squeal if the pads get worn out before it goes metal to metal, and if that is ok the only thing i would think of is the wheel bearing,
