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
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
