Some kind of lubicant coming out of center hub on back wheel. This is a 2002 Chevy Silverado truck with 77,000 miles.

Wheel bearing on the right front

Hi...your problem might be coming from your front wheel bearing hubs. They are know to cause this problem as they wear out and eventually have to be replaced.

If I helped...please rate me...thanks!

once all the lugnuts are removed give the wheel a large kick,as it may be stuck onto the backing plate.(wheel hub)

I owq a 2002 Silverado 1500 pickup the tow light willnot come on

jack up pull wheel, pull brake caliper and bracket, take nut off axle in center of bearing on back side where axle goes in should be 4 bolts make sure to dis connect abs sensor cause its comin with the bearing that should be bout it some times they come out hard but the will come out

You will need to have the parking brake adjusted to the minimum clearance possible and double check the shoes & drum while off.

It sounds as though the shoes are loose, they move forward, grab & unil you center the brakes by applying them and then they release until put into a bind again.

These usually don't get adjusted or even looked at since they are hidden inside the brake rotor hub on the rear wheels.

good luck.

Will be on the wheel hubs.There is a service bulitin on this year.
Just had mine in a few months ago and the cleaned them and replaced the tail gate cables for free.Hope this helped.

Raise the truck. Remove the wheel, brake caliper, caliper mounting and the dust cover in the center of the hub. Remove the ABS wiring, remove the large nut from the center of the hub. On the back side of the hub are 3 bolts, remove those and the hub should come off. Good Luck

REMOVE BRAKES, ON BACK SIDE OF SPINDLE REMOVE FOUR RETAINING BOLTS AND HUB ASSEMBLY SHOULD COME OFF.. MAY HAVE TO TAP WITH A HAMMER TO BREAK FREE FROM THE SPINDLE... BE SURE TO THOUOUGHLY CLEAN THE SPINDLE BEFORE INSTALLING NEW BEARING ASSEMBLY.

Just to make sure they are a sealed hub and bearings...remove the brakes and rotor and on the back side of the hub there is four bolts remove them, remove outer nut on CV shaft, then pull hub from housing. clean hub seating area then reinstall.
Was thinking that's what i did on mine, just becareful when you place the ABS sensor back. line it up so you don't have to take the wheel back off. Good luck and hope this helps
