Wheel speed sensors misadjusted, damaged , or metal shavings and other debree, since they are magnetic can give false readings from one of the wheel circuits. Over sized tires can give of false speed readings as well. there are many other causes including bad relay, control module, e.t.c. It is best to have the proper scan tool to diagnose an ABS problem

SOURCE: I need to replace a serpentine belt on a 2001 GMC

it is decieving. if the tensioner has an extension of about two inches from the base, it takes a 15 mm to lift it, be easy, make sure the wrench is not going to touch anything as you release it after taking the belt off

SOURCE: my 2004 gmc sierra has a slight squealing noise

If noise is come from front end, and your truck is not moving at a stand still, it's going to be your ball joint's, bad news, if there OE there will be no grease fitting. New ones will come with grease fitting for future lube jobs on ball joint's.

How do you stop a belt from squealing when you crank the engine? It has a new belt less than 50k and self-adjusting tensioner. I was told not to spray anything on it...


50k isn't new but also isn't that high a milage , how old is the belt ,as age as well as mileage are the factors when replacing belts , chalk dust or french chalk , which are the same thing , thrown onto the belt just as starting should stop the squeal , the squeal is caused by the inner side of belt that runs around the pulleys becomes shiney and cant grip as well as it used to

We tried that, changed belts, pulleys, tensioner and alternator, nothing works. I still have a bad squeal. Do you have any other suggestions?


Hi and welcome to FixYa!

If that's the case try using a fan belt dressing. It can help eliminate the squeals.

Hope this helps and thank you for using FixYa! Have a good one!

Fan belt squeaks, is idler pulley adjustable on 1995 gmc v6


Good Morning

Mine is not adjustable, and I doubt yours is.

There is stuff called "BELT DRESSING" you just spray it on the belts. If that makes the sound
go away then it is time to replace the belts, but you can enjoy the quiet for the time it lasts.

Good Luck

I have a 2006 GMC sierra and the a belt squeaks


If both belts are the same age it wouldn't hurt to replace both of them, spray them with a belt dressing before installing new belts. You can get this dressing at Autozone and possibly the belts too. Good luck.

There is a really load noise coming from the area of the air filter. I think there may be a bearing in the alternator gone bad. Does anyone know if this possible.


Most likely no, check to make sure that all of your pulleys are turning correctly with the belt. If the pulleys are all turning then the thing that is probably causing the noise is your belt. Go buy some "belt dressing" from an auto parts store and spray all over your serpentine belt. Sometimes your belt gets water on it and will squeal afterwards, the belt dressing helps correct this. Hope this works, let me know what happens and I will see if I can help more.

Loud Sqeaul/screech from engine upon start up


could be your alternator. at start up. alternator usually has a big load because you just use your starter. it would recharge the battery and after a while the battery would be fully charge, the squealing noise will be gone.

check also all the belts if they are individual belts. use some belt dressings to eliminate the noise. sometimes the belt are just worn out and it would also make these noises.

tnx 4 using fixya,
