I'm driving a 2000 Chevy S-10 4x4 with the 4.3 that has 66,000 miles on it. a few weeks ago I started to hear a loud squeal that appears to be coming from the drivers side front tire. the squeal occurs erratically - never below 45mph, usually when at cruising speed of 65mph, it comes and goes with no set pattern, I can drive long distances and not hear a thing (75 miles) and then hear it with in 5 miles of starting, does not change with brake application, does not change with shifting into neutral or engaging the 4wd system or with revving the engine. there is very little difference with speed - sounds the same at 45 mph as 75mph. the sound is very high pitched and sounds like a belt slipping - but doesn't change/start/stop when the AC pump engages. what I've done to the truck prior to the squeal starting. About 6 wks before the squeal I changed the Automatic transmission filter and fluid, I changed the front and rear differential fluid, I changed the transfer case fluid, I put on a new belt. last year I changed the universals on the driveshaft and replaced them with greasable ones. What I've done since the squeal started, pulled both front tires, inspected the CV joints, front brakes, regreased all fittings, inspected universals - greased them too, inspected all front suspension components. - everything looked good - also checked the front hubs for excessive heat after a 75 mile run - no excessive heat, shook tires to check for movement out of the front wheel bearings, and wrapped the drivers side tie rod adjuster with duck tape (heard some of them whistle). Running out of Ideas, I'm gonna check the rear brakes - though the sound is clearly from the drivers front, tires are a little worn - but not worn to the wear tabs on the tire, will change them this fall. Really pulling a blank here... any input at all from you guys will be appreciated...

we have seen inner axle seals squealing on t trucks /
yes it's true the axle is rubbing the seal
may want to look in that area
good luck

Do you mean the seal on the front diff? is that rebuildable, or do I need to take it to a pro to have done?
I have had CV boots make a squeaking/squealing noise before...
components. -
I was wondering about that, my sisters '99 Cavalier was squeaking, pads were worn but not to the indicator, so I replaced them but the squeaking persisted, especially after accelerating from a dead stop/low speed (which is why I thought they were the pads). How did you deal with squeaking CV boots?

Hey I appreciate the reply, great info... I'll try the wheel cover first, it's only happening on one side so if it works I'll do it on all four. If not I'll try the CV joint method. You recommend any sort of silicone spray on the CV boots or just leave them be? thanks again
YES, there is! Its a rubber type squeak. It happens when the folds of the boot rub against each other... I have come across it very seldomly. It IS possible though, Shiden! Just because you have never come across something doesn't mean it isn't so! I am NOT trying to start a yelling match in the NG. A difference of opinion is no reason to have an argument and it is the reason so many of them have started on here.
